Re: [AFMUG] Sharpening Drill Bits
The drill doctor has a masonry bit mode. Although, I don't think they
need a super-sharp edge to work. It's like they mainly just beat there
way through the material.

The downside is they are really poor at going through wood or any
material other than masonry, you need to switch to a regular bit for that.
Even in a hammer drill, you are probably using carbide tip bits, just
not SDS shank.

Re: [AFMUG] Sharpening Drill Bits
Once upon a time, I was in a vo-tec program for tool and die makers that was a feeder school for Boeing. One of our first subjects to study were twist drills. There are multiple faces on a twist drill as relief areas called the rake. Moreover the angle of the point varies with the material. The harder the material the less pointed the point. We had to make these things by hand and were graded by an optical comparator. Machineries handbook is a good source of info for stuff like this. Pointy drills are for wood. Not so pointy are for metal. From: Josh Reynolds Sent: Wednesday, June 03, 2015 6:36 PM To: af@afmug.com Subject: Re: [AFMUG] Sharpening Drill Bits It's funny to find this discussion on the list today, we have been talking about our drill doctor since this morning. We use a lot of 5/8x18 Irwin installer bits. We like them because they are reasonably priced, long enough to get through most of the log cabins here, and come with a 90deg angle point as opposed to the more common 118deg angle point. We run them into the ground though, which sucks the next time you have to drill through thinner wood siding or shingles because it will often split the wood on the exit hole, so you have to keep them sharp. We have a drill doctor, but it just does the 118deg angle which doesn't bite as well. Spent part of the day looking for a drill doctor with a 90deg or better angle, but it seems they don't make one. We'd probably be better off buying a table grinding wheel and a drill bit jig, but that can get spendy. Our end result decision is to just buy a crap ton of irwin bits. If anybody has a source for these, we'd like to buy in bulk at cheaper than $11/bit (local pricing).

I avoid the list after drinking, that used to result in offlist spankings. The tapered bits i should have clarified were the ones for a regular drill, i hate that the one ring always dulls out.

Re: [AFMUG] Sharpening Drill Bits
It's funny to find this discussion on the list today, we have been talking about our drill doctor since this morning. We use a lot of 5/8x18 Irwin installer bits. We like them because they are reasonably priced, long enough to get through most of the log cabins here, and come with a 90deg angle point as opposed to the more common 118deg angle point. We run them into the ground though, which sucks the next time you have to drill through thinner wood siding or shingles because it will often split the wood on the exit hole, so you have to keep them sharp. We have a drill doctor, but it just does the 118deg angle which doesn't bite as well. Spent part of the day looking for a drill doctor with a 90deg or better angle, but it seems they don't make one. We'd probably be better off buying a table grinding wheel and a drill bit jig, but that can get spendy. Our end result decision is to just buy a crap ton of irwin bits. If anybody has a source for these, we'd like to buy in bulk at cheaper than $11/bit (local pricing).

Re: [AFMUG] Sharpening Drill Bits
What you want for the concrete is a rotary hammer. A little spendy and the bit cost is astronomical, but they will bite through granite like it's nothing in seconds. We use rotary hammers for rohn wall mount kits going into brick, concrete, and stone. Have only tried the corded hitachi's, although dewalt has a cordless one I've been keeping my eye on. http://www.amazon.com/Hitachi-DH40MRY-16-inch-Rotary-Hammer/dp/B000XVINQY/ref=sr_1_4?ie=UTF8qid=1433378353sr=8-4keywords=hitachi+rotary+hammer is what we've used. http://www.amazon.com/DEWALT-DCH253M2-Mode-Rotary-Hammer/dp/B00DD1UOTU/ref=sr_1_9?ie=UTF8qid=1433378421sr=8-9keywords=dewalt+rotary+hammer is the one I've had my eye on.
