Ø10 mm HSS metal drill bit – Morse taper MT1
Product description and key benefits
The Ø10 mm NWKc twist drill combines two features important in everyday shop work: secure taper mounting and the ability to be resharpened repeatedly. The MT1 taper provides direct contact with the spindle — without play or slippage. With a flute length of 87 mm, the Ø10 Morse taper drill allows machining of workpieces of standard thicknesses, while the 118° point angle eliminates the need for preliminary spot drilling on flat surfaces.
Key benefits of the Ø10 mm metal drill bit
- Eliminates the drill chuck — the MT1 taper seated directly in the spindle shortens the torque transmission path and reduces radial tool runout
- Heat resistance up to 600°C — the high-speed steel cutting edge retains its working hardness even at higher cutting speeds in soft and medium-hard steels
- Interchangeability to DIN 345 — identical taper dimensions across manufacturers allow drill replacement without calibrating the spindle axis
- Short design (l1 = 168 mm) — reduced tool overhang provides greater rigidity and a better hole surface finish than extended-length drills
- Holes for locating pins and bushings — the h8 tolerance grade provides a repeatable preliminary size before finish reaming to an H7 fit
- Low operating cost — can be resharpened repeatedly on a tool grinder without losing cutting geometry while maintaining the 118° angle
The Ø10 mm Morse taper drill is selected for repair and assembly work on pillar drilling machines. The tool allows fast drilling of through and blind holes in steels with tensile strengths up to 900 N/mm². H12 tolerance at Ø10.000–Ø10.150 mm provides dimensional accuracy sufficient for most bolted connections.

Drill sharpening
Sharpen the Ø10 mm drill bit on a tool grinder, maintaining the 118° point angle and cutting edge symmetry. Asymmetric sharpening enlarges the hole diameter and loads the spindle unevenly. Each sharpening reduces the flute length by approximately 1–2 mm.
Material compatibility of the Ø10 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 mm drill bit
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.
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.
