Fully ground HSS M2 (6542) spiral-flute machine tap for cutting metric internal threads in steel and other compatible metals. Available in 11 coarse-thread sizes from M3 × 0.5 to M20 × 2.5, each with a square-drive shank for secure machine mounting.
Key Features
- HSS M2 (6542) construction combines wear resistance, hardness and working toughness
- Spiral flutes direct chips away from the cutting area for efficient blind-hole threading
- Fully ground cutting edges produce accurate dimensions and clean internal threads
- Metric ISO 2 accuracy with H2 marking for general machine-tapping applications
- Round shank with square drive for secure mounting in compatible machine-tool holders

Applications
Suitable for tapping compatible carbon steel, structural steel, tool steel, mould steel, bearing steel, cast iron, aluminium alloys and copper materials up to approximately HB300. Compatible with suitable machining centres, tapping machines, radial drilling machines and bench drills.
Operating Guidance
Use suitable cutting fluid or tapping oil and select the speed according to the tap size and workpiece material. Spiral-flute taps generally require a lower operating speed than comparable straight-flute taps.
