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 M27x2 tap has a reduced shank to DIN 374: diameter 20 mm, square size 16 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 M27x2 thread.
M27x2 INOX machine tap – general-purpose tool for CNC machining
In this range, the manufacturer offers the M27x2 INOX machine tap with optimized cutting geometry for metric fine threads with a pitch of 2 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 in through and blind holes in stainless steels.
Advantages of the M27x2 HSSE tap for through holes and blind holes
- Compatibility with ER32 holders collets and synchronized tapping chucks for CNC machining centers with automatic tool change
- 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
- M27x2 general-purpose machine tap with form C ensures proper chip evacuation in through holes and blind holes without the risk of jamming
The M27x2 HSSE machine tap is used in steel structures, industrial welding, and the production of industrial automation components. The M27x2 machine tap for through and blind holes is compatible with automatic tool change systems. The tap drill diameter for the M27x2 thread is 25 mm.

Frequently asked questions
With proper cooling and lubrication, the M27x2 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 M27x2 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.
