Accusize R8 Shank ER16 Collet Chuck, 7/16''-20 Drawbar End, 0223-0229

Key features

• PRECISION COLLET HOLDING WITH R8 SHANK: Mount ER16 collets with a maximum TIR of 0.0002in for tight-tolerance turning, milling, and finishing operations where runout directly affects surface quality and dimensional accuracy
• ALLOY STEEL BODY HARDENED TO HRC 52-56: The all-ground construction maintains concentricity under repeated clamping cycles, resisting deformation at full torque so the chuck holds collets securely without losing alignment over extended production runs
• RATED FOR 8000RPM ACROSS ROUGHING AND FINISHING: Balanced for high-speed operation so you can push feed rates during roughing and still achieve fine surface finishes at speed, without vibration or chatter compromising the cut
• QUICK COLLET CHANGES WITH STANDARD ER DESIGN: The industry-standard ER taper lets you swap collet sizes in seconds using a standard wrench, keeping downtime short between operations and eliminating the need for proprietary tooling
• FOR MILLING, TURNING, DRILLING AND TAPPING WORK: Serving the metalworking community from Canada since 2008, this line provides reliable workholding tools for professional machinists and dedicated hobbyists, delivering dependable precision at a practical price
