Drill bit AWTools AW40339, metal/wood drilling, 60 g weight

The AWTools AW40339 drill bit is a general-purpose bit designed for standard drilling tasks in wood and metal. Made of high-quality carbon steel and weighing 60 g, this bit is compatible with handheld and stationary drills. Its threaded tip helps start holes precisely, while the hexagonal shank improves retention in chucks and quick-change adapters. The spiral flute is shaped for efficient chip evacuation, making it suitable for common fastening and assembly work in home workshops and light professional use.

Advantages

The carbon steel construction provides a balance of hardness and toughness for routine drilling applications. A threaded tip reduces wandering at the start of a hole, improving accuracy without the need for pilot holes. The hexagonal shank prevents slipping and reduces the chance of the bit falling out during operation. Spiral flutes enable faster removal of wood and metal chips, helping maintain cutting efficiency and reducing heat build-up in typical use conditions.

Suitable for

• Drilling holes in wood, veneered chipboard and plywood
• Light metal drilling and general fastening tasks
• Home improvement and workshop assembly work
• Use with handheld drills and drill presses

How to use

Secure the AWTools AW40339 drill bit in the drill chuck or hex adapter, ensuring it is tightened to prevent slipping. Select an appropriate drill speed for the material: lower speeds for metals and higher speeds for wood. Position the threaded tip against the workpiece and apply steady pressure until the tip engages, then continue drilling with moderate, consistent force. Withdraw the bit periodically in longer holes to clear chips and avoid overheating. After use, wipe clean and store dry to prevent corrosion.

Usage recommendations

For best results, use cutting lubricant when drilling metal, and choose drill speeds and feed rates appropriate to the material. Inspect the bit periodically for wear and replace when the tip or flute is visibly worn to maintain hole quality and safety.
