Outstanding performance and cost-effectiveness
- Up to 12x longer service life and up to 150 % faster cutting speed compared to conventional uncoated machine taps
- Up to 9x longer service life and up to 50 % faster cutting speed compared to conventional machine taps with TiN coating
- Excellent chip removal, prevents chip accumulation
Magma multi-layer coating
- Multi-layer design ensures reduced friction values, low adhesion tendency and optimal chip removal
- Extremely high temperature resistance up to 800 °C
- Very high coating hardness of 3,000 HV
Optimal adhesion of the coating and reduced risk of chipping on the tool
The extra homogeneous cutting edge rounding ensures high process reliability and even longer service life compared to conventional machine taps.
Can be used reliably in almost all materials
Newly developed tool geometry with reduced rake angle as well as optimised clearance angle and microgeometry
X allowance for longer service life and increased process reliability
Ideal for demanding machining and series production with a high number of threads
Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze
- When thread cutting, sufficient coolant and lubricant must be added
- For the machine tap/material assignments, see the overview tables
Datasheets(X)
Before reversing the screw tap, the entire spiral point of the tool must be removed from the drill hole. Failure to do so may cause cutting edges to chip or the tool to break.
