Ø96 mm HSS metal drill bit – Morse taper MT6

Product description and key benefits

The Ø96 mm metal drill bit with an MT6 Morse taper shank to DIN 345 is designed for drilling holes in castings, foundation plates, and machine housings up to 260 mm thick. The MT6 taper transmits the full torque required when machining diameters of 77–100 mm. The Ø96 Morse taper drill bit requires a staged approach: spot drilling → pilot Ø25–30 mm → final Ø96 mm drill bit.

Key benefits of the Ø96 mm metal drill bit

  • Morse taper MT6 — self-holding mounting in the spindle eliminates slipping under full cutting torque
  • HSS high-speed steel — the cutting edge retains its working hardness up to 600°C in structural and low-alloy steels
  • Full compliance with DIN 345 — ensures interchangeability and compatibility with reduction sleeves and Morse taper spindles
  • 118° point angle — versatile cutting geometry performs well in structural and medium-hard steels, cast iron, and aluminum
  • Diameter tolerance h8 — repeatable hole size within a tolerance class that ensures consistent parameters in series production
  • Resharpenable cutting edges — repeated sharpening on a grinder while maintaining the 118° angle and cutting edge symmetry

The Ø96 mm Morse taper drill bit is a tool for plants equipped with heavy machine tools — radial drilling machines, boring machines, and machining centers. Typical applications: holes for bearing bushings, valve seats, and process holes in castings. Tolerance H12 (Ø96.000–Ø96.350 mm).

REDUCTION SLEEVES COMPATIBLE WITH THE Ø96 MM DRILL BIT:

✓ MT6 → MT5 — not recommended (socket capacity below the operating load)
✓ MT6 → MT4 — not recommended (socket significantly undersized for the load)
✓ MT6 drill drift — for removing the drill bit from the spindle

Pressurized coolant is mandatory

At a diameter of 96 mm, drilling without pressurized coolant is not permitted. Minimum coolant system flow rate: 10 l/min, emulsion concentration 8–10%. Lack of cooling leads to cutting-edge overheating, hardening of the material in the cutting zone, and drill breakage.

Material compatibility of the Ø96 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 50%, pilot drilling required)
▲ Aluminum and Al alloys (increased Vc, emulsion cooling)
✗ Hardened steels above 45 HRC

Frequently asked questions about the Ø96 mm drill bit

At least 7 kW with an MT6 Morse taper spindle and power feed. Radial drilling machines with an arm length of at least 1200 mm. Torque at a diameter of 96 mm in steel exceeds 200 Nm.

At least two: 1) a Ø25–30 mm pilot hole, 2) the final Ø96 mm drill bit. For diameters above 90 mm, consider three stages: pilot Ø25 → intermediate Ø50 → final Ø96 mm.

Pressurized coolant is mandatory: emulsion concentration 8–10%, minimum flow rate 10 l/min. Lack of cooling leads to cutting-edge overheating, hardening of the cutting zone, and tool breakage.
