Ø36 mm HSS metal drill bit – Morse taper MT4

Product description and key benefits

The Ø36 mm twist drill with an MT4 taper shank conforming to DIN 345 is designed for drilling mounting holes in foundation plates, flanges, and machine housings. At a diameter of 36 mm, the axial force and torque require a stable machine platform — a pillar or box-column drilling machine with power spindle feed. The Ø36 Morse taper drill with a flute length of 195 mm enables drilling through holes in components with thicknesses commonly encountered in machine building.

Key benefits of the Ø36 mm metal drill bit

  • Direct mounting in an MT4 spindle — eliminates the drill chuck as a source of runout and slippage
  • Flute length 195 mm — drilling through holes in workpieces up to 180 mm thick in a single pass
  • DIN 345 — identical taper dimensions regardless of manufacturer — full interchangeability
  • Type N right-hand helical flutes — a compromise between web rigidity and flute capacity
  • h8 diameter fit — preliminary holes for reaming to H7 without additional boring
  • Extended tool life with emulsion cooling — coolant increases cutting edge life by up to a factor of 2.5 compared with dry drilling

The Ø36 mm Morse taper drill is used in facilities where large hole diameters are an everyday requirement — manufacturing frames, chassis, machine bodies, and housings. Holes meet H12 tolerance (Ø36.000–Ø36.250 mm); fits for pins require reaming to H7.

REDUCTION SLEEVES COMPATIBLE WITH THE Ø36 MM DRILL BIT:

✓ MT4 → MT5 — for a spindle with an MT5 socket
✓ MT4 → MT3 — for a spindle with an MT3 socket
✓ MT4 drill drift — for removing the drill bit from the spindle

Deep-hole drilling (over 3×D)

When drilling holes deeper than 108 mm (3ר36), periodically retract the drill every 1–1.5×D to remove chips. Use ample emulsion cooling (minimum concentration of 6–8%). Reduce the feed by 30–50% from nominal values.

Material compatibility of the Ø36 mm drill bit

Range of workpiece materials and application limitations

✓ Structural steel (S235, S355) up to 900 N/mm²
✓ Gray and ductile cast iron (GG20, GGG40)
✓ Low-carbon and medium-alloy steel
▲ Stainless steel (Vc reduced by 40%, ample coolant)
▲ Aluminum and Al alloys (emulsion coolant required)
✗ Hardened steels above 45 HRC

Frequently asked questions about the Ø36 mm drill bit

When drilling S355 steel with a Ø36 mm drill, the torque is approximately 90 Nm. This requires a drilling machine with a minimum power rating of 2.2 kW and power spindle feed.

For a drilling machine with an MT5 spindle: MT4→MT5 sleeve. For a smaller MT3 spindle: MT4→MT3 sleeve (check that the operating load does not exceed the socket capacity). For removal: MT4 drill drift.

Depth greater than 3×D (108 mm): reduce feed by 30–50%, retract every 1×D, and use a 6–8% emulsion at a minimum flow rate of 6 l/min. Peck drilling prevents chips from jamming in the flutes.
