Drill press question
When I see a 9" or 12" or 15" drill press, what
exactly is that measurement? is that 9" (or other) the distance from the bottom of the table to the drill bit "chuck" or how deep of an item you can put into the drill press before it hits the "back/rear" post? email reply prefered (remove the _nospam ) Thanks for your help. |

Drill press question
It is the size of an object that you can drill to the center. For example,
a 12" drill press allows you to drill up to 6" from the column. Basically you take the 'size' and divide in half, and that gives you the depth from the chuck axis to the column.

Drill press question
Michael,
I grew up with the younger brother of a Mike Sutton in El Paso, Texas.... that wouldn;t be you would it? I agree with Paul. More important for me are number of speeds, stroke length, and whether or not the drill press has a quill lock. The quill lock is hard to come by any more, but it can;t be beat for setup operations. Larry -- Americans "Paul Kierstead" wrote in message news In article , (Doug Miller) wrote: or how deep of an item you can put into the drill press before it hits the "back/rear" post? yes Sorry, let me be more clear -- e.g. a 12" drill press measures 6" from the column to the center of the chuck, 15" DP measures 7.5", and so on. Just a word of warning based on my experience with a DP: Don't pay too much attention to the "Capacity" rating unless you really need it. I bought a 12" Delta DP thinking I usually am drilling near an edge anyway. Sure enough, I pretty much never hit the column and the odd time I did, some careful work with a hand drill did fine. But -- for me at least -- I found two other factos much much more important: - Minimum speed - Stroke After drilling 48 holes which all had to be double drilled 'cause my DP didn't have enough stroke and after having a couple of "incidents" with very large bits, I bought one with a lot more stroke and a lot lower minimum speed. And more capacity does not always equal more stroke; even the same capacity doesn't mean the same stroke. For example, Delta sells 2 different 16 1/2" presses which have a different stroke, even though they look very similiar. And some of the "larger" ones have less stroke the some of the smaller ones. And some real nice large ones have a pretty high minimum speed for very large bits. My DP was one of the few tools where I seriously regretted my balancing act between cost/performance (and failed to research the problem thoroughly). Especially since DP are one of the cheaper tools. I think I vastly underestimated its usefulness was part of the problem. BTW, if you don't need a lot of stroke, column space and a very low minimum speed, the Delta 12" is real nice. Very smooth and slick. |

I didn't think much about stroke...... I'll have to keep that in mind... I looked at a "Golden Hawk" (cal hawk) the other day, but I'm leary of "china-man" drill press. I found several negative reviews of them in inetrnet newsgroups. I think I'm going to spend the extra money and buy a better brand name such as Delta, etc. I'd like to find one of the "old" Craftsman ones at a garage sale. Their new ones don't seem to be as well made. Any advange of getting a "benchtop" or a "floor" model? I see the benchtop might take up some bench space, but what other advantages are for the "floor" model? |

Drill press question
I have an old delta with the over head bearing, one hell of a machine. Any
of the new delta machines I have seen are china made, I looked at one of those $300.00 Ridgit machines in Home Depot, I would rather have my 40 year old delta. |

I would rather have your old Delta too, but for those of us still out a DP the Rigid at Home Depot was given a second best in some woodworking book I read awhile back. And about a hundred bucks less. |

You'll have to go through the full line catalog to determine exactly which models are or aren't. Until you get into the so called production drill presses, there are none made in the US today. Spindle locks are a thing of the past, found mostly on older US made units, seems to be ignored on imports. Standard stroke for a floor model used to be 5", now it's 3". Sorry part is that what is now called "production" used to be about middle of the line workshop stuff. (Which makes me like my Crapsman [King-Seely] all the more. You won't find that quality at Wally's little chinese and slave markets.) |
