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 chamfer for through holes has a chip breaker at the tip of the tap – an angled cut in the cutting edges. The chip breaker directs the chip 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. The threads already cut remain clean because the chip does not pass through them on its way up. The M22x2 tap has a reduced shank according to DIN 374: diameter 18 mm, square size 14.5 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.
6
Feed 2 mm/rev, equal to the pitch of the M22x2 thread.
M22x2 fine thread machine tap – HSSE for machine construction
The M22x2 metric fine thread machine tap from the HSSE series is designed for cutting internal threads with a pitch of 2 mm in machinery structures and components subjected to dynamic loads. High-speed steel construction with 5% cobalt ensures a hardness of 65-67 HRC and long cutting edge life even when machining difficult-to-machine materials. The M22x2 metric fine thread offers better leak tightness and higher strength than the M22x2.5 coarse thread while maintaining fast assembly.
Why choose the M22x2 metric fine thread machine tap
- Fine thread with a 2 mm pitch offers 25% higher tensile strength than the M22x2.5 coarse thread while maintaining quick assembly
- Improved resistance to self-loosening thanks to a finer pitch and a larger helix angle compared with a coarse thread
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and heat resistance up to 650°C, extending tool life when machining alloy steels
- Tolerance 6H according to DIN 374 ensures precise thread production and full interchangeability with standard-grade fasteners
- Material versatility covering structural steels up to 800 MPa, alloy steels, gray and ductile cast iron, and aluminum
- Recommended tap drill diameter 20 mm for the M22x2 metric fine thread ensures optimal thread engagement
The M22x2 fine thread machine tap is used in machine building, steel structures, and the automotive industry where higher strength than a coarse thread provides is required. Form B with straight flutes directs chips forward when tapping through holes. Cooling with an oil emulsion at a concentration of 6-8% is recommended.
