Fully ground HSS-Co5 M35 spiral-flute machine tap for cutting metric internal threads in stainless steel and other compatible metals. The upward chip-evacuation design is suitable for blind and deep holes, with nine coarse-thread sizes available from M3 × 0.5 to M16 × 2.0.
Key Features
- HSS-Co5 M35 high-speed steel with approximately 5% cobalt for improved hardness and heat resistance
- Spiral flutes direct chips upward for efficient blind-hole and deep-hole threading
- Fully ground cutting edges produce accurate dimensions and clean internal threads
- Metric coarse thread geometry with ISO 2 accuracy for machine-tapping applications
- Round shank with square drive for secure mounting in compatible machine-tool holders

Applications
Suitable for compatible stainless steel, carbon steel, mould steel, cast iron, aluminium alloys and copper. Designed for use with tapping machines, automatic machine tools, machining centres, CNC machines and suitable drilling machines.
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 an operating speed approximately 30% lower than comparable straight-flute taps.
