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 M12x1.5 tap has a reduced shank to DIN 374: diameter 9 mm, square size 7 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 1.5 mm/rev, equal to the pitch of the M12x1.5 thread.
M12x1.5 INOX machine tap – for CNC machining
In this line, manufacturer Fra offers the M12x1.5 INOX machine tap with optimized cutting geometry for metric fine threads with a pitch of 1.5 mm. The tool meets DIN 374 requirements and provides the 6H thread tolerance class required in series production of mechanical and precision components. Its HSSE steel construction with 5% cobalt guarantees a hardness of 66 HRC and resistance to temperatures up to 650°C in the cutting zone. Form C with straight flutes provides versatility for through and blind holes in stainless steels.
Advantages of the Fra M12x1.5 INOX tap
- Compatibility with ER20 holders collets and synchronized tapping chucks for CNC machining centers with automatic tool change
- Designed for stainless steels austenitic grades 304 and 316, structural steels up to 800 MPa, and nonferrous metals such as aluminum and engineering 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
- M12x1.5 general-purpose machine tap with form C ensures proper chip evacuation in through and blind holes
The M12x1.5 HSSE machine tap is used in steel structures, precision metalworking, and the manufacture of industrial automation components. The Fra M12x1.5 machine tap for through and blind holes is compatible with automatic tool change systems. The tap drill diameter for the M12x1.5 thread is 10.5 mm.

Frequently asked questions
With proper cooling and lubrication, the M12x1.5 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 M12x1.5 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.
