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 M17x1 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 M17x1 thread.
M17x1 INOX machine tap – tool for precision tapping
The M17x1 INOX machine tap is a professional tool for cutting M17 internal threads with a fine pitch of 1 mm in stainless and structural steels. HSSE high-speed steel construction with 5% cobalt provides a hardness of 66 HRC and high resistance to cutting zone temperatures up to 650°C. Form C with straight flutes allows both through and blind holes to be tapped without changing tools. The 6H tolerance in accordance with DIN 374 guarantees dimensional repeatability and full interchangeability with threads cut using other tools of this class. The M17x1 HSSE machine tap is intended for toolrooms and CNC machining center operators.
Key benefits of the M17x1 INOX tap
- Durability and heat resistance thanks to HSSE steel with 5% cobalt, which retains its cutting properties at temperatures up to 650°C in the contact zone with the workpiece material
- Precision to tolerance class 6H according to DIN 374 ensures the dimensional accuracy required in series production of mechanical components and threaded connections
- Compliance with DIN 374 for metric fine threads confirms standardized dimensions and full compatibility with European toolholding systems
- Material versatility covering austenitic stainless steels 304 and 316, structural steels up to 800 MPa, aluminum, and GGG40 ductile cast iron
- Compatibility with ER32 holders and tapping chucks with axial compensation for synchronous tapping on CNC and conventional machines
- Suitable for through holes and blind holes thanks to form C with straight flutes, which ensures proper chip evacuation in both hole types
The M17x1 general-purpose machine tap is used in automotive series production and on assembly lines requiring high repeatability. The M17x1 machine tap for through and blind holes is compatible with ER32 holders and collets. The tap drill diameter for the M17x1 thread is 16 mm.

Frequently asked questions
The M17x1 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 M17x1 thread is 16 mm. The hole tolerance range should be 15.9–16.1 mm. A hole at the lower tolerance limit produces a fuller thread profile, while one at the upper limit reduces tapping torque.
The M17x1 tap works with ER25 holders and tapping chucks with axial compensation. Synchronized heads with automatic tool change capability are recommended for CNC machines.
