Sharpening Process
The sharpening process includes 4 easy procedures:
1.
Determine the type and angle of the drill bit.
2.
Align the bit in the Chuck.
3.
Sharpen the bit.
4.
Split the point (if you choose).
Be sure to complete the first three procedures in
order to sharpen a bit; and always sharpen a bit prior
to splitting it.
On the Model 500X
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. If you
can’t tell due to small size or
damage on the tip, set your
Drill Doctor based on the
application. Most wood and
soft metal applications
require 118°. Harder materi-
als such as stainless steel
and tool steel require 135°. If
you are drilling contoured materials (such a car fender),
plan on splitting the point.
Choosing Your Drill Bit Point Angle
When drilling into certain difficult materials, a shallower
point or 135° point angle produces a better-finished hole.
Your Drill Doctor allows you to sharpen bits with either
the standard 118° or the flatter 135° point angle. You can
also adjust the “chisel and relief angle.” (Refer to page 23
for the benefits of using Variable Alignment to adjust the
Chisel and Relief angles.)
Depending on the material you are drilling in, you may
choose to increase or decrease these angles.
