I see these on sale at Sears: Are they any good or a waste of money? I usually buy new drill bits and throw the dull ones out.... o No: - Bill
I use my drill bits ALOT! This was the best money I have spent for a usefull tool! I highly recommend the Drill Doctor! It sharpens them as good as new, and I like the way you can sharpen them with the quad cut tip..... real nice! I thin I have sharpened 100 or so bits already....some many times. It's saved me alot of money! Mike :TU:
yeah im with Mike, buy it you wont be sorry. it is a very useful tool. then if you buy one you can get good drill bits and sharpen them many times and they are like new after sharpening.
I was wondering the same thing.Recently a couple of co-workers and I stopped at my moms garage and we was looking at the tools my dad passed on to me when he passed away and there was a brand new in the box drill doctor.One of the guys family has a farm and said they use theirs alot and can't be without one.I told him I didn't even know I had one till then.Guess I'll have to dull some bits to find out.My dad was a mechanic by trade and has a Snap-on 1 1/2 tool box drawer filled with bits plus 3 of the index sets.I can't see me ever running out. BTW...Does anyone know were to buy empty drill indexes? I have tried Sears and lots of places but haven't been able to just buy the indexes they want to sell you them with the bits. Pat
I used to have a black and decker bit sharpener but it did a lousy job so I just learned to do this myself. I sharpen my bits on a grinding wheel. It took a lot of practice, but when you understand the angles it's really easy. The trick is to slowly twist in the direction of rotation as you hold it at an angle to the grinding wheel, one side at a time, and make sure both cutting edges end up about equal. If you look closely at a large bit, like say a 1/2", notice the angles and how it's ground. Smaller bits are ground the same but are just harder to see. I never throw away a bit unless it's too short to use. :bglasses:
Last week I saw an infomercial and it seemed like something to get. But not now, as i dont do enough work to justify having one. If i ended up getting one it wouldn't be the cheapest one, probably the 300. I think they all have the diamond grinding wheels. I have yet to try it. But sounds like a good investment.
next time you buys drills, buy nothing but cobalt drills. they are stronger and last longer are next best drill to carbide for drilling tough material. hss, high speed drills are useless. also, if you can find them, buy some centerdrills. great for starting holes. matter of fact, any drilling, milling, tapping always get cobalt. john
