930 Series

Tool 931i2018B

Sharp corners chip when interrupted cuts hit workholding fixtures. The 931i2018B handles 5/16" dovetail profiles in steel and aluminum with a 0.01" corner radius that extends tool life in demanding workholding applications.

Three flutes balance finish quality with chip evacuation in the confined geometry of dovetail cutting.
The 45-degree included angle matches standard workholding requirements while the 0.1772" neck diameter provides clearance in restricted access situations.
AlTiN coating handles the heat generated in steel applications where dovetail mills typically see interrupted cutting conditions.
The coating maintains edge sharpness longer than uncoated tools when cutting through bolt holes and other features common in workholding setups.
The corner radius eliminates the stress concentration point that causes premature failure in both the cutting edge and the finished dovetail profile.
