The Drill Doctor
The sharpening process includes 3 easy steps:
1. Align the bit in the Chuck.
2. Sharpen the bit (until there is no more grinding noise).
3. Split the point (optional on 118°, mandatory on 135°).
Be sure to complete each step to sharpen and split a bit and
always sharpen the bit prior to splitting it.

Standard Point
This general-purpose point (normally
118°) is used for drilling softer materials
like cold rolled steel, aluminum, and

Split-point bits (normally 135°) are
generally used for drilling into harder
materials, like tempered steels, hard
alloys or hard cast materials.
Masonry Bits
Masonry bits have a carbide insert
at the point and are used for drilling
materials like cement, brick, and
ceramic.
