Titanium Drills?
Just got a NorthernTools e mail with a titanium drill set for $42 for a 115
piece set. What do you think of Titanium drill bits? Or maybe I need a sharpener for the hundreds of dull bits I already have ................... Steve |

However, if the bits are poor steel anyway, then they are not of much use. There may be some benefit in better chip clearing. Learning how to sharpen drillbits is good. -- http://inquisitor.i.am/ | | Ian Stirling. ---------------------------+-------------------------+-------------------------- Two parrots sitting on a perch.

Those sets are all over ebay. You can get them for about 20-25 bucks.

Harbor Freight has regular Black Oxide bits n sale now, 115 piece set for about $24.00, which should do just fine in most home shops for the average guy. I sort of like the HF bits and other import, as they do seem harder than some american made ones. The biggest problems I found with the ones that did not drill right was that they were not sharpened right, and other than that, they seem to hold up just fine. I have heard that the Chinese use cyrogenic treating on their drillbits. Well, I have that set of HF bits. I was drilling a 1/2 inch hole in some diamond plate on my truck, and suddenly the drill motor (a Hole Hawg) started to free spin. I stopped the drill motor and the bit had a reduced round shank about a half inch long at the end of the bit. The flutes had sheared free of the drill body for half an inch from the tip. Now that's crappy metallurgy. I had never seen a bit fail that way before. I went and got a good Cleveland Twist Drill bit, and it breezed through the rest of the holes with no problem. Gary |

I got a laughing in my hat e-mail with that in it -
the drills are coated - if they were solid stuff they would likely twist if ever slightly jammed. The coating is just to help reduce wear with hard materials. Doesn't say as to the quality at all. A chunk of lead can be Ti coated. Martin -- Martin Eastburn, Barbara Eastburn @ home at Lion's Lair with our computer NRA LOH, NRA Life NRA Second Amendment Task Force Charter Founder |
