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 M36x2 tap has a reduced shank to DIN 374: diameter 28 mm, square drive 22 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 2 mm/rev, equal to the pitch of the M36x2 thread.
M36x2 INOX machine tap – HSSE with a 40° helical cutting edge
In this range, the manufacturer offers an M36x2 INOX R40 machine tap with special 40° helical cutting edge geometry optimized for tapping blind holes. The tool meets DIN 374 requirements and provides the 6H thread tolerance class required in series production of mechanical and precision components. HSSE steel construction with 5% cobalt ensures a hardness of 66 HRC and resistance to temperatures up to 650°C in the cutting zone. The 40° flute helix angle directs chips forward, keeping the bottom of the hole clean.
Benefits of the M36x2 R40 universal tap
- 40° helical cutting edge directs chips forward and out of the hole, making it ideal for tapping through holes and ensuring a clean thread
- Durability increased by the addition of cobalt in HSSE steel extends cutting edge life by 40-60% compared with standard HSS taps
- Material versatility covering austenitic stainless steels 304 and 316, structural steels up to 800 MPa and nonferrous metals such as aluminum and brass
- Precision to tolerance class 6H meeting the requirements of series production of mechanical and pneumatic components with tight fit tolerances
- Conforms to DIN 374 for fine threads ensures standardized shank dimensions and interchangeability with tools from European manufacturers
- M36x2 R40 HSSE machine tap with helical geometry ensures effective chip evacuation at high cutting speeds on CNC machining centers
The general-purpose M36x2 R40 machine tap is used in series production on CNC machining centers requiring efficient chip evacuation. The M36x2 machine tap for through and blind holes is compatible with ER40 collet chucks. The tap drill diameter for the M36x2 thread is 34 mm.

Frequently asked questions
The M36x2 R40 HSSE tap with a 40° helical cutting edge is suitable for 304 and 316 austenitic stainless steels, structural steels up to 800 MPa, and ductile cast iron. The R40 geometry ensures efficient forward chip evacuation.
The R40 tap has a right-hand helical cutting edge at a 40° angle that directs chips forward, toward the through hole. This design is optimal for blind holes and prevents chip accumulation in the cutting zone.
The M36x2 R40 tap works with ER40 collet chucks and tapping chucks with axial compensation. Synchronized tapping heads with automatic tool change capability are recommended for CNC machines.
