## Summary description

Irwin twist drill bit with 4.5 mm diameter, single piece (model 10502215). Designed for drilling in common materials with a standard twist geometry that ensures chip evacuation and straight drilling. Suitable for hand drills and drill presses for general-purpose tasks such as metal, wood, and plastic drilling where a 4.5 mm hole is required.

## Long description

Irwin twist drill bit with a 4.5 mm diameter, single piece. The bit features standard twist geometry for efficient chip evacuation and accurate, straight drilling. It is intended for general-purpose use in a variety of common materials and is compatible with both hand drills and drill presses. The 4.5 mm size provides a precise hole for fastening, doweling, or pilot drilling tasks.
Advantages
This twist drill bit delivers consistent hole quality thanks to its conventional flute design that promotes reliable chip removal and reduced walking at the point of contact. Its cylindrical shank ensures secure clamping in standard chucks and drill press holders. The bit is versatile across metal, wood and plastic and also performs well in sheet metal. When used with appropriate speeds and feeds it gives repeatable results for everyday workshop and site tasks.
Suitable for
Drilling holes in mild steel and general metalwork
Creating pilot holes in wood for screws and dowels
Drilling plastics and composite panels
Working with sheet metal where a 4.5 mm hole is required
Key specifications
Drill type: twist drill
Diameter: 4.5 mm
Overall length: 80 mm
Shank type: cylindrical
Package quantity: 1 piece
Compatible with hand drills and drill presses
How to use
Secure the drill bit in the chuck or holder ensuring the cylindrical shank is fully seated and tightened. Select a drilling speed appropriate for the material—higher speeds for wood and plastics, moderate speeds for mild steel and sheet metal. Start drilling with light pressure to establish the hole and then apply steady feed force while allowing the bit to clear chips. Withdraw periodically for chip removal in deep holes and keep the workpiece clamped to avoid movement.
Usage recommendations
For drilling stainless steel, use cutting fluid or coolant to reduce heat and prolong tool life; for general metalworking, moderate speeds and steady feed improve hole quality. If working extensively with stainless or hardened materials, consider using specialty cobalt or high-speed steel variants designed for those conditions.
