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 M36x3 tap has a reduced shank according to DIN 374: diameter 28 mm, square size 22 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 3 mm/rev, equal to the pitch of the M36x3 thread.
M36x3 fine-thread machine tap – HSSE for industrial applications
The M36x3 fine-thread machine tap is designed for precision tapping of large-diameter 36 mm holes in industrial components. Its HSSE high-speed steel construction with 5% cobalt guarantees a hardness of 65-67 HRC and optimum tool life when machining materials with a strength of up to 800 MPa. The 3 mm pitch falls between the M36x4 coarse thread and typical fine threads, offering a balance between assembly speed and threaded joint strength.
Technical specifications of the M36x3 metric fine thread machine tap
- Fine thread with a 3 mm pitch offers a balance between the assembly speed of a coarse thread and the strength of a fine thread
- Increased load-bearing area of the thread of the fine thread results in more uniform load distribution and greater strength than a coarse thread
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and heat resistance up to 650°C, essential for machining alloy steels
- The 6H tolerance in accordance with DIN 374 ensures thread accuracy and full interchangeability with fasteners
- Compatibility with ER40 holders and collets for precise clamping on CNC machining centers
- The recommended hole diameter of 33 mm for the M36x3 metric fine thread ensures an optimal percentage of thread engagement
The M36x3 machine tap is used in heavy machinery construction, steel structures, and the energy industry where greater strength than a coarse thread provides is required while maintaining relatively fast assembly. Form B with straight flutes directs chips forward. Cooling with an oil emulsion at a concentration of 8-10% is recommended.

Frequently asked questions
The M36x3 fine thread provides approximately 30-40% higher tensile strength than the M36x4 coarse thread while maintaining relatively fast assembly and good fastener availability.
The recommended tap drill diameter for the M36x3 metric fine thread is 33 mm. Precise hole machining ensures full thread engagement.
The M36x3 thread is used in heavy machinery construction, steel structures, and the energy industry where greater strength than a coarse thread provides is required.
