Solid Carbide Drills
General Application Instructions

Toolholding Systems

As with any drilling system, components of the entire system contribute to the quality of the machined hole, not just the drill itself.
For maximum effi ciency and accuracy, the following toolholding systems are your best choices:

First Choice Second Choice Third Choice
Hydraulic chucks Shrink Fit High-performance milling chucks
with reduction sleeves

Not Recommended Clamping Chuck Highly Recommended
Use of all-purpose drilling chuck collets, Hydraulic chucks ensure a secure torque
®
clamping sleeves, and Weldon clamping transmission with excellent concentricity.
chucks should be avoided because they
do not absorb cutting forces reliably and
provide insuffi cient precision of concentricity.

[

Not Recommended Machine Rigid Machine Tool Recommended
Solid carbide drills have a much higher rigidity
than conventional high-speed steel drills. This
enables the machining of close-tolerance holes
with a position accuracy of ±.001". However,
it also means that drills require rigid machine
tools with good spindles.
