Drill bit AWTools AW40356 — metal/wood drilling, weight 283 g

The AWTools AW40356 drill bit is a general-purpose bit for handheld and machine drills, designed for metal and wood drilling. Made of high quality carbon steel, this bit combines a threaded tip for precise centring with a spiral flute that accelerates chip removal. A hexagonal shank secures the bit in standard chucks and quick-change holders. The listed weight is 283 g, and the geometry is intended for common workshop tasks including maintenance and repair work.

Advantages

The carbon steel construction offers strength and durability for a range of drilling operations. The threaded tip reduces walking at the start of a hole, improving accuracy on both wood and thin metal. Spiral flutes evacuate chips efficiently to maintain cut quality and reduce heat buildup. The hexagonal shank minimises slippage in quick-change chucks and improves torque transfer during heavier drilling.

Suitable for

• Drilling in solid wood, plywood and veneered chipboard
• Light to medium metal drilling where a general-purpose bit is acceptable
• Workshop maintenance and repair tasks with handheld or machine drills
• Applications requiring fast chip removal and secure bit retention

Key specifications

• Material: high quality carbon steel
• Tip type: threaded centre tip for precise start
• Shank: hexagonal shank for secure clamping
• Flute: spiral flute design for fast chip evacuation
• Intended materials: wood, veneered chipboard, plywood, and typical thin metals
• Weight: approximately 283 g

How to use

Select a drill and chuck or quick-change holder compatible with a hexagonal shank. Secure the bit firmly in the chuck, set an appropriate rotational speed for the material being drilled, and align the threaded tip with the planned drilling point. Apply steady, even pressure until the threaded tip engages and the hole begins to form, then continue drilling while allowing chips to evacuate. Withdraw the bit periodically on deep holes to clear chips and reduce heat.

Usage recommendations

For best results, use appropriate cutting speeds and light to moderate feed pressure depending on material hardness. When drilling metal, use cutting fluid to extend bit life and improve finish. Inspect the bit for wear before use and replace if the cutting edges are worn or the tip is damaged.
