65\ Shoulder x .495"
These cutters are specially designed by us and made to our
specifications for cutting the sight base slot required to mount the
Wichita and Novak Lo-Mount 1911 Auto sights.
Use ¼" carbide end mill to remove the bulk of the material
drawing above) then make final dovetail cut. Final cut to lower rear
of slide is done with an end mill and is not a part of the sight base
cut. Made slightly undersized to compensate for variations in sight
bases and milling tolerances on installation. With the popularity of
custom 1911 Auto Pistols, this cutter is one that you will use
frequently in your custom work. CAUTION: For use in milling
machine only. 2" (5cm). .495" diameter cut. ½" (12.7mm) diameter shank. 65° shoulder. DO NOT EXCEED 700 rpm, HIGHER SPEED WILL BREAK TEETH.
