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 M6x0.75 tap has a reduced shank to DIN 374: diameter 6 mm, square size 4.9 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 0.75 mm/rev, equal to the pitch of the M6x0.75 thread.
M6x0.75 INOX machine tap – HSSE tool for stainless steel
The Fra M6x0.75 INOX machine tap is a professional tool for cutting internal M6 threads with a fine pitch of 0.75 mm in stainless and structural steels. Its 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. The general-purpose M6x0.75 machine tap is intended for toolrooms and CNC machining center operators.
Key advantages of the M6x0.75 tap for through holes and blind holes
- Fine pitch of 0.75 mm provides more threads per unit length, increasing the sealing performance and load capacity of the joint in precision components
- Durability and heat resistance thanks to HSSE steel with 5% cobalt, which maintains its cutting properties at temperatures up to 650°C in the contact zone
- Precision to tolerance class 6H ensures the dimensional accuracy required in the production of electronic and precision mechanical components
- Compatibility with ER16 holders and tapping chucks with axial compensation for synchronous tapping on CNC and conventional machines
- Designed for stainless steels austenitic 304 and 316 and difficult-to-machine materials requiring tools with enhanced resistance
- M6x0.75 HSSE machine tap with form C evacuates chips properly in through holes and blind holes without the risk of thread damage
The Fra M6x0.75 machine tap for through and blind holes is used in precision electronics and the production of optical components. European manufacturing quality ensures reliability. The tap drill diameter for the M6x0.75 thread is 5.25 mm.

Frequently asked questions
With proper cooling and lubrication, the M6x0.75 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 M6x0.75 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.
