Ø95 mm HSS metal drill bit – Morse taper MT6
Product description and key benefits
The Ø95 mm metal drill bit is a specialist tool for machining very large-diameter holes on radial drilling machines and boring machines with an MT6 Morse taper spindle. At a diameter of 95 mm, axial force in structural steel exceeds 20 kN, and torque reaches 200 Nm — many times more than typical pillar drilling machines can handle. The Ø95 Morse taper drill bit is used exclusively for industrial machining: heavy machinery manufacturing, shipyards, and valve manufacturing plants.
Key benefits of the Ø95 mm metal drill bit
- MT6 taper — direct mounting — eliminates the drill chuck as a source of radial runout and tool slippage
- HSS cutting edge, 63–65 HRC — hardness that ensures stable cutting of steels with tensile strengths up to 900 N/mm² throughout the interval between sharpenings
- Right-hand helical flutes — effective chip evacuation from the cutting zone — essential when drilling holes deeper than 2×D
- Compact 540 mm design — shorter tool overhang provides greater rigidity and less vibration
- Repeated reconditioning — the HSS cutting edge can be resharpened 8–12 times while retaining its geometry — at l2 = 290 mm, the resharpening allowance is approximately 36 mm
- Sleeve compatibility — use on drilling machines with MT5 to MT6 spindles using reduction sleeves
The Ø95 Morse taper drill bit is used exclusively in heavy machinery manufacturing — turbine units, rolling mills, presses, and mining machinery. Typical applications include holes in thick plates (>50 mm), housing castings, and load-bearing frame components. Tolerance grade H12 (Ø95.000–Ø95.350 mm); more accurate holes are produced exclusively by boring.

REDUCTION SLEEVES COMPATIBLE WITH THE Ø95 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 95 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 Ø95 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 Ø95 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 95 mm in steel exceeds 200 Nm.
At least two: 1) a Ø25–30 mm pilot hole, 2) the final Ø95 mm drill bit. For diameters above 90 mm, consider three stages: pilot Ø25 → intermediate Ø50 → final Ø95 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.
