ShearTapô ShearTapô -for Stainless Steel & Carbon Steel up to 35Rc hardness. Oversize taps are mainly used for parts that will be plated or heat treated after tapping. Also used in materials that tend to shrink after tapping. CNC Styleenchances chip evacuation and cutting fluid flow to the cutting teeth for reduced friction, heat and galling. Also reduces contact between the tap and the workpiece. Semi-Bottoming Styleare designed to lift the chips sout of the hole in blind hole tapping, eliminating chip evacuation problems which can result in damaged threads and broken taps. They will also bridge opeings, keyways and other interruptions in the tapped hole. TiN Coating - Titanium Nitrideincreases wear resistance, reduces firiction and galling, reduces tapping torque, improves thread quality, and allows increased cutting speeds. Productivity and tool life are improved.Country of OriginUSAWarning-Proposition 65- For Californian Users onlyWARNING: This product contains a chemical known to the State of California to cause cancer or Birth defects.
