CAT40 C 1-1/4"-3.54" Multi-Lock Milling Chuck, Non-Coolant thru the flange

Taper Size: CAT40<br>Shank Type: Taper Shank<br>Hole Diameter (Decimal Inch): 1.25<br>Nose Diameter (Decimal Inch): 2.88<br>Projection (Decimal Inch): 3.54<br>Extreme Rigidity - The extra thick design assures a powerful clamping force capability, minimizing vibration and distortion. Long Life - Superior steel alloy allows tough hardening treatment for greater durability. Bore Slots - High accuracy and a very powerful gripping force is achieved evenly over the entire length of the chuck right down to the nose. This is generated by the long fine slots of the internal bore which is an integral part of the entire body. This design further assures accuracy by its self-centering operation. When the nut is firmly clamped, the greater the concentricity.<br>DIN coolant thru the flange at no extra charge<br>Rough milling or "hogging" operations<br>Improved tool life over regular end mill holders "360º" gripping contact<br>0.0002" TIR for maximum tool life and accuracy
