## Long description

The Drill bit DORMER spiral twist with cylindrical shank DORMER 8211130450 is a general-purpose high-speed steel twist drill designed for metalworking and common drilling operations. It features a cylindrical shank that fits standard chucks and a spiral (twist) flute geometry that evacuates chips efficiently while maintaining drill guidance for accurate through and blind holes. This drill is suited for workshop, industrial and maintenance environments where a reliable, straight-fluted twist drill is required for routine hole-making tasks in a variety of ferrous and non-ferrous materials.
Advantages
The spiral twist geometry ensures consistent chip removal and reduced clogging during drilling. The cylindrical shank provides secure seating in standard drill chucks and holders, enabling stable rotation and precision. Ground flutes and cutting lips deliver accurate hole position and straightness with controlled cutting action. The construction and material selection promote longevity under normal operating speeds and standard coolant or lubrication practices.
Suitable for
Drilling through and blind holes in metalwork
General workshop and maintenance drilling
Use in portable drills and bench drills with standard chucks
Applications requiring repeatable, accurate hole-making
Key specifications
Drill type: spiral twist (straight fluted) drill
Shank: cylindrical shank for standard chucks
Material compatibility: ferrous and non-ferrous metals
Typical use: through and blind hole drilling
Geometry: ground cutting lips and spiral flutes for chip evacuation
How to use
Secure the drill bit in the chuck so the cylindrical shank is fully supported and tightened to prevent slippage. Select appropriate speed and feed for the workpiece material; use reduced speeds for harder metals and increase speed for softer non-ferrous materials. Apply cutting fluid or coolant when drilling metals to extend tool life and improve chip evacuation. Begin drilling with a center punch or pilot hole for precise positioning when required, and retract periodically to clear chips on deep holes.
Usage recommendations
For best results, match drill speed and feed to the material being drilled, keep the tool properly sharpened, and use suitable lubrication. Inspect the drill for wear or damage before use and replace when cutting edges are dull to maintain hole accuracy and reduce workpiece damage.
