For fast, easy drill sharpening
body. To prevent personal injury and/or damage to the drill, ALWAYS keep drills in protected area.
Here's a unit that really makes drill sharpening easy. All you do is place the hollow drill in the tapered
end of the drill holder, insert the unit on the cylinder, then turn two or three times...and you have a
perfectly sharpened drill.
This Challenge Hollow Drill Sharpener can pay for itself many times over through longer drill life, eas-
ier, faster drilling, and less sharpening time. All sizes of drills from 1/8 to 1/2 inch in diameter can be
sharpened.
The drill sharpener automatically puts just the right amount of bevel on the hollow drill for the best
drilling results. It's self-centering, too, so that the center of the sharpening bit exactly meets the cen-
ter of the hollow drill. The drill sharpener also has a replaceable sharpening bit.
