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 M10x0.5 tap has a reduced shank to DIN 374: diameter 7 mm, square size 5.5 mm.

M10x0.5 INOX machine tap – with a metric fine thread

The HSSE series designed for manufacturing engineers and CNC operators working with precision connections includes the M10x0.5 INOX machine tap for metric fine threads. The 6H tolerance in accordance with DIN 374 guarantees the dimensional repeatability required in the manufacture of hydraulic and pneumatic components with stringent leak-tightness requirements. The thread pitch of 0.5 mm provides more threads per unit length, increasing the load capacity of the connection and resistance to self-loosening. Its HSSE steel construction with 5% cobalt guarantees a hardness of 66 HRC and long cutting edge life in stainless steels.

Key features of the M10x0.5 INOX tap

  • Compliance with DIN 374 for metric fine threads ensures standardized dimensions and full interchangeability with tools from European manufacturers
  • Designed for hydraulic connections and pneumatic components requiring high leak-tightness thanks to the increased number of threads per unit length
  • 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 ER16 holders and tapping heads for CNC machining centers with synchronous tapping and axial compensation
  • M10x0.5 general-purpose machine tap with form C directs chips correctly in both through holes and blind holes

The M10x0.5 HSSE machine tap is designed for machining structural steels up to 800 MPa, 304 and 316 austenitic stainless steels, and aluminum alloys. The M10x0.5 machine tap for through and blind holes is not recommended for hardened steels above 45 HRC. The tap drill diameter is 9.5 mm.

Frequently asked questions

The M10x0.5 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 M10x0.5 thread is 9.5 mm. The hole tolerance range should be 9.4–9.6 mm. A hole at the lower tolerance limit produces a fuller thread profile, while one at the upper limit reduces tapping torque.

The M10x0.5 tap works with ER20 holders and tapping chucks with axial compensation. Synchronized heads with automatic tool change capability are recommended for CNC machines.
