10-Pack CAT 40 15 .747 Pull Stud Coolant Thru Retention Knob Replacement for CNC Machining Machines

10-Pack CAT 40 15 .747 Pull Stud Coolant Thru Retention KnobDescription:Taper: CAT 40Head diameter(D1): 0.747"Head angle: 15-degreeDrawbar thread size: 5/8"-11Machine taper size: CAT40Neck diameter(D2): 0.549"Hole(D3): 0.281"Pilot(D4): 0.641"Overall length(L): 2.001"Shoulder to head(L1): 0.787"Shoulder to end(L2): 1.024"Coolant hole: YesFeature:Using high quality alloy steel 5155 forging, the material is metallographic dense, uniform and stable.After carburizing, the outside of material is hardened, and the inside of material is still soft and has enough toughness. Therefore, Material has higher wear resistance and better toughness.Precision grinding pull stubs have higher surface finish and dimension accuracy. The fitting accuracy is obviously higher than that of machine pull stubs, effectively reduces the error of machine tool and cooperation, so as to improve the accuracy and stability of the connection and improves the precision of the machine tools and lengthens the service life.Precision finished on the bottom of the flange to improve fitting with the bottom nose of the taper on the tool holder High quality black oxide finish can ensure long pull stub life.Package includes:10 x CAT 40 15 .747 Pull Stud Coolant Thru Retention Knob
