4PCS SET CAT 40 3/4 x 1.75" End Mill Tool Holder Balanced G2.5 20000RPM CAT40 Fits on Haas, Fadal, Mazak, Mori Seiki, Kitamura, Hurco Specification: Type: CAT40 Material: 40CR Bore Diameter: 3/4" Projection Length: 1.75” Max RPM Balanced To: G2.5 20000 RPM TIR (Inch): 0.0001” Drawbar Thread Size: 5/8"-11 Noes Diameter: 1.75" Coolant Thru: Yes Quantity: 4 pieces Feature: 1、Tool holder is balanced to G2.5 20,000 RPM. Balanced tool holder minimizes the centrifugal forces which minimize the stress on spindle bearing, minimize vibration and maximize the cutting tool's life cycle and greatly improve surface finish. 2、Unique design feature in the extension nose to minimize the off-balance nature of CAT 40 taper specification. On the side of flange where a half spherical hole is located, a flat is cut into the cylinder nose to compensate the weight of the metal chips lost from forming this spherical hole. And when the holder is placed into the Haimer balance machine, less holes would need to be drilled in the v groove of the flange to protect the rigidity of the tool holder. Evenly weight distribution will minimize centrifugal force in high speed spinning and thus maximize the holder's ability to hold the cutting tool concentric to spindle rotation. 3、All critical surface are precision ground 4、Internal bore concentricity is less than 0.0001" from taper to end mill pocket 5、Flange and V-groove are precision ground to ensure reliable tool change 6、Coolant thru spindle capability 4 x CAT40 3/4" x 1.75" End Mill Tool Holder CCCBD8328 We have other holders & collet chucks & pull stud available at my ebay store!
