Short Drill Bits And Bits Smaller Than 1/8; Masonry Drill Bits - DRILL DOCTOR 500X Mode D'emploi

Bits 1/2" or larger will need a minimum of 40 half turns. A
3/4" bit may require up to 60 half turns. It may take two
or three complete sharpenings (repeat all steps) to re-
sharpen a very dull or chipped large drill bit.

Sharpening Wheel. If you regularly sharpen larger bits
between 1/2" and 3/4", you may wish to purchase the
coarser 100-grit Diamond Sharpening Wheel, which
sharpens larger bits faster.

Short Drill Bits and Bits Smaller than 1/8"

Set the point angle for 118°. Put the bit into the Chuck as
normal, but tighten Chuck so that it is just snug enough
for the bit to move freely. Push and hold the Alignment
Button. Partially insert the Chuck into the Alignment
Port, but do not push the Chuck all the way in. Use the
Chuck Knob to rotate the bit until it can be held by the Bit
Clamp Arms in the narrowest width of the bit. Make sure
that the bit is touching the Drill Stop, and then release the
Alignment Button. Turn the Chuck until the Alignment
Guide on the Chuck aligns with the 118º notch on the
Alignment Port. Now, push the Chuck in the rest of the
way. Tighten the Chuck, remove, and tighten again.
Sharpen the small bit as usual.
Aligning and Sharpening Masonry Drill Bits
To sharpen a masonry bit, you do not turn the Chuck.
Instead you insert the Chuck until it touches the wheel,
remove, and repeat on the other side.
