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 M15x1.5 tap has a reduced shank according to DIN 374: diameter 12 mm, square size 9 mm.
M15x1.5 fine-thread machine tap – HSSE for industrial applications
The M15x1.5 metric fine thread machine tap is a specialized tool for cutting internal threads with a nonstandard diameter of 15 mm and a pitch of 1.5 mm for industrial applications. Its HSSE high-speed steel construction with 5% added cobalt ensures a hardness of 65-67 HRC and optimum tool life when machining difficult-to-machine materials requiring high precision. The 1.5 mm pitch is a standard fine pitch for diameters in the M14-M16 range, offering a good balance between strength and assembly speed. The tool is designed for professional toolrooms and prototype shops fulfilling industrial orders.
Key features of the M15x1.5 metric fine thread machine tap
- Nonstandard M15 size fills the gap between the popular M14 and M16 sizes, used in special designs with specific dimensional or strength requirements
- Fine thread with a 1.5 mm pitch is the standard fine pitch for this diameter group, providing good strength and sealing of the threaded connection
- 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
- The 6H tolerance in accordance with DIN 374 ensures thread accuracy and full interchangeability with fasteners used in industry and prototype shops
- Material versatility covering structural steels up to 800 MPa, alloy steels, austenitic stainless steels 304/316, and gray and ductile cast iron
- The recommended tap drill diameter of 13.5 mm for the M15x1.5 metric fine thread ensures optimal thread engagement with minimal tool load
The M15x1.5 machine tap is used in industrial hydraulics, prototype shops, and special applications requiring a nonstandard M15 diameter with a fine pitch. 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 to maintain optimum tool life.
