CNC CAT40 End Mill Holder DIN Coolant Through Flange 7/8 In X 3.50 In, 20K RPM Balanced,.0002 In TIR, Forged Construction, ANSI Compliant, GS Tooling

CAT40 End Mill Holder DIN Coolant Through 7/8x3.50 in, 1 Pc
✔️ 20,000 RPM balanced,.0002 in TIR, ANSI forged, coolant flange

The CNC CAT40 end mill holder is a precision toolholding accessory used on CNC milling centers to secure cutting tools in CAT40 spindles. The DIN coolant-through flange enables coolant to reach the tool tip for better chip control and longer tool life. Shank traverse ground design ensures maximum accuracy, and the entire body is 100% forged for strength. It meets ANSI specifications and is factory balanced to reduce spindle wear at speeds up to 20,000 RPM. Each holder includes an inspection lab report for quality assurance. Dimensions: shank 7/8 in (22.23 mm) and length 3.50 in (88.90 mm).
