## Long description

DORMER 8211130600 — spiral twist drill with cylindrical shank is a general-purpose metalworking drill designed for drilling holes in a range of materials compatible with HSS twist drills. The drill features a helical flute for efficient chip removal and a straight cylindrical shank for secure clamping in standard chucks or collets. It is suitable for use in hand-held drills and machine tools for production, maintenance and repair tasks where a conventional twist drill is required.
Advantages
The spiral flute geometry promotes continuous chip evacuation to reduce clogging and improve drilling efficiency. The cylindrical shank provides stable, concentric clamping in standard drill chucks and collets, enabling accurate hole positioning. The drill's geometry and material selection deliver consistent cutting performance across a variety of general-purpose drilling applications in metal and other compatible materials.
Suitable for
 Drilling through mild steel, iron and other machinable metals within the drill's capability
 General maintenance and repair tasks using hand-held or bench drills
 Production and workshop drilling where standard twist drills are required
 Creating pilot holes prior to reaming or tapping operations
Key specifications
 Drill type: spiral twist drill (helical flute)
 Shank: cylindrical straight shank for standard chucks and collets
 Intended materials: metals and other materials compatible with HSS twist drills
 Typical applications: general purpose drilling, maintenance, production drilling
How to use
Secure the drill in a suitably rated chuck or collet, ensuring concentric clamping of the cylindrical shank. Select an appropriate spindle speed and feed rate for the material being drilled and apply cutting fluid where recommended for metalworking to extend tool life and improve surface finish. Start drilling with steady, controlled pressure; withdraw periodically to clear chips if drilling deep holes. For bench or machine drilling maintain proper alignment and coolant flow as needed.
Usage recommendations
Use correct speeds and feeds for the material to avoid premature wear. Apply cutting fluid when drilling metals to improve chip evacuation and reduce heat. Inspect the drill for wear or damage before use and replace if cutting performance deteriorates.
