Overview
**All images are representative images. Verify specifications before placing orders.** All Techniks hydraulic chucks are precision balanced to 25,000 RPM @ G2.5 making them an excellent choice for machining with small diameter tools. HSK63A Hydraulic Holders SLIM line features narrower nose diameters for machining in tight areas such as mold & die work or whenever necessary to machine around obstructions such as workholding fixtures. SLIM chucks are available in a wide selection of on-size bores. The extended hydraulic bladder provides very stable clamping along the tool shank at have a repeatable accuracy of less than 0.0001” run-out making them an excellent choice for precision drilling and reaming applications. The EXTENDED line features longer gage lengths when long reach applications require the ultimate accuracy and stability such as when machining on horizontal machining centers. Narrow body design for better clearance Maximum T.IR. of 0.0001” at 3X diameter AD/B CoolFLEX coolant delivery standard
