Ø16 mm HSS metal drill bit – Morse taper MT2
Product description and key benefits
The Ø16 mm NWKc twist drill with an MT2 taper falls within a diameter range where the torque generated during cutting exceeds the capacity of a typical drill chuck. DIN 345 specifies an MT2 taper with a diameter of 17.78 mm for these drill diameters — large enough to transmit the full load without slippage. With a flute length of 120 mm, the Ø16 Morse taper drill allows through drilling in standard steel sections.
Key benefits of the Ø16 mm metal drill bit
- Direct mounting in an MT2 spindle — eliminates the drill chuck as a source of runout and slippage
- Flute length 120 mm — drilling through holes in workpieces up to 105 mm thick in a single pass
- DIN 345 — identical taper dimensions regardless of manufacturer — full interchangeability
- Type N right-hand helical flutes — a compromise between web rigidity and flute capacity
- h8 diameter fit — preliminary holes for reaming to H7 without additional boring
- Extended tool life with emulsion cooling — coolant increases cutting edge life by up to a factor of 2.5 compared with dry drilling
The Ø16 mm Morse taper drill is used in facilities where drilling holes is a daily operation — steel fabrication plants, machinery service shops, and toolrooms. Secure taper mounting allows hours of operation without checking the chuck. H12 hole tolerance, Ø16.000–Ø16.180 mm.

|---|---|---|---|---|---|
| P Steel | Structural steel up to 900 N/mm² | 11÷20 | 0.16 | 219÷398 | 35÷64 |

Mounting the drill in the spindle
Before mounting the Ø16 mm drill, remove chips, oil, and contaminants from the taper and spindle socket. Residue between the contact surfaces causes radial runout and can damage the spindle socket.
Material compatibility of the Ø16 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 Ø16 mm drill bit
A pillar or box-column drilling machine with an MT2 spindle and a minimum power rating of 0.75–1.5 kW. Bench drilling machines with a drill chuck are not recommended — they cannot transmit the torque generated at a diameter of 16 mm.
It depends on the specific bolted joint. For metric coarse-thread bolts, the clearance hole diameter according to ISO 273 is 0.5–1 mm larger than the nominal thread diameter.
Use cooling with a 5–8% emulsion, do not exceed the recommended cutting parameters, and resharpen the tool before it becomes completely dull. Clean taper and spindle socket surfaces reduce runout — the main cause of accelerated wear.
