Delurk mode. I have a bunch of drill bits that are in need of sharpening, do
the most of you wooddorkers send them out for sharpening like for the TS blades? or do you sharpen your own. I'm not talented enough to sharpen them myself and I won't buy that sharpening machine...looks like it doesn't do a great job, anyhoo...just want some input...I have a professional sharpening service local. I have to call them up to see if they do bits or not, they do ts blades,router bits...very good company and rep. Thanks for the input Tina |

A friend of mine has a Drill Doctor. I have used it a few times. It is not
too difficult to learn to use it, and it works remarkably well. Joe in Denver My Woodworking Website: www.the-wildings.com/shop/ "Tina" wrote in message news:0LVZd.30438$Sn6.1434@lakeread03...

I have one and wouldn't do without it. It's so easy even a 4 year old can
sharpen bits. And the bits come out as good as new. A little shorter though. "Joe Wilding" wrote in message news:1110981749.1289321478136eef61fe0f22efaf3e2f@t eranews...

Highly recommended
The Complete Guide to Sharpening, Leonard Lee. Sharpening skills and woodworking skills go together. It may be better to replace the worn bits than have them professionally sharpened, certainly cheaper to do them yourself. On Wed, 16 Mar 2005 07:38:19 -0500, "Tina" wrote: Delurk mode.

I have a bunch of drill bits that are in need of sharpening I'm not talented enough to sharpen them myself and I won't buy that sharpening machine. Sniped First, if they are brad-point, the Drill Doctor won't work. Second, given your statements, the only other options are to pay someone or buy new ones. (You can send your old ones to me) Really, sharpening a standard drill bit only takes a few minutes and a little practice. Now that your are going to buy new ones anyway, practice with your old ones. I'm sure that if you take a few old ones down to the local machine shop, an old fart will show you how to sharpen them up and get you started. Dave BTW - The Drill Doctor does work fine. I gave one to my dad and he likes it. I however, still prefer the old (faster) way myself.

Mike If you use a lot of twist drill I agree. I've not spent $50 on twist drills in my life so far and probably won't in the rest of it. Now if it did Forstner bits and brad point, I'd be interested. |

I think being able to sharpen bits by hand with a grinder is a really
useful skill. A drill gage doesn't cost much and makes it much easier to get the angles equal, practice with one of your larger damaged bits and compare to a good one till you can get it close. Once you understand how the drill works and practice it really isn't that hard. It's not as easy for tiny drill bits so start with a bigger one. mac davis wrote: ... using the side of a grinder wheel and practicing with a few old bits, even I learned to put an edge on 'em.. I've heard that it's bad to use the side of a regular grinding wheel as they can break and fly apart with a lot of force. That said, I've done it too, and haven't blown one up. But be careful, and its probably better to use the face of the wheel. Hope this helps, Eric |

(Newbie apologising in advance for any breach of good manners in this
post) I find it easier to sharpen brad points than normal twist bits. If you take a good brad point to your switched OFF grinder and settle the bit onto the right-hand edge of the wheel, so that the bit points at your right hip (say, 10 degrees right and 15 degrees down) and memorise that hand-body-grinder relationship, and then take a blunt brad point and, with the grinder switched ON, touch the bit gently on the wheel each side of the point in turn ( no twisting, turning or rocking: move the bit in line with its long axis) you should find that you have a good, sharp bit! And if the bit was blunt, you wont make it any less useful. |

First time in a long time I've disagreed with Mike-
skip the drill doc. Learn to do it free hand. Start with a bigger bit, get a gage, play with it some. It is not hard to learn. the real little bits, I just toss those (or they break).

I do my regular twist bits by hand on my old grinder. Just takes a
little practice. I can't see well enough to do anything below a 3/16" properly though. Just try to get the angles even & keep the point centered. I use a file on spade bits. I send out Forstner's to a pro, though. I buy new brad points, but that's rare. - Jim |

Exactly what I said, except for using a belt sander. Using a belt sander to sharpen drill bits seems odd. A belt can not be as accurate as a stone wheeled grinder. I've worked in and around many machine shops and never met a good machinist that sharpens bits on a belt.

I'll second (or 8th?) that. You can get a full twist drill set for 40-55. The
titanium looks nice, but doesn't really do anything for you. The reason is that they don't come really sharp. Yes, they will drill holes, but so much better after using the Drill Doctor. Once they are sharpened, the thin coating is gone from the tip. Now, if you spent $220 for a full set, they'd not only be tougher metal but would come sharp. For wood, however, the cheaper set has lasted for years.

I went looking at grinder prices..Lowes Delta $129 nice one...but I don't
want to spend that kind of money...so off to HF I went and they had a combo unit 8" wet and 6"dry grinder for $60 bucks...sold got it home and pluged it in..turns on and the checkout lady threw in the extended warranty 15 months for free $6 buck saving their...so I"m happy for now...I've got some oil stones for my chisels and a guide for them also...I"ve sharpened sanding files (made a chisel on one end of it) on the grinding wheel where I use to work for trimming edge banding after it came thru the machine...it worked nice...so I'll have to teach myself the drill angles...practice..practice..and do it some more..........

Some can do it well, and they may also sharpen chisels without a guide. IMO,
"learning" how to do it is only half the issue. For bits smaller than 1/4, it gets more difficult, and there the Drill Doctor does a nice job. It's also much faster (at least for me) when you have many to sharpen. I've never been able to sharpen a chisel well without some kind of guide, although I can cut dovetails with a saw pretty much by eye. I still remember one machine shop where one old guy did all the sharpening, by eye and faster and better than anybody else. He tried teaching me, but I never made it.

First, you can grind your twist drill bits more safely on the belt than the grinding wheel due to less heat being generated by the belt. Second, you can sand edges of woodworking pieces on the belt. My Delta 31-080 (_Black_ model, Keeter) sander is probably the most used of any of my powah tools. Find one for ~$85 at tool stores or $30 on sale at HF (without the disc, $60 with) or less when they're on sale. Alternatively, build one yourself. It's not hard. 135k links: http://www.google.com/search?q=build+belt+sander - Yea, though I walk through the valley of Minwax, I shall stain no Cherry. http://diversify.com I moved to the 1-inch belt sander awhile ago. Don't use it for drill bits, but I built a sliding guide with different angles and it's the fastest way I've found for chisels and planes. I take nicks out on the ginder, then use the belt to restore the bevel and sharpen. Then just final honing on high grit flat paper. And by setting the angle ala Leonard Lee's book, it's the absolute best and fastest way to sharpen kitchen knives, leaving a nice tooth. That's the one tool I've bought that SWMBO really appreciates.

spake: Tina: Larry is right - and a belt grinder/sander is great for honing blades, carving tools etc... No, no, no! GRINDING, not honing. And if you don't yet know the difference, get Leonard Lee's book "The Complete Guide To Sharpening" I suppose you could use a leather belt on one and actually hone something, but that's purely overkill. Never contemplated of doing drill bits on mine. I'll try it. You can see mine set up below... http://woodwork.pmccl.com/Business/i...shop/shop.html It's easier on the 5" disc than the belt due to belt layering, but it can be done if you hold it against the belt where it's not backed up by a guide. I use 120 grit belts most often. ---------------------------------------------------------- Please return Stewardess to her original upright position. -------------------------------------- http://www.diversify.com Tagline-based T-shirts! |

Exactly what I said, except for using a belt sander. Using a belt sander to sharpen drill bits seems odd. A belt can not be as accurate as a stone wheeled grinder. I've worked in and around many machine shops and never met a good machinist that sharpens bits on a belt. Dave I do mine on my grinder but the machinist that showed me how, showed me on his belt. Worked just fine. -- -Mike- |

For bits smaller than 1/4, it gets more difficult, and there the Drill Doctor does a nice job. It's also much faster (at least for me) when you have many to sharpen. I can get smaller than 1/4 but not an awful lot smaller. Nothing below an 1/8th, for sure. But - those bits are so cheap, you just buy new ones. They aren't even worth the time on a Drill DR, let alone the cost of a Drill DR. -- -Mike- |

Maybe that's why you never met one, either. ---------------------------------------------------------- Please return Stewardess to her original upright position. -------------------------------------- http://www.diversify.com Tagline-based T-shirts! |

Don't know about the machine shops you've been in but like I said the guy who showed me how to sharpen drill bits showed me on a Stationary Belt Sander. Come to think of it, I've seen them in other machine shops as well. Maybe Larry just never noticed them in the shops he was in. -- -Mike- |

![]() I went looking at grinder prices..Lowes Delta $129 nice one...but I don't want to spend that kind of money...so off to HF I went and they had a combo unit 8" wet and 6"dry grinder for $60 bucks...sold got it home and pluged it in..turns on and the checkout lady threw in the extended warranty 15 months for free $6 buck saving their...so I"m happy for now...I've got some oil stones for my chisels and a guide for them also...I"ve sharpened sanding files (made a chisel on one end of it) on the grinding wheel where I use to work for trimming edge banding after it came thru the machine...it worked nice...so I'll have to teach myself the drill angles...practice..practice..and do it some more.......... Tina I suppose you bought this yellow one? http://www.harborfreight.com/cpi/cta...emnumber=35098 I think that should be a good economical purchase, everything else with a major name brand is made in China anyway. Good going. But now, in order to sharpen bits easily you need a drill bit sharpening jig that will work with the smaller faster wheel. It is like this one in the link though I don't think I would get the Sears one, http://www.sears.com/ / tools / search: 00925292000 (for the idea of what they look like) General makes one that might be better and you could search: http://www.amazon.com/exec/obidos/tg...973910-5972627 Jig mounted, it holds the bit tip against the flat side of the wheel while you turn it manualy, though you might need a finer grit wheel. It's good to WOMEN into mechanics and woodworking, I always appreciate that... hope you keep to it! -- Alex cravdraa_at-yahoo_dot-com not my site: http://www.e-sword.net/ |

Next in line will be a lighted magnifiyer that I can put anywhere...my eyes are as sharp as they use to be when I was younger....thanks for all the help! Tina Tina - most likely you can master the simple technique of sharpening a bit with a little instruction and save yourself the cash for stuff like jigs, etc. that you really don't need. Try this... Take a nice new bit - maybe a 1/4 or somewhat larger. Something that is big enough to see well but it need not be a monster bit. Hold it in front of your grinding wheel - with the grinder shut off. Hold it so that the drill bit is in this sort of orientation... / In other words, it will point right and the back side should be lower than the point. Lay the point of the bit onto the grinder wheel and look at the contact point. You'll see that there is a definite contact surface that starts at the land of the bit. Make the bit lay flat on that contact area. Now, by simply raising your rear hand, observe how the bit remains in full contact with the grinder, but you are moving the contact surface toward the very point of the drill. Do this a few times, and observe that all you are doing is raising the rear of the bit. Develop a little muscle memory in this process. That action will sharpen one side of the bit. To sharpen the other side, reverse and repeat. Most people try to emulate a pencil sharpener, and that simply will not work. You are not trying to make a pencil point, you are sharpening two cutting edges on the end of the bit. It's a lot easier to do than it is to explain. Again - before you buy anything, do yourself the favor of going to a machine shop and ask the machinist to show you how to do it. You'll be surprised at how easy it is to do. -- -Mike- |
