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 M35x1.5 tap has a reduced shank according to DIN 374: diameter 28 mm, square size 22 mm.
M35x1.5 metric fine thread machine tap – HSSE for specialized hydraulics
The HSSE tap series designed for professional toolrooms includes an M35x1.5 metric fine thread machine tap in cobalt steel. Tolerance 6H according to DIN 374 guarantees the dimensional repeatability needed for manufacturing hydraulic components with a nonstandard diameter of 35 mm. Made of high-speed steel with 5% cobalt, the tool achieves a hardness of 65-67 HRC and heat resistance up to 650°C. The M35 thread is used in specialized applications where standard M33 or M36 threads do not meet requirements.
Why choose the M35x1.5 metric fine thread machine tap
- Nonstandard M35 size used in specialized hydraulic applications requiring an intermediate diameter between M33 and M36
- Fine thread with a 1.5 mm pitch is standard in industrial hydraulics, providing excellent leak tightness at high pressures
- 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 according to DIN 374 ensures precise thread production and full interchangeability with fasteners
- Compatibility with ER40 holders and collets for precise clamping on CNC machining centers
- Recommended tap drill diameter 33.5 mm for the M35x1.5 metric fine thread ensures optimal thread engagement
The M35x1.5 machine tap is used in specialized hydraulic applications, manufacturing of nonstandard valve blocks and prototyping of heavy-duty hydraulic components. The metric fine thread provides good joint leak tightness. Cooling with an emulsion containing EP additives at a concentration of 8-10% is recommended.
