Ø60 mm HSS metal drill bit – Morse taper MT5
Product description and key benefits
The Ø60 mm HSS metal drill bit with an MT5 Morse taper withstands heavy-duty loads — axial force in structural steel reaches well over ten kN, and torque exceeds 80 Nm. Under these conditions, the quality of tool seating in the spindle determines operational safety and cutting-edge life. The Ø60 Morse taper drill bit with an MT5 taper provides contact over a surface more than 44 mm in diameter.
Key benefits of the Ø60 mm metal drill bit
- MT5 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 422 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 = 235 mm, the resharpening allowance is approximately 29 mm
- Sleeve compatibility — use on drilling machines with MT4 to MT6 spindles using reduction sleeves
The Ø60 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 (Ø60.000–Ø60.300 mm); more precise holes require boring.

REDUCTION SLEEVES COMPATIBLE WITH THE Ø60 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 Ø60 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 120 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 Ø60 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 Ø60 mm drill bit
Yes — it is required. A Ø20–25 mm pilot hole eliminates cutting by the chisel edge, which at a diameter of 60 mm generates 60–70% of the total axial force and severe vibration.
1) Drill a Ø20–25 mm pilot hole. 2) Check runout in the spindle (maximum 0.03 mm). 3) Clamp the workpiece rigidly. 4) Use power feed — manual feed causes uneven pressure and resonance.
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.
