Collets for Auto-Reversing Tapping Heads
Secure taps in auto-reversing tapping heads with these collets. They hold inch and metric taps with shanks that meet ANSI standards.
Collets for Tapmatic and for McMaster-Carr approved tapping heads are made of rubber that compresses to hold a range of tap sizes. Steel jaw inserts add strength and maintain grip as these collets squeeze the tap shank.
