Drill bit AWTools AW42705, metal/wood drilling, length unspecified, weight 25 g

AWTools AW42705 drill bit is a compact, lightweight tool for general drilling in metal and wood. Made of high-quality carbon steel with a tungsten carbide blade rated at 90 HRC and a titanium nitride (TiN) coating, this bit is built for enhanced wear resistance and longer cutting life. Weighing approximately 25 g, it is suitable for use with compatible handheld and bench drills where a small, easy-to-handle bit is required for routine maintenance, assembly and light construction tasks.

Advantages

The combination of a carbon steel body, a 90 HRC tungsten carbide cutting edge and a TiN coating provides improved hardness, reduced friction and extended durability compared with uncoated bits. Its low weight and compact form factor make it easy to manoeuvre in confined spaces and more comfortable for repetitive drilling. The TiN coating also helps maintain sharpness and reduces heat build-up during cutting.

Suitable for

• Drilling through soft metals such as aluminium
• General wood drilling for fittings and fixtures
• Routine maintenance and assembly work
• Light construction and carpentry tasks
• Precision drilling in repair and hobby projects

Key specifications

• Material: carbon steel body with tungsten carbide cutting edge
• Cutting edge hardness: 90 HRC
• Coating: titanium nitride (TiN) for reduced friction and wear resistance
• Weight: approximately 25 g
• Application: suitable for metal and wood drilling; compatible with standard drill chucks
• Recommended operation: low speed, non-impact drilling with appropriate coolant

How to use

Install the AWTools AW42705 firmly in the drill chuck and ensure proper alignment before starting. Select a low rotational speed and disable hammer/impact mode; use a suitable coolant or cutting fluid when drilling metals to reduce heat and prolong tool life. Apply steady, moderate pressure and allow the cutting edge to do the work—avoid excessive force which can cause overheating or premature wear. Clear chips regularly and retract periodically to help evacuate debris when drilling deeper holes.

Usage recommendations

For best results, use the bit at low speed in non-impact mode with appropriate coolant when working on metals; for wood, moderate speed without impact is suitable. Avoid high-speed or impact drilling to preserve the carbide edge and TiN coating.
