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 M22x2 tap has a reduced shank to DIN 374: diameter 18 mm, square size 14.5 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 2 mm/rev, equal to the pitch of the M22x2 thread.
M22x2 INOX machine tap – compliant with DIN 374
The Fra M22x2 INOX machine tap is designed for precision tapping of holes with a diameter of 22 mm and a fine pitch of 2 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 M22x2 HSSE machine tap is intended for series production departments and industrial service shops.
Key features of the Fra M22x2 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
- M22x2 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 Fra M22x2 machine tap for through and blind holes is used in steel structures and industrial welding applications requiring durable threaded joints. European manufacturing quality ensures long service life. The tap drill diameter for the M22x2 thread is 20 mm.

Frequently asked questions
The M22x2 HSSE tap with form C and straight flutes is versatile – it is suitable for both through and blind holes. The design ensures proper chip evacuation in both types of holes.
The M22x2 HSSE tap cuts internal threads to tolerance class 6H. The 6H designation defines the permissible deviations of the thread pitch and minor diameters – the digit 6 indicates the width of the tolerance zone (medium), while the letter H indicates the position of the zone at the zero line. The 6H tolerance ensures a proper fit with screws of tolerance class 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.
