Sandvik Coromant 8056458 Spiral Flute Tap M3x0.50

Product Description

The SANDVIK COROMANT 8056458 is a spiral flute tap designed for threading M3x0.50 holes to the JIS B 4430 standard. Built from High Speed Steel-E-PM (HSS-E-PM) with a TiAlN coating, this tap delivers extended tool life in steel applications where heat and abrasion resistance are critical. The semi-bottoming chamfer allows threading close to the bottom of blind holes without requiring a full bottoming tap. With a 48-degree helix angle, the spiral flutes evacuate chips upward and away from the cutting zone. Licensed machinists and CNC operators rely on this tap for precision threaded holes in production and job shop environments.

This tap is suited for tapping M3x0.50 right-hand threads in steel workpieces, including low to medium alloy steels classified under material grade P1PM. The semi-bottoming chamfer and 18 mm tapping depth make it effective in moderately deep blind hole applications. It is used in CNC machining centers, drill presses, and manual tapping setups where consistent thread quality and class 6HX fit tolerance are required. The T300 series designation places it within SANDVIK COROMANT's standard tooling range for threading operations.

Key Features

• M3x0.50 thread size to JIS B 4430 standard with 6HX class of fit for precise tolerance control
• TiAlN coating provides heat resistance and extended tool life in steel cutting applications
• High Speed Steel-E-PM (HSS-E-PM) substrate with material grade P1PM for toughness and wear resistance
• 48-degree helix angle promotes efficient upward chip evacuation in blind holes
• Semi-bottoming chamfer allows threading close to hole bottom in blind hole applications
• 3 right-hand spiral flutes with 18 mm maximum tapping depth

Compatibility

Designed as a direct-fit threading tool for M3x0.50 right-hand threaded holes in steel, conforming to JIS B 4430 thread standards with a 6HX tolerance class. No coolant-through capability; suited for external or flood coolant setups.

Installation Notes

This tap is installed by machinists and CNC operators in standard tap holders or floating tap chucks sized for the 4 mm shank diameter. Before use, verify spindle speed and feed rate are appropriate for the workpiece material and hole depth. Secure the workpiece firmly and confirm the pilot hole diameter matches the M3x0.50 thread specification before tapping. Use appropriate cutting fluid for steel to reduce friction and prevent tap breakage.
