Product Description
The Bohrcraft DIN 371 HSS-G machine tap M 3 x 0,5 Form B is an industrial-grade single-pass tap designed for production through-hole tapping on drill presses and machining centers. The Form B spiral point lead chamfer (4–5 threads) shears chips cleanly and shoots them forward ahead of the tool, preventing flute congestion and surface scoring in through-holes up to 3xD depth. Manufactured from fully-ground high-speed steel for steels up to 800 N/mm² (ISO2 / 6H tolerance).
