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 M15x1 tap has a reduced shank to DIN 374: diameter 12 mm, square size 9 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 mm/rev, equal to the pitch of the M15x1 thread.
M15x1 INOX machine tap – for stainless steel
The M15x1 INOX machine tap is designed for precision tapping of holes with a diameter of 15 mm and a fine pitch of 1 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 374 confirms high manufacturing quality and dimensional repeatability. The M15x1 HSSE machine tap is intended for maintenance departments and industrial service shops.
Key features of the M15x1 INOX tap
- Manufacturing precision to 6H tolerance guarantees dimensional repeatability and full thread interchangeability in series production of hydraulic and pneumatic components
- Compliance with DIN 374 for fine threads confirms quality and ensures standardized shank dimensions compatible with European 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 ER25 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
- M15x1 general-purpose machine tap with form C allows through and blind holes to be tapped with a single tool without the risk of jamming
The M15x1 machine tap for through and blind holes is suitable for maintenance departments restoring threads and repairing production machinery. It is used in the manufacture of industrial valves and fittings and pneumatic components. The tap drill diameter for the M15x1 thread is 14 mm when cooling with an EP emulsion at a minimum concentration of 8%.

Frequently asked questions
The M15x1 HSSE tap is suitable for austenitic stainless steels 304 and 316, structural steels up to 800 MPa, ductile cast iron, and aluminum and brass alloys. It is not recommended for hardened steels above 45 HRC.
The nominal tap drill diameter for the M15x1 thread is 14 mm. The hole tolerance range should be 13.9–14.1 mm. A hole at the lower tolerance limit produces a fuller thread profile, while one at the upper limit reduces tapping torque.
The M15x1 tap works with ER25 holders and tapping chucks with axial compensation. Synchronized heads with automatic tool change capability are recommended for CNC machines.
