We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.AT3 or BetterTaper ground to AT3 or better ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerancePilot ContactInside bore are precision turned to engage a better contact with retention knob’s pilot to increase rigidityTaper End FacePrecision turning surface finish provide perpendicular contact with the flange of retention knob to increase rigidityPre-Balance DesignUnique 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.Dynamic BalancingTool holder is balanced to G2.5 20,000 RPM on a HAIMER Tool Dynamic Balancing System from Germany. 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. TIR from taper to end mill pocket is less than 0.0001″ Each holder comes with a lab certificate on its balancing dataFlange and V-groove are precision ground to ensure reliable tool changeSpindle Thru coolant capability Product includesBalancing certificate Related products(Click the link to the item page)Product Code: 202-5925 CAT 40 5/8-11 45 Pull Stud Retention Knob for Haas Kitamura MiyanoProduct Code: 202-5927 CAT 40 Coolant Thru 45 Pull Stud Retention Knob For Fadal Mazak Hurco TreeProduct Code: 202-5928 CAT 40 5/8-11 45 Pull Stud Retention Knob For Fadal Mazak Hurco TreeProduct Code: 202-5944（5） 5pcs CAT 40 45 0.589 Pull Stud Coolant Thru Retention Knob for Haas MachineProduct Code: 202-6290 CAT 40 15 0.747 Pull Stud Coolant Thru Retention Knob for DMG Mori DoosanWe have other holders & collet chucks available at My Ebay Store: If you need to speak to a sales person feel free to call.
