Ø36.5 mm HSS metal drill bit – Morse taper MT4
Product description and key benefits
The Ø36.5 mm HSS metal drill bit with an MT4 Morse taper shank is designed for heavy-duty hole machining in structural and alloy steels. DIN 345 specifies an MT4 taper for diameters of 32–50 mm, providing a compromise between shank size and load capacity. The Ø36.5 Morse taper drill bit requires a machine tool with a power rating of at least 2.2 kW and a Morse taper spindle.
Key benefits of the Ø36.5 mm metal drill bit
- Self-holding taper shank — MT4 transmits full torque to the cutting edges without intermediate components
- HSS with a hardness of 63–65 HRC — stable cutting of materials with tensile strengths up to 900 N/mm² without loss of sharpness
- Overall length of 344 mm — proportional to the drilling diameter — provides a balance between reach and rigidity
- General-purpose 118° geometry — suitable for most materials encountered in shop machining
- Sleeve compatibility — use on drilling machines with MT3 to MT5 spindles using reduction sleeves
- Repeated resharpening — HSS steel allows the cutting edge to be restored without loss of cutting properties
The Ø36.5 mm Morse taper drill bit is used for heavy-duty machining — manufacturing machine frames, special-purpose vehicle chassis, and components of metallurgical equipment. The tool operates under conditions where hole quality depends on clamping rigidity and stable cutting parameters. Tolerance grade H12, Ø36.500–Ø36.750 mm.

Minimum machine tool power
The Ø36.5 mm drill requires a drilling machine with at least 2.2 kW of power and power spindle feed. Stability is difficult to maintain with manual feed — uneven pressure leads to vibration and accelerated cutting edge wear. A box-column or radial drilling machine is recommended.
Material compatibility of the Ø36.5 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 40%, ample coolant)
▲ Aluminum and Al alloys (emulsion coolant required)
✗ Hardened steels above 45 HRC
Frequently asked questions about the Ø36.5 mm drill bit
For a drilling machine with an MT5 spindle: MT4→MT5 sleeve. For a smaller MT3 spindle: MT4→MT3 sleeve (check that the operating load does not exceed the socket capacity). For removal: MT4 drill drift.
Depth greater than 3×D (109 mm): reduce feed by 30–50%, retract every 1×D, and use a 6–8% emulsion at a minimum flow rate of 6 l/min. Peck drilling prevents chips from jamming in the flutes.
1) Clean the taper and spindle socket. 2) Check runout (maximum 0.03 mm). 3) Replace the drill if the taper is damaged or worn. 4) Do not stack reduction sleeves (e.g., MT4→MT3→MT5).
