Ø10.75 mm HSS metal drill bit – Morse taper MT1
Product description and key benefits
The Ø10.75 mm NWKc twist drill is distinguished by its mounting method — the MT1 Morse taper eliminates the intermediate component between the tool and the spindle. This results in lower radial runout and improved repeatability of hole dimensions. The Ø10.75 Morse taper drill with a high-speed steel (HSS) cutting edge retains its working hardness up to 600°C, allowing drilling without the risk of tempering the cutting edge.
Key benefits of the Ø10.75 mm metal drill bit
- Self-holding Morse taper — MT1 transmits torque without slippage — essential for prolonged batch drilling
- HSS steel with a hardness of 63–65 HRC — the cutting edge retains its sharpness throughout the tool's service interval between sharpenings
- Flute length 94 mm — the maximum drilling depth allows typical shop sections and sheet metal to be machined in a single pass
- 118° point angle — self-centering in soft steels — eliminates the need for spot drilling on flat surfaces
- Diameter tolerance h8 — repeatable hole size in batch and single-part production
- Cutting edge reconditioning — repeated resharpening extends tool life — at l2 = 94 mm, the resharpening allowance is approximately 11 mm
The Ø10.75 Morse taper drill bit is most often selected for mounting holes in hollow sections, thick plates, and machine components. In toolrooms, it is used to prepare preliminary holes before reaming to a dowel pin fit. Holes are produced to tolerance class H12 (Ø10.750–Ø10.930 mm); if class H7 is required, additional reaming is necessary.

Coolant for drilling steel
The Ø10.75 mm HSS drill requires cooling with a 5–8% emulsion when drilling structural steels. Dry drilling reduces cutting edge life by 50–70% and reduces hole surface quality. Minimum coolant flow: 2 l/min.
Material compatibility of the Ø10.75 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 Ø10.75 mm drill bit
A cooling and lubricating emulsion at a concentration of 5–8% is recommended. For stainless steels, increase the concentration to 8–10%. Cast iron can be drilled dry with compressed air to remove chips.
The Ø10.75 mm NWKc drill bit with an MT1 taper mounts directly in the drill press spindle — the self-holding taper eliminates slipping under high cutting torque. A straight shank drill bit requires a drill chuck, which may not transmit the full torque during heavy use.
Yes — using an MT1→MT2 reduction sleeve. The sleeve ensures proper seating of the taper in the larger spindle socket. Use a correctly sized drill drift for removal.
