• Global compatibility with metric screws/nuts

DIN 371 (reinforced shank)

• More stability & break-resistance
• Used for smaller sizes up to M10
• In this set: M3–M10 to DIN 371

DIN 376 (reduced shank)

• Improved chip evacuation on larger sizes
• In this set: M12 to DIN 376

ISO 2 / 6H — Tolerance

• Common fit for internal threads (easy running to close fit)
• Compatible with external threads such as 6g / 6h

HSS-E — Material

• Cobalt-alloyed high-speed steel
• High hot hardness and wear resistance for long tool life
• Great for tougher, long-chipping or stainless materials

Are the taps suitable for blind holes?
Form B spiral-point taps push chips forward and are primarily intended for through holes. For blind holes, choose the appropriate lead geometry.

Do I get the drills I need for core holes?
Yes, the matching HSS twist drills for M3–M12 are included.

Can I order single items later?
Yes, all taps and accessories are available individually under the listed article numbers.

Which shank standards apply?
M3–M10 to DIN 371 (reinforced shank), M12 to DIN 376 (reduced shank).

Is HSS-E necessary?
HSS-E provides hot-hardness and wear resistance for reliable performance, especially in tougher materials.
