How the type B through-hole chamfer pushes chips down the hole
Chips exit at the bottom instead of returning through the thread
The form B through-hole chamfer has a chip breaker at the front of the tap – an angled cut in the cutting edges. The chip breaker directs chips down the hole, ahead of the tap tip. The chip curls into a coil, breaks into short pieces, and exits the hole on the other side of the workpiece. Threads already cut remain clean because chips do not pass through them on their way up. The M6 x1 tap has a reinforced shank in accordance with DIN 371: diameter 6 mm, square 4.9 mm.
1
Straight flute – chips do not enter it; the flute carries lubricant to the cutting edges.
2
The chip breaker at the tip of the tap directs chips down the hole.
3
The tap rotates clockwise to cut a right-hand thread.
4
B chamfer: 3.5–5.5 incomplete threads on the entry taper.
5
The chips break into segments: individual pieces at the top of the hole, with progressively more farther down. They fall out below the workpiece.

Feed 1 mm/rev, equal to the pitch of the M6 x1 thread.
M6 machine tap for through holes – HSSE-PM powder metallurgy steel
The M6 machine tap for through holes, made from HSSE-PM powder metallurgy steel, is a professional tool for the most demanding applications in high-volume production. Powder metallurgy (PM) technology provides a uniform microstructure and a hardness of 67-69 HRC, significantly exceeding the properties of conventional HSSE taps. M6 is among the most popular metric thread sizes, and the powder metallurgy steel construction ensures 2-3 times the tool life of standard tools.
Key benefits of the M6 HSSE-PM machine tap
- HSSE-PM powder metallurgy steel with a uniform microstructure ensures a hardness of 67-69 HRC and 2-3 times the service life of conventional HSSE taps
- Most popular M6 size used across all industries — from electronics and automotive to machine building
- Increased wear resistance thanks to the uniform carbide structure, which translates into consistent performance throughout the service life
- The 6H tolerance in accordance with DIN 371 ensures thread accuracy and full interchangeability with fasteners
- Optimal geometry for difficult-to-machine materials, austenitic stainless steels, and titanium alloys
- Short shank according to DIN 371, compatible with ER16 and ER20 holders and tapping chucks with axial compensation
The M6 HSSE-PM machine tap is used in high-volume automotive, aerospace and medical manufacturing, where maximum productivity and repeatability with minimal downtime are required. Powder metallurgy steel is particularly effective when tapping stainless steels. Cooling with an emulsion containing EP additives at a concentration of 8-10% is recommended.
