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 M11x0.75 tap has a reduced shank according to DIN 374: diameter 8 mm, square size 6.2 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 0.75 mm/rev, equal to the pitch of the M11x0.75 thread.
M11x0.75 fine-thread machine tap – HSSE for precision engineering
The M11x0.75 fine-thread machine tap made of HSSE steel is designed for precision tapping at a nonstandard diameter of 11 mm in precision engineering. High-speed steel with 5% cobalt ensures a hardness of 65-67 HRC and optimum tool life when machining difficult-to-machine materials requiring extreme precision. The M11x0.75 metric fine thread combines a nonstandard diameter with a reduced pitch, providing extreme adjustment precision and resistance to self-loosening. The tool is intended for professional toolrooms handling custom orders in optics and precision engineering.
Technical specifications of the M11x0.75 metric fine thread machine tap
- Nonstandard M11 size fills the gap between the popular M10 and M12 sizes in structures with specific dimensional or strength requirements in the mechanical design
- Fine thread with a 0.75 mm pitch provides extreme positioning precision — one full revolution produces a displacement of just 0.75 mm with high resistance to self-loosening
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and thermal resistance up to 650°C required when machining alloy steels and difficult-to-machine materials
- Tolerance class 6H according to DIN 374 ensures precise thread production and full interchangeability with fasteners used in precision mechanics and optics
- Compatibility with ER16 and ER20 holders and tapping chucks with axial compensation for CNC machining centers with synchronous tapping capability
- The recommended tap drill diameter of 10.2 mm for the M11x0.75 metric fine thread ensures optimal thread engagement with minimal tool load
The M11x0.75 machine tap is used in industrial optics, precision engineering, measuring instruments, and wherever a combination of a nonstandard diameter and extreme adjustment precision is required. Form B with straight flutes directs chips forward. Cooling with an oil emulsion at a concentration of 6-8% is recommended to maintain optimum tool life.
