Your Drill Doctor® allows you to sharpen bits with either the
standard 118° or the atter 135° point angle. You can also adjust
the chisel and relief angle. (Refer to section “Adjust Chisel and
Relief Angles”.)
Depending on what you are drilling in, you may choose to increase
or decrease these angles.
On The Model DD500X
Check your drill bit angle
Most bits are 118° or 135°. Hold your
bit point up to the key to the left to see
which type your bit looks like. Most
wood and soft metal applications
require 118°. Harder materials such as
stainless steel and tool steel require
135°. If you are drilling contoured
materials (such a car fender), plan on
splitting the point to prevent walking
of the bit.
Choose the angle
Loosen the Point Angle Adjustment
Knob on the right side of the
Sharpening Port and slide the metal
Point Angle Adjustment Plate to
either the standard 118° or the atter
135° point angle. Then re-tighten the
Knob. The selected angle will show in
the small window on the plate.
