Left handed drill bits
I have a few left handed drill bits. I use thes exclusively for
extracting broken bolts. I was wondering if this is the only purpose for which they were intended. Jimmie |

I used to sharpen some broken bits backward and paint them yellow just for this purpose. The colour was only a way to recognize them in the drawer quickly. They worked great when needed. Why would they have to have multi uses anyway? This one use was a real enough time saver when needed. |

Jimmie They're good for use by left-handed people with left-handed drills. But I guess I only use tthem for extracting specialty screws and broken bolts. The first time I tried to buy these things, at least one hardware guy thought I was kidding. He didn't have left-handed nails, either. |

Jimmie Commonly used when hand drilling out damaged right hand threads in soft metals so that the drill doesn't seize and kick back taking your knuckles with it. The drill is usually sharpened with very little rake as well. No that's not a grass rake, you humorists. Jioe |

Jimmie No, we used to use them frequently on the old Brown and Sharpe screw machines. Those were the original automatic lathes, originally developed around the turn of the century (not the most recent one!) for, uh, making screws. On a lathe, the spindle turns the stock, and the drill is fixed - it doesn't rotate. So if you have an operation where you want or need the spindle rotating backwards, you need a backwards (left-handed) drill. |

I suppose to remove a bolt you don't want it generating piles of metal and drilling into the bolt, anyway - all it needs to do is bite and draw the bolt out. Maybe I'll give it a try - I think I've got a few broken bits somewhere. Always wondered if there's a good reason why normal bits drill in the same direction as screw threads, or whether it's it just cooincidence... cheers Jules |

I'd guess that a left ground right bit would scrape, rather
than drill. I can't imagine it being at all useful. -- Christopher A. Young Learn more about Jesus www.lds.org .. "jeff_wisnia" wrote in message eonecommunications...

I was sharpening some drill bits I got in a junk store and couldn't
figure out why I couldn't get right. Yep it's a 3/8 " left hand, so I stand backwards when I use it. There are " Left hand crescent wrenches ! I do own one. it's funny when I lend it to some one that is working under a car , the dam thing drives you nuts. I used to throw it across the yard until I got used to turning the barrow back wards Jerry |

I learned to sharpen bits by hand many years ago from an old machinist. This is something he showed me before I had ever seen a left twist bit. |

Jeff The bit is only intended to catch hold of the broken bolt with a reversible drill motor and twist the broken bolt out of the hole. The flute at the end is ground to cut at a low angle to catch the bolt and remove it. You can drill a small pilot hole in the center of a stubborn bolt for the left hand sharpened tip to catch. Done it for years prior to retiring. Use the method still if needed. Don't need it as often, that's all. |

Done it for years prior to retiring. Use the method still if needed. Don't need it as often, that's all. If need be I have three different styles of easy outs. The long twist with a tap wrench end, square easy outs with cut edges to catch and short ones with many edges that have hex heads to turn them out. The reverse drill bit is a first try and quickest. Snap-On and Mac carry them all if you care to look the styles of easy outs up. |

Jeff -- Jeffry Wisnia (W1BSV + Brass Rat '57 EE) The speed of light is 1.8*10e12 furlongs per fortnight. Left hand drills have left twist to remove chips. There are router bits and CNC bits, however, that are 'downcutting' so that chips are kept away from the surface for specialized reasons. Joe |
