Ø5.3 mm HSS metal drill bit – Morse taper MT1
Product description and key benefits
The Ø5.3 mm twist drill with an MT1 Morse taper achieves higher hole accuracy than comparable straight-shank drills — direct mounting in the spindle shortens the torque transmission path and reduces radial runout. The tool is designed for stationary drilling machines: pillar machines, bench machines with an MT1 spindle, and box-column machines. The Ø5.3 Morse taper drill with a flute length of 52 mm is sufficient for holes in sheet metal and sections of typical shop thicknesses.
Key benefits of the Ø5.3 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 = 133 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 Ø5.3 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 (Ø5.300–Ø5.420 mm). H7 fits require finish reaming.

Coolant for drilling steel
The Ø5.3 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 Ø5.3 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 Ø5.3 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 = 52 mm minus the drill point length (approximately 2 mm). The effective usable depth is therefore approximately 50 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.
