Description
Overview:
The Dormer A120 HSS Stub Drill is a short-series twist drill bit for accurate drilling in metal and plastics where rigidity and access matter. Made from high-speed steel (HSS), it balances toughness and wear resistance for dependable service in the workshop and on site. With a 5.00 mm diameter, 62 mm overall length, and 26 mm working (flute) length, it is well suited to portable drills, drill presses, turrets, and automatic lathes. A split-point tip helps the drill start cleanly and stay on line, reducing wander on curved or hard surfaces. The straight shank fits standard chucks and collet systems. Product designation: Dormer A120, size A1205.0. Manufacturer part number: DORA120500.
Key Features:
- 5.00 mm diameter for general-purpose hole making across a wide range of materials
- Short-series length (OL 62 mm, WL 26 mm) improves rigidity and reduces deflection in tight spaces
- HSS construction for durability, edge retention, and consistent performance under heat
- Split-point geometry for easy starting, accurate location, and reduced need for centre punching
- Straight shank compatible with standard 3-jaw chucks and common collet systems
- Effective on mild steel, aluminium, brass, copper, and many engineering plastics
- Suitable for hand-held drilling, drill presses, turrets, and automatic lathes
- Re-sharpenable cutting edges to extend service life when maintained correctly
Typical Applications:
General fabrication, maintenance, and assembly work, including bracketry, panels, fixtures, and precision components. Ideal as the tapping drill for M6 threads, as well as for pilot and clearance holes in ferrous and non‐ferrous metals. Useful in toolrooms, production lines, and site-based tasks where a compact, rigid drill minimises breakage and improves positional accuracy.
