Solid Carbide Drill for high accuracy
MHE
y Outline
For machining bolt holes of hubs, general-purpose drills are widely used, but are not highly productive due to the
following problems.
a Elongated chips damage the periphery of the holes and lead to poor surface finishes.
a Plastic deformation can occur leading to a work hardened layer in the wall of the hole. This can result in a
poor press fitting of the hub bolts.
a Due to the poor surface finish, a reaming operation maybe required to finish the holes.
MHE solid carbide drills overcome the above problems with excellent chip control and offer efficient, high
precision drilling due to the use of low resistance cutting edges and a low helix angle.
