Ø9.6 mm HSS metal drill bit – Morse taper MT1
Product description and key benefits
The Ø9.6 mm twist drill with an MT1 Morse taper is an alternative to straight-shank drills wherever a drill chuck does not provide sufficient clamping rigidity. Direct mounting in the spindle of a pillar drilling machine eliminates the intermediate link — the chuck — which can become a source of runout and slippage during intensive use. The Ø9.6 Morse taper drill is particularly suitable for metalworking shops and toolrooms, where hole position accuracy matters when fitting pins and bushings.
Key benefits of the Ø9.6 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 87 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 = 87 mm, the resharpening allowance is approximately 10 mm
The Ø9.6 mm Morse taper drill is used in metalworking shops for bolt and dowel holes in steel components. In batch production, it provides repeatable dimensional accuracy within tolerance class H12 (Ø9.600–Ø9.750 mm). H7 fits require finish reaming.

Drilling blind holes
When drilling blind holes with the Ø9.6 mm drill, allow for the drill point cone — the usable depth is approximately 3 mm less than the set depth. For holes deeper than 28 mm (3×D), retract the drill every 14 mm to clear chips from the flutes.

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 Ø9.6 mm drill bit
The Ø9.6 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.
The maximum drilling depth is the flute length l2 = 87 mm minus the drill point length (approximately 3 mm). The effective usable depth is therefore approximately 84 mm.
