Morse 5/16-24 Tap HSSPM Spiral Point Plug Tap CrN Coated CNC Reduced Neck 6pk

• HPT†- High Performance Tap - Aluminum• Recommended for all types of aluminum alloys. CrN coating especially recommended for high-silicon aluminum alloys.• Spiral†Point Taps are designed fo refficient 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 evacuation problems and chip damage to the threads. Shallower flutes also result in greater tap strength, allowing for higher cutting speeds.• Semi-Interrupted Thread (3-Flute taps only)• 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.• 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 / Heat Resistance / Toughness and Strength / Performance under Difficult Cutting Conditions / Higher Cutting Speeds / Increased Productivity
