The shiny edges to the left, pointed to with green arrows, are actual
dressed edges from only a few strokes of this new drill bit sharpener.
The DrillGadget can easily put a knife sharp edge on the cutting edges
of both 118 degree drill bits and 135 degree drill bits as well as
maintain the very important chisel tip. And it does it all at the proper
rake angle as well, providing the relief angle all bits need. Note the
grinding marks from a motorized drill bit sharpener have been
removed with the DrillGadget, making the drill bit even sharper. This
drill tip geometry, or nomenclature, is crucial and must be maintained
by your drill bit sharpener for good drilling results.
The image on the left is a typical 118 degree drill bit. Images of 135
degree bits are shown on Actual Results page.

When drilling wood, you should see crisp shavings.
When drilling metal, you should see spiral chips. If
you're not, your drill bits are not sharp. Shown are
actual results from drill bits sharpened with the new
to the market pocket size manual drill bit sharpener,
the DrillGadget.

Drill bits just don't work if the geometry has been compromised.
