How a spiral flute tap evacuates chips from a blind hole
The 40° flute works like a screw conveyor
The flutes of this tap follow a right-hand helix at an angle of 40° 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 M10x1 tap has a reduced shank to DIN 374: diameter 7 mm, square drive 5.5 mm.
1
The 40° 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 1 mm/rev, equal to the pitch of the M10x1 thread.
M10x1 spiral-flute machine tap – metric fine thread for precision joints
The fine-thread tap series designed for industrial hydraulics includes the M10x1 spiral flute machine tap with a pitch of 1 mm. The 6H tolerance in accordance with DIN 374 guarantees leak-tight threaded joints in pressure systems up to 400 bar. HSSE steel construction with 5% cobalt provides a hardness of 65-67 HRC and heat resistance up to 650°C. The 40° spiral flute directs chips backward when tapping blind holes in valve blocks and hydraulic housings.
Why choose the M10x1 spiral flute machine tap
- Compliance with DIN 374 for metric fine threads ensures standardized dimensions and full interchangeability with tools from European manufacturers
- Designed for industrial hydraulics includes valve blocks, cylinder bodies, directional control valves, and pressure system components rated up to 400 bar
- Tolerance class 6H precision guarantees leak-tight threaded connections without the need for additional seals in hydraulic applications
- Durability of HSSE steel with 5% cobalt allows operation at temperatures up to 650°C without loss of the cutting edge's mechanical properties
- Form C chamfer for blind holes allows tapping close to the bottom of the hole with a minimal incomplete thread length of 2-3 pitches
- 40° spiral flutes provide aggressive chip evacuation when tapping deep blind holes in hydraulic housings
The M10x1 spiral flute tap is used in the production of valve blocks and industrial fittings requiring leak-tight joints. The fine pitch of 1 mm provides a larger contact area than the standard M10x1.5 thread. The tap drill diameter for the M10x1 thread is 9.0 mm according to fine-thread tables.

Frequently asked questions
The M10x1 HSSE fine thread machine tap is suitable for structural steels up to 900 MPa, austenitic stainless steels 304/316, aluminum, and brass. The fine pitch of 1 mm provides improved joint sealing in hydraulic applications.
For the M10x1 metric fine thread in tolerance class 6H, the recommended tap drill diameter is 9.0 mm. The hole tolerance zone should fall within the range of 9.0 to 9.2 mm. Exceeding the upper limit results in an incomplete thread profile.
Yes, cooling with an oil emulsion of at least 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, while aluminum can be tapped with minimum quantity lubrication (MQL).
