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 M36 x4 tap has a reduced shank to DIN 376: diameter 28 mm, square size 22 mm.

M36 INOX machine tap – HSSE for stainless steel

The M36 INOX machine tap is designed for precise tapping of holes with a diameter of 36 mm and a coarse pitch of 4 mm in stainless and structural steels. HSSE high-speed steel with 5% added cobalt guarantees a hardness of 66 HRC and long cutting-edge life even when machining difficult-to-machine materials. Form C with straight flutes provides universal use in through holes and blind holes. Tolerance 6H in accordance with DIN 376 confirms high manufacturing quality. The M36 HSSE machine tap with a long shank is designed for departments handling series production of mechanical components.

Key features of the M36 universal tap

  • Long shank to DIN 376 provides increased clamping rigidity and eliminates vibration at the high cutting torques typical of large diameters
  • Compliance with DIN 376 confirms quality and ensures standardized long-shank dimensions compatible with European tool 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 ER40 holders and tapping heads for CNC machining centers with synchronous tapping and automatic tool changing
  • M36 machine tap for through holes and blind holes with form C allows both hole types to be tapped with a single tool without the risk of jamming

The M36 universal machine tap is used in steel structures and industrial hydraulic systems requiring durable threaded connections. The M36 HSSE machine tap is suitable for manufacturing fitting components. The tap drill diameter for the M36 thread is 32 mm for the coarse thread with a pitch of 4 mm.

Frequently asked questions

The M36 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 M36 thread is 32 mm. The hole tolerance zone should be within the range of 31.9–32.1 mm. A hole at the lower tolerance limit produces a fuller thread profile, while a hole at the upper limit reduces tapping torque.

The M36 tap works with ER40 holders and tapping chucks with axial compensation. Synchronized heads with automatic tool change capability are recommended for CNC machines.
