How a spiral flute tap evacuates chips from a blind hole
The 35° flute works like a screw conveyor
The flutes of this tap follow a right-hand helix at an angle of 35° to the axis. The tap rotates clockwise and advances into the hole. Chips cut by the chamfer enter the flute, and the helix carries them upward like the auger in a meat grinder. The bottom of the hole stays clear, and the cutting edges do not encounter packed chips. The M6x0.75 tap has a reduced shank to DIN 374: diameter 6 mm, square drive 4.9 mm.
1
The 35° spiral flute carries chips upward from the chamfer.
2
The stepped chip exits the hole and breaks into short pieces.
3
The tap rotates clockwise to cut a right-hand thread.
4
Chamfer C: 2–3 incomplete threads on the tapered lead.
5
Clearance below the tap tip – min. 2 thread pitches above the bottom.
6
Feed 0.75 mm/rev, equal to the pitch of the M6x0.75 thread.
M6x0.75 spiral-flute machine tap – metric fine thread for precision joints
The M6x0.75 spiral flute machine tap from the metric fine thread series is designed for cutting reduced-pitch threads in precision engineering. HSSE steel with 5% added cobalt provides a hardness of 65-67 HRC and high cutting-edge heat resistance up to 650°C. The 35° spiral flute ensures controlled chip evacuation when tapping deep blind holes. The form C chamfer makes the tool particularly suitable for blind-hole tapping close to the bottom of the hole. Tolerance 6H in accordance with DIN 374 meets precision manufacturing requirements.
Key features of the M6x0.75 spiral flute machine tap
- Manufacturing precision to 6H tolerance guarantees dimensional repeatability and full thread interchangeability in series production of mechanical components
- Compliance with DIN 374 confirms quality and ensures standardized dimensions for metric fine threads compatible with European standards
- Durability of HSSE steel with 5% cobalt allows operation at temperatures up to 650°C without loss of the cutting edge's mechanical properties
- Compatibility with ER16 and ER20 tool holders and tapping heads for CNC machining centers with synchronous tapping capability
- Designed for precision engineering includes electronic enclosures, optical components, measuring equipment, and medical instruments
- 35° spiral flutes ensure consistent chip evacuation when tapping blind holes up to 2.5D deep without the risk of breakage
The M6x0.75 spiral flute tap is suitable for manufacturing electronic components and precision mechanisms requiring leak-tight threaded connections. The fine pitch of 0.75 mm provides a larger contact area than the standard M6x1 thread. The tap drill diameter for the M6x0.75 thread is 5.25 mm in accordance with metric fine thread tables.

Frequently asked questions
The M6x0.75 HSSE machine tap for metric fine threads is suitable for structural steels up to 900 MPa, stainless steels, aluminum, and brass. The fine pitch of 0.75 mm provides improved sealing in precision connections.
For the M6x0.75 metric fine thread in tolerance class 6H, the tap drill diameter should be 5.25 mm. The permissible hole tolerance range is 5.25-5.4 mm. A smaller hole increases cutting torque and the risk of tool breakage.
Yes, cooling with an oil emulsion at a minimum concentration of 8% or with tapping oil is recommended and extends tool life by a factor of 2-3. Intensive cooling is required when machining stainless steels.
