Ø58 mm HSS metal drill bit – Morse taper MT5
Product description and key benefits
The Ø58 mm metal drill bit with an MT5 Morse taper shank to DIN 345 is designed for holes that cannot be made with hole saws because of the required drilling depth. A hole saw works to a depth of 30–50 mm, while the Ø58 twist drill reaches 235 mm. The Ø58 Morse taper drill bit is the only option for drilling into solid material in thick foundation plates and housing castings.
Key benefits of the Ø58 mm metal drill bit
- Morse taper MT5 — 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 Ø58 mm Morse taper drill is used in heavy machinery manufacturing to produce holes in castings, machine bodies, and thick plates. In shipyards, it is used to machine hull components and hatch cover mechanisms. H12 tolerance (Ø58.000–Ø58.300 mm); more precise holes require boring.

REDUCTION SLEEVES COMPATIBLE WITH THE Ø58 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 |

Mandatory pilot drilling
The Ø58 mm drill should not be used without a pilot hole. Drill a pilot hole using a Ø20–25 mm drill — this reduces axial force by 40–50% and eliminates engagement of the chisel edge responsible for vibration. At depths greater than 116 mm (2×D), use peck drilling with retraction every 30–40 mm and ample coolant (min. 8% emulsion, 8 l/min).
Material compatibility of the Ø58 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 Ø58 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 145 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.
