Starrett - Protractors

This is a special gage that makes it possible to accurately and quickly determine correct clearance angles for maximum in cutter efficiency.

Benefits

• Eliminates guesswork and elaborate gaging equipment
• Highly versatile – this tool will measure clearance angles up to 30° on helical, straight, side or inserted tooth milling cutters, straight or helical end mills, T-slot cutters, metal cutting saws, and broaches
• Can be used on cutters from 2-30" (50-760 mm) diameter and also on cutters and end mills from 1/2-2" (12.7-50 mm) if teeth are evenly spaced
• Hardened for long life

Use

• This gage is made of the finest tool steel, hardened for long life, and is extremely easy to use. It consists of a frame graduated from 0-30° and having a fixed foot, an adjustable sliding foot on the beam extension of the frame, and a blade which is adjustable angularly and perpendicularly to contact the clearance angle of any cutter tooth
• To use the gage, the feet are positioned on two alternate teeth of the cutter with the gage at right angles to the cutter axis and the adjustable blade, which is set at the correct clearance angle. This shows at a glance when the cutter tooth is ground to the desired angle (see photo)
