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 M42x2 tap has a reduced shank according to DIN 374: diameter 32 mm, square size 24 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 M42x2 thread.
M42x2 fine thread machine tap – HSSE for machine construction
The HSSE tap series designed for professional toolrooms includes the M42x2 metric fine thread machine tap in cobalt steel. The 6H tolerance in accordance with DIN 374 guarantees the dimensional repeatability essential for producing structural components with a large diameter of 42 mm. Made from high-speed steel with 5% added cobalt, the tool achieves a hardness of 65-67 HRC and thermal resistance up to 650°C. The M42x2 metric fine thread offers higher strength than the M42x4.5 coarse thread.
Why choose the M42x2 metric fine thread machine tap
- Fine thread with a 2 mm pitch offers more than twice the tensile strength of the M42x4.5 coarse thread while maintaining relatively 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 cutting edge life
- Tolerance 6H in accordance with DIN 374 ensures thread accuracy and full interchangeability with standard-grade fasteners
- Compatibility with ER40 holders and collets for precise clamping on CNC machining centers
- The recommended hole diameter of 40 mm for the M42x2 metric fine thread ensures an optimal percentage of thread engagement
The M42x2 machine tap is used in heavy machinery manufacturing, steel structures and the power industry, where greater strength than a coarse thread provides is required. Form B with straight flutes directs chips forward. Cooling with an oil emulsion at a concentration of 8-10% is recommended.
