2-1/8" OVERALL LENGTH
TiN COATING
ShearTap for Stainless Steel & Carbon Steel up to 35Rc hardness.
CNC Style enchances 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 Style is designed to lift the chips out of the hole in blind hole tapping, eliminating chip evacuation problems which can result in damaged threads and broken taps. They will also bridge openings, keyways and other interruptions in the tapped hole.
TiN Coating - Titanium Nitride increases wear resistance, reduces friction and galling, reduces tapping torque, improves thread quality, and allows increased cutting speeds. Productivity and tool life are improved.
