## Long description

Twist drill bit DORMER 8211130320 with a cylindrical shank is a general-purpose cutting tool intended for conventional drilling operations. It features standard twist-drill geometry suitable for through-hole and general-purpose drilling in common engineering materials. The straight, non-tapered cylindrical shank allows secure clamping in standard drill chucks and collets, enabling consistent concentricity and repeatable results when used in drills and drill presses.
Advantages
This DORMER twist drill provides reliable cutting performance with a classic two-flute geometry that balances drilling speed and chip evacuation. The cylindrical shank ensures stable grip in chucks and collets, reducing runout and improving hole quality. The tool is manufactured to conventional dimensional tolerances for predictable fit and interchangeability when replacing or regrinding bits. Its design supports straightforward sharpening and maintenance.
Suitable for
 General-purpose drilling in metals such as mild steel and non-ferrous alloys
 Drilling in common engineering plastics and wood
 Use in portable drills and bench drill presses
 Through-hole drilling and pilot hole preparation
Key specifications
 Tool type: Straight (twist) drill bit with two-flute geometry
 Shank style: Cylindrical, straight shank for chuck and collet mounting
 Intended use: General-purpose through-hole drilling
 Compatibility: Designed for use in handheld drills and drill presses
 Maintenance: Resharpenable with standard drill grinding equipment
How to use
Secure the cylindrical shank of the drill bit firmly in the drill chuck or collet, making sure the bit is seated straight to minimize runout. Select appropriate spindle speed for the material being drilled and apply steady axial feed pressure. Use cutting fluid when drilling ferrous metals to extend tool life and improve hole finish. Withdraw the bit periodically to clear chips in deep holes and to prevent chip packing around the flutes.
Usage recommendations
For best results, match cutting speed and feed to the workpiece material, use suitable coolant for metalworking, and inspect the cutting edges regularly. Replace or regrind the bit when wear or chipping degrades hole quality.
