Ø9.2 mm HSS metal drill bit – Morse taper MT1
Product description and key benefits
The Ø9.2 mm twist drill with an MT1 taper shank solves the problem of tool slippage in a three-jaw chuck under full load. The Morse taper is self-holding — the higher the cutting torque, the more securely it seats in the spindle. The Ø9.2 Morse taper drill for a diameter of 9.2 mm ensures stability even during prolonged batch drilling at a single workstation.
Key benefits of the Ø9.2 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 = 162 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 Ø9.2 Morse taper drill is used in maintenance departments for repairing and reconditioning machine components. Standard H12 hole tolerance (Ø9.200–Ø9.350 mm) is sufficient for most through holes; close fits are achieved by reaming.

Drilling blind holes
When drilling blind holes with the Ø9.2 mm drill, allow for the drill point cone — the usable depth is approximately 3 mm less than the set depth. For holes deeper than 27 mm (3×D), retract the drill every 13 mm to clear chips from the flutes.
Material compatibility of the Ø9.2 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 Ø9.2 mm drill bit
The maximum drilling depth is the flute length l2 = 81 mm minus the drill point length (approximately 3 mm). The effective usable depth is therefore approximately 78 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.
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.
