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. It has 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, beside the cutting edges that produced them. They leave the hole only when the tap is backed out. The M10 x1.5 tap has a reinforced shank according to DIN 371: diameter 10 mm, square drive 8 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.

Feed 1.5 mm/rev, equal to the pitch of the M10 x1.5 thread.
M10 INOX machine tap – for stainless and alloy steel
The M10 INOX machine tap is designed for precision tapping of holes with a diameter of 10 mm in stainless and structural steels. HSSE high-speed steel construction with 5% cobalt ensures a hardness of 66 HRC and long cutting edge life even when machining difficult-to-machine materials. Form C with straight flutes provides versatile use in through and blind holes. The 6H tolerance according to DIN 371 confirms high manufacturing quality and dimensional repeatability. The M10 HSSE machine tap is intended for maintenance departments and industrial service shops.
Key features of the M10 INOX tap
- Manufacturing precision to 6H tolerance ensures dimensional repeatability and full thread interchangeability in series production of mechanical and hydraulic components
- Compliance with DIN 371 confirms quality and ensures standardized short shank dimensions compatible with European and Asian tool holders
- Durability increased by the addition of 5% cobalt allows operation at temperatures up to 650°C without loss of cutting edge performance
- Compatibility with ER16 holders and tapping heads for CNC machining centers with synchronous tapping and automatic tool changing
- Designed for stainless steels austenitic grades 304 and 316 and ferritic grades, which require tools with increased heat and abrasion resistance
- Universal M10 machine tap with form C and straight flutes allows through and blind holes to be tapped with a single tool
The M10 machine tap for through and blind holes is suitable for maintenance departments restoring threads and repairing production machinery in industrial plants. It is also used in service and repair shops. The tap drill diameter for the M10 thread is 8.5 mm, with cooling provided by an EP emulsion at a minimum concentration of 8%.

Frequently asked questions
The M10 HSSE tap with form C and straight flutes is universal – suitable for both through holes and blind holes. Its design ensures proper chip evacuation in both hole types.
The M10 HSSE tap produces an internal thread to tolerance class 6H. The designation 6H specifies the permissible deviations of the thread pitch and minor diameters – the digit 6 indicates the tolerance zone width (medium), and the letter H indicates the position of the zone at the zero line. Tolerance 6H ensures proper fit with screws to tolerance 6g.
When tapping stainless steels, an EP emulsion at a minimum concentration of 8% or tapping oil is recommended for cooling. Cooling extends tool life by a factor of 2-3 and improves the thread surface finish.
