GBP 57 MF B 60° HSS-E- DIN DIN ISO 2X h9 PM 374 13 6HX 4 ≤3×D GARANT Master Tap SteelHT through hole machine tap High-performance tap, specially developed for use in steels with high tensile strength and for difficult-to-machine materials. Strong spiral point, for process stability at high cutting forces. ■ HSS-E-PM tool material – for very high cutting edge stability. ■ Optimised honed cutting edges. 13 2855 ■ TiCN coating – for maximum wear protection. Recommendation: For TOOLOX and HARDOX materials we recommend deviating from the DIN data (see table) by selecting a larger tapping hole ⌀.

Example for thread forming: Due to the low cutting speed, a lower cooling effect but a very high lubricating effect are required. It is also imperative to pay attention to the type of cooling lubricant. To determine the intended cooling lubricant and the process, the respective specification in the application table under the products is used: Example and explanation* Suitable only under restricted Oil lubrication Minimum quantity lubrication Compressed air supply ○ conditions Emulsion (for taps Dry machining ● Suitable Unsuitable with at least 8% grease) *In addition, the recommendations in the product description must be observed. 284
