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 M33x2 tap has a reduced shank to DIN 374: diameter 25 mm, square size 20 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 2 mm/rev, equal to the pitch of the M33x2 thread.
M33x2 INOX machine tap – for through and blind holes
This HSSE series model, designed for cutting M33x2 metric fine threads in stainless and structural steels, features a pitch of 2 mm. The M33x2 INOX machine tap provides an optimum balance between connection tightness and ease of assembly. 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 M33x2 machine tap for through holes and blind holes is intended for manufacturers of hydraulic and pneumatic components.
Key advantages of the M33x2 general-purpose HSSE tap
- Pitch 2 mm provides an optimum balance between connection load capacity and assembly speed in industrial applications requiring frequent disassembly
- Material versatility covering 304 and 316 austenitic stainless steels, structural steels up to 800 MPa, GGG40 ductile cast iron, and aluminum alloys
- Compatibility with ER40 holders and collets for precise clamping on machining centers with axial compensation and automatic tool changing
- Precision to tolerance class 6H for demanding fit tolerances in series production of high-precision mechanical and hydraulic components
- Compliance with DIN 374 for fine threads ensures standardized shank dimensions and interchangeability with tools from European manufacturers
- M33x2 HSSE machine tap with form C allows tapping of through holes and blind holes without changing the tool or parameters
The M33x2 general-purpose machine tap is used in series production of hydraulic power components and industrial valves and fittings. Cooling with an EP emulsion at a minimum concentration of 8% extends tool life. The tap drill diameter for the M33x2 thread is 31 mm.

Frequently asked questions
With proper cooling and lubrication, the M33x2 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 M33x2 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.
