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 M32x2 tap has a reduced shank to DIN 374: diameter 22 mm, square size 18 mm.

M32x2 INOX machine tap – general-purpose HSSE tool for CNC machining

The HSSE series, designed for manufacturing engineers and CNC operators working with large diameters, includes the M32x2 INOX machine tap for metric fine threads. The 6H tolerance in accordance with DIN 374 guarantees the dimensional repeatability required in the production of hydraulic and pneumatic components with stringent sealing requirements. The thread pitch of 2 mm provides an optimum balance between connection load capacity and ease of assembly. Its HSSE steel construction with 5% cobalt guarantees a hardness of 66 HRC and long cutting edge life in stainless and difficult-to-machine steels.

Key features of the M32x2 tap for through and blind holes

  • Compliance with DIN 374 for metric fine threads ensures standardized dimensions and full interchangeability with tools from European tool manufacturers
  • Designed for stainless steels of austenitic grades 304 and 316, structural steels up to 800 MPa, and aluminum alloys and engineering brass
  • Precision of the 6H tolerance required in the production of hydraulic housings, valve blocks, and components for high-pressure industrial valves and fittings
  • Durability thanks to HSSE steel with 5% cobalt allows 350-500 threads to be produced in structural steel with proper lubrication using tapping oil
  • Compatibility with ER40 holders and tapping heads for CNC machining centers with synchronous tapping and axial compensation
  • M32x2 general-purpose machine tap with form C directs chips correctly in both through holes and blind holes without the risk of jamming

The M32x2 HSSE machine tap is designed for machining hydraulic power components and industrial valves and fittings. The M32x2 machine tap for through holes and blind holes is not recommended for hardened steels above 45 HRC. The tap drill diameter is 30 mm.

Frequently asked questions

The M32x2 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 M32x2 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.
