Ø10.7 mm HSS metal drill bit – Morse taper MT1
Product description and key benefits
The Ø10.7 mm NWKc twist drill with an MT1 taper is designed for precision drilling in structural steels on pillar drilling machines. The Morse taper shank provides secure, self-holding seating in the spindle — eliminating the risk of the tool slipping rotationally under increased cutting torque. With a flute length of 94 mm, the Ø10.7 Morse taper drill allows through holes to be drilled in typical shop sections and sheet metal.
Key benefits of the Ø10.7 mm metal drill bit
- Direct mounting in an MT1 spindle — eliminates the drill chuck and its associated radial runout
- DIN 345 — ensures full interchangeability with drills from other manufacturers and compatibility with reduction sleeves
- Right-hand helical flutes — efficient chip evacuation from the cutting zone even when drilling holes deeper than 3×D
- Abrasion resistance — high-speed steel (HSS) provides cutting edge durability when machining structural steels with tensile strengths up to 900 N/mm²
- Overall length of 175 mm — compact construction increases system rigidity and reduces vibration during drilling
- Material versatility — drilling steel, cast iron, and aluminum — one tool for most shop tasks
The Ø10.7 Morse taper drill is used in maintenance departments for repairing and reconditioning machine components. Standard H12 hole tolerance (Ø10.700–Ø10.880 mm) is sufficient for most through holes; close fits are achieved by reaming.

Drilling blind holes
When drilling blind holes with the Ø10.7 mm drill, allow for the drill point cone — the usable depth is approximately 3 mm less than the set depth. For holes deeper than 32 mm (3×D), retract the drill every 16 mm to clear chips from the flutes.
Material compatibility of the Ø10.7 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 Ø10.7 mm drill bit
In S235/S355 structural steels, spot drilling is not necessary — the 118° angle provides self-centering. Spot drilling with an NC 90° drill is recommended when drilling on milled surfaces, castings with machining allowance, or difficult-to-machine materials.
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 Ø10.7 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.
