Thread: Drill Doctor and Small Bits ?

Hi all,

Does anyone here use a Drill Doctor ? I have the 500x, it is about 2 years old now, I bought it to re sharpen 2 drill bits that get a hammering (1/4" and 3/8") I install a lot of security systems, on the front doors when we put the reed switches in we drill a 3/8" hole for the reed and push it in. If I drill it on a very narrow angle ~30degree, It is just timber, but this looks ugly and should be filled and painted. I prefer to drill ~85degree through the lintel and into the inside brick. As soon as I go though the lintel the bit hits the cement and bricks and the edge has gone. So I use Colbolt 135 degree split point bits and re sharpen with no problems.

The problem I have is in aligning the 4.5mm and smaller bits, they seem to grab ok in the alignment jig, but once sharpened they seem dull still

I use 3mm alot in mounting card readers in lifts and these are Stainless panels.

I would prefer to sharpen these than throwing and buying more.

For the middle and larger sizes this works great, is easy to use for all bits (118 / 135 degree and split / no split point bits)


Any ideas ?

Kat.
