2 ShearTap TM HIGH PRODUCTION TAPS Premium High Speed Steel H I G H V O L U M E P R O D U C T I O N T A P P I N G CARBON STEELS STAINLESS STEELS ShearTap TM offers exceptional value for high volume production tapping in carbon steels and stainless steels up to 35Rc hardness. ShearTap TM features a new optimized flute design for tremendous cutting edge strength and wear resistance, fast chip removal and perfect quality threads. A reduced neck and shorter thread length allow for deeper hole tapping while enhancing coolant flow to the cutting teeth for extended tool life. GEOMETRY Spiral Point Taps are designed for efficient tapping of through holes and blind holes with adequate depth for chip accumulation at the bottom of the hole. The shearing action of the point provides freer cutting action and ejects the chips ahead of the tap, eliminating chip disposal problems and chip damage to the threads. Shallower flutes also result in greater tap strength allowing for higher cutting speeds. Spiral Flute Taps are designed to lift the chips out of the hole in blind hole tapping, eliminating chip disposal problems which can result in damaged threads and broken taps. They will also bridge openings, keyways and other interruptions in the tapped hole. Plug Style (3-5 thread chamfer) is the most common chamfer used for tapping applications in through holes and blind holes with sufficient bottom clearance. Modified Bottoming Style (2-2-1/2 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. CNC Reduced Neck Design enhances chip evacuation and cutting fluid flow to the cutting teeth for reduced friction, heat and galling. Also reduces contact between the tap and the work piece. SURFACE FINISHES / TOOL COATINGS Steam Oxide Over Nitride Finish helps toughen the hard abrasion resistant nitrided base. Also reduces friction, loading and galling, helps retain cutting fluids, improves thread quality and extends tool life. - Titanium Nitride 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. 2
