Anti-galling process creates a
super finish which increases the
life of both the drill and the
Steel: Our bushings are manufactured
from either C1144 Stress proof
steel or other high carbon steels
known for their long wear and
stability. Special materials such
as tungsten carbide, 52100 steel,
300 & 400 series stainless
steel, plus A2, D2, D3, M2, and
M4 tool steels and bronze are
Our bushings feature a two-directional
undercut and are ground square
to allow the bushings to fit flush
on top of the jig.
Our bushing feature an inside
chamfer which improves chip control
and reduces tool wear.
Blended radius at drill entrance
improves proper drill entry and
alignment which prevents tool
wear and breakage.
Hardness: Bushings are heat treated
to Rockwell C62-64.
For quick and proper identification,
all bushings are clearly stamped
with SIZE and TRADEMARK.
7. Slip fixed renewable (SF) bushing
heads are knurled which improves
operator handling when installing
and removing bushing from jigs
8. Chamfers on the O.D. exit end
of our bushings eliminate peening
which permits easy entry and removal.
