<strong>microscope</strong><br />
New Family of Micro Single Ended Tools<br />
The Microscope line offers new and improved solutions for micro grooving,<br />
boring and threading in bores as small as .04 inches.<br />
The Microscope line offers a large range of new single-ended inserts and a full<br />
range of tool holders with a simple clamping system.<br />
See it in action<br />
Improved Coolant Thru<br />
Two coolant holes for effective chip<br />
removal and cooling of cutting edge<br />
New Slanted Insert Design<br />
Provides exact insert location for<br />
high repeatability<br />
Simple Clamping System<br />
Simple and fool-proof, the new clamping<br />
system uses one large screw to secure the<br />
insert in the holder<br />
Applications<br />
Grooving<br />
Boring<br />
Stopper Pin<br />
Provides precise cutting<br />
edge height and perfect<br />
axial location<br />
