Ø65 mm HSS metal drill bit – Morse taper MT5
Product description and key benefits
The Ø65 mm NWKc twist drill with an MT5 taper falls within a range where every drilling operation requires careful planning — from pilot hole selection and cutting parameters to the cooling system. The MT5 taper is the largest taper used in standard shop drilling machines. With a flute length of 245 mm, the Ø65 Morse taper drill allows drilling in thick plates with a single tool.
Key benefits of the Ø65 mm metal drill bit
- Secure MT5 taper mounting — the self-holding taper conforming to DIN 345 transmits cutting torque without intermediate components — no drill chuck is required
- HSS steel resistant to temperatures up to 600°C — the cutting edge retains its working hardness at the cutting speeds recommended for structural steels and cast iron
- Flute length 245 mm — enables drilling through holes in components up to 235 mm thick without extensions
- Self-centering 118° geometry — eliminates spot drilling on flat surfaces — saves time in batch production
- Diameter tolerance class h8 — the predrilled hole is ready for reaming to H7 without an additional boring bar pass
- Full interchangeability according to DIN 345 — identical taper dimensions regardless of manufacturer — the drill can be replaced without adjusting the machine
The Ø65 mm Morse taper drill is used in the production of drive, transmission, and hydraulic cylinder components. Holes for bearing bushings and valve seats require preliminary drilling with a twist drill before boring. H12 tolerance, Ø65.000–Ø65.300 mm.

REDUCTION SLEEVES COMPATIBLE WITH THE Ø65 MM DRILL BIT:
| ✓ | MT5 → MT6 — for a spindle with an MT6 socket |
| ✓ | MT5 → MT4 — not recommended (socket capacity below the operating load) |
| ✓ | MT5 drill drift — for removing the drill bit from the spindle |

|---|---|---|---|---|---|
| P Steel | Structural steel up to 900 N/mm² | 11÷20 | 0.32 | 54÷98 | 17÷31 |
| K Cast iron | Gray cast iron GG20–GG30 | 13÷16 | 0.32 | 64÷78 | 20÷25 |

Minimum machine power for diameters of 50+ mm
The Ø65 mm drill requires a machine with a power rating above 4 kW and an MT5 or larger spindle. Torque when drilling S355 steel reaches 130 Nm — pillar drilling machines rated below 3 kW will not provide stable cutting conditions.
Material compatibility of the Ø65 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 Ø65 mm drill bit
Yes — gray cast iron (GG20–GG30) and ductile cast iron (GGG40) are well suited to HSS drills. Short, brittle chips are easier to evacuate from the flutes than steel chips. Dry drilling with a compressed air blast is possible.
H12 tolerance as standard. Reaming or boring is required for H7 or tighter fits — a twist drill cannot achieve these tolerances without finishing.
At least 4 kW of motor power and an MT5 or larger spindle. When drilling S355 steel, torque at the drill reaches 162 Nm — bench and magnetic drilling machines do not provide sufficient rigidity. The optimal machine is a box-column or radial drilling machine with power feed.
