Product Features

Remarks

‎• HPT†- High Performance Tap†- DIN Length• Recommended for steels, steel alloys, stainless steels, titanium alloys and a wide variety of materials up to 36Rc hardness.• Spiral Flute Taps are 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.• 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 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 the work piece.• P/M Powder Metallurgy High Speed SteelPremium Steel Engineered For: Hardness / Wear Resistance / Tool Life / Heat Resistance / Toughness and Strength / Performance under Difficult Cutting Conditions / Higher Cutting Speeds / Increased Productivity
