Cuts the .250" x 74° dovetail required when altering ramp-style front sights to accept Meprolight's Universal front sight inserts. Cutter can be used to open up a standard ramp when installing Brownells Colored Sight Inserts. DO NOT EXCEED 700 RPM. HIGHER SPEED WILL BREAK TEETH.

I would not buy this cutter(19/03/2012)
cutter has a por back relief and causes chips to bunch up and break the bit.
Poorly engineered(04/10/2012)
Agree with previous review about the back cut to expel chips. Also recommend manufacturer publish more specific speeds and feeds for different materials. 700 rpm @3ipm on cnc is insufficient for this cutter. would recommend at least double the speed, half the feed. Unfortunately Brownells is the only supplier of this tool!
