Masonry drill bits

If all else fails, get two dogs and some rope.

Just wondering if anyone sharpens or has their masonry bits sharpened and any info / tips you may have? I install quite a few parking logs in concrete and dull Bosch bits are starting to accumulate.

thanks for the tips, i test drove my pug/chiwawa but the driver is still a little faster

What hammerdrill are you using (SDS or Spline?) Is it fully hammering as you drill? Personally, I have never had an issue with bits being "dull". I can usually drill them to death or until they break. Striking imbedded rebar will slow the drilling down (or even force your hole to shift if its a large enough bar)

I don't bother with sharpening masony bits. The cost of them is reasonable so as to just replace them as needed. Depending on how many holes you need to drill in the job, I always carry extras with me. The amount of downward force you are applying to the hammer drill, will directly affect the performance and lifespan of the bits! I find using mid-range speed and moderate bit force helps to relieve arm strain and helps extend the bit life. If going in deep, allow the bit to cool off frequently by pulling the bit out of your wall or ground surface for a few moments. Using heavy bit force will create a lot of heat on the bit and also could take the temper out of the carbide tip. You could see the heat damage by noticing a dark blue-ish coloring on the bit edge. Use moderate pressure again to do the job and just let the machine and bit "do their thing" normally to finish the holes.

Did you find out what the problem was?

Never sharpen the things and been using the same one for nine years.

In 6 years with SW, I got a a few free pails of paint when I first started buying from them. Never a visit or call from the rep. When SW had the bad batches of chlorinated rubber, my complaints fell on deaf ears. One of my competitors who buys about 10% more paint a year than I do, was compensated for the bad paint. Replacement of product, and money for lost labor. In 6 years with Glidden and Pittsburgh paint stores for Aexell product. Free paint to try new product. A few free spray tips, a few free lunches, decent discount on a machine. Delivery in some cases, when out on a job site. Have had a few visits from the rep, both on job site and a lunch from time to time. Oh, and a few t-shirts from time to time for the crew.

not yet been to busy to look at further
