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 M23x1.25 tap has a reduced shank to DIN 374: diameter 18 mm, square size 14 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 1.25 mm/rev, equal to the pitch of the M23x1.25 thread.
M23x1.25 INOX machine tap – tool for precision tapping
This HSSE series model, designed for cutting M23x1.25 fine threads in stainless and structural steels, features a nonstandard diameter of 23 mm. The M23x1.25 INOX machine tap provides more threads per unit length, ensuring higher joint load capacity and better sealing performance. With 5% cobalt, the tool maintains a hardness of 66 HRC even at cutting zone temperatures up to 650°C. Form C with straight flutes provides versatile use. The M23x1.25 HSSE machine tap is intended for manufacturers of hydraulic and special-purpose components.
Key benefits of the M23x1.25 INOX tap
- Compatibility with ER32 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
- Durability increased by the addition of cobalt in HSSE steel allows 400-600 threads to be cut in structural steel with proper emulsion cooling
- Precision to tolerance class 6H for demanding fit tolerances in series production of mechanical, hydraulic and pneumatic components
- Compliance with DIN 374 for fine threads ensures standardized shank dimensions and interchangeability with tools from European manufacturers
- M23x1.25 general-purpose machine tap with form C allows tapping of through holes and blind holes without changing the tool or parameters
The M23x1.25 machine tap for through and blind holes is used in series production of special-purpose components and on assembly lines requiring nonstandard threads. It performs well in components requiring leak-tight joints with high load capacity. The tap drill diameter for the M23x1.25 thread is 21.75 mm.

Frequently asked questions
With proper cooling and lubrication, the M23x1.25 HSSE tap cuts 400-600 threads in structural steel or 250-350 threads in stainless steel. Dry operation reduces tool life by 40-50%.
Yes, the M23x1.25 HSSE tap with 5% cobalt is designed for austenitic stainless steels 304 and 316. The addition of cobalt increases heat resistance in the cutting zone to 650°C.
An HSSE tap contains 5% cobalt, which increases hardness from 64 to 66 HRC and heat resistance to 650°C. HSSE is suitable for stainless steels, while HSS is suitable only for structural steels up to 800 MPa.
