Semi-bottoming style (2-3 thread chamfer) allows threading close to the bottom of blind holes but cuts more efficiently than standard bottoming taps due to a slightly longer chamfer which distributes the cutting load over a greater number of teeth
Powder metallurgy high speed steel premium steel engineered for hardness, wear resistance, tool, heat resistance, toughness and strength, performance under difficult cutting conditions, higher cutting speeds, increased productivity
Titanium carbonitride coating increases wear resistance, reduces friction and galling, reduces tapping torque, improves thread quality and allows increased cutting speeds for greatly increased productivity and tool life
