Where chips remain in a straight-flute tap
The flute holds the chips until the tap is reversed out
The straight flute runs parallel to the tap axis. There is no helix to carry chips upward. The chamfer cutting edges are not ground at an angle, so they do not push chips downward. Short chips break into fragments and remain in the flute, next to the cutting edges that produced them. They leave the hole only when the tap is backed out. The M11x1 tap has a reduced shank to DIN 374: diameter 8 mm, square size 6.2 mm.
1
Straight flute – chips remain in the flute, next to the cutting edges that produced them.
2
Chamfer C: 2–3 incomplete threads on the tapered lead.
3
The tap rotates clockwise to cut a right-hand thread.
4
Individual fragments exit at the top, onto the workpiece surface.
5
A few fragments fall below the tip and exit through the bottom of the hole.
6
Feed 1 mm/rev, equal to the pitch of the M11x1 thread.
M11x1 INOX machine tap – for CNC machining
In this range, the manufacturer offers the M11x1 INOX machine tap with optimized cutting geometry for metric fine threads with a pitch of 1 mm. The tool meets DIN 374 requirements and provides the 6H thread tolerance class required for series production of mechanical and precision components. HSSE steel construction with 5% added cobalt ensures a hardness of 66 HRC and resistance to temperatures up to 650°C in the cutting zone. Form C with straight flutes provides versatile use. The M11x1 HSSE machine tap is intended for CNC machining center operators.
Advantages of the M11x1 INOX tap
- Compatibility with ER20 holders collets and synchronized tapping chucks for CNC machining centers with automatic tool change
- 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
- Durability thanks to HSSE steel with 5% cobalt extends cutting edge life by 40-60% compared with standard HSS taps
- M11x1 general-purpose machine tap with form C ensures proper chip evacuation in through and blind holes
The M11x1 machine tap for through and blind holes is used in toolrooms and prototype shops for one-off production of precision components. Cooling with an EP emulsion at a minimum concentration of 8% or with tapping oil extends tool life. The tap drill diameter for the M11x1 thread is 10 mm.

Frequently asked questions
The M11x1 HSSE tap is suitable for austenitic stainless steels 304 and 316, structural steels up to 800 MPa, ductile cast iron, and aluminum and brass alloys. It is not recommended for hardened steels above 45 HRC.
The nominal tap drill diameter for the M11x1 thread is 10 mm. The hole tolerance range should be 9.9–10.1 mm. A hole at the lower tolerance limit produces a fuller thread profile, while one at the upper limit reduces tapping torque.
The M11x1 tap works with ER20 holders and tapping chucks with axial compensation. Synchronized heads with automatic tool change capability are recommended for CNC machines.
