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 M19x1 tap has a reduced shank to DIN 374: diameter 13 mm, square size 10.8 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 mm/rev, equal to the pitch of the M19x1 thread.
M19x1 INOX machine tap – compliant with DIN 374
The M19x1 INOX machine tap is designed for precision tapping of holes with a diameter of 19 mm and a fine pitch of 1 mm in stainless and structural steels. Made from HSSE high-speed steel with 5% cobalt, it guarantees a hardness of 66 HRC and long cutting edge life even when machining difficult-to-machine materials. Form C with straight flutes provides versatility for through and blind holes. The 6H tolerance in accordance with DIN 374 confirms high manufacturing quality and dimensional repeatability. The M19x1 HSSE machine tap is intended for series production departments and industrial service shops.
Key features of the M19x1 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 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
- Material versatility covering austenitic stainless steels 304 and 316, structural steels up to 800 MPa, gray and ductile cast iron, and aluminum alloys
- Compatibility with ER32 holders and tapping heads for CNC machining centers with synchronous tapping and automatic tool changing
- M19x1 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 M19x1 machine tap for through and blind holes is used in steel structures and industrial welding applications requiring durable threaded connections. It is suitable for manufacturing automation components and fittings. The tap drill diameter for the M19x1 thread is 18 mm.

Frequently asked questions
The M19x1 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 M19x1 thread is 18 mm. The hole tolerance range should be 17.9–18.1 mm. A hole at the lower tolerance limit produces a fuller thread profile, while one at the upper limit reduces tapping torque.
The M19x1 tap works with ER25 holders and tapping chucks with axial compensation. Synchronized heads with automatic tool change capability are recommended for CNC machines.
