RUKO MGB Set HSSCo VAP 35° M3-M12 sada strojných závitníkov

Threading a range of metric holes in tough materials can require multiple taps and frequent tool changes. This 7-piece machine tap set covers M3 to M12 coarse threads in one organized case, with a 35° spiral flute that pulls chips backward for efficient blind-hole work.

Who is it for

Machinists and maintenance technicians who tap unalloyed and alloyed steels, stainless steels, cast iron, and non-ferrous metals up to 1000 N/mm² tensile strength. Suitable for both through and blind holes.

Main features

• High-speed steel cobalt (HSSCo) with vaporized surface treatment for wear resistance.
• 35° right-hand spiral flute design for effective chip evacuation.
