Description

Version:

High-performance tap, specially developed for use in steels with high tensile strength and for difficult-to-machine materials. Sturdy design with optimised guide thread to avoid chips jamming.
  • HSS-E-PM tool material – for very high cutting edge stability.
  • Optimised honed cutting edges.
  • TiAlN coating – for maximum wear protection.

Tolerance class: ISO 3X/6GX.

Application:

For components which are galvanised or shrink slightly when hardened.

Recommendation:

For TOOLOX and HARDOX materials we recommend deviating from the DIN data (see table) by selecting a larger tapping hole .

Note:

For TOOLOX and HARDOX materials: do not exceed the maximum thread depth 2×D!
