Drill bit AWTools AW40952, model AW40952, weight 190 g

AWTools AW40952 is a high-speed steel (HSS) drill bit with an aluminium chromium nitride (AlCrN) coating and a blackened finish, weighing 190 g. The spiral flute geometry and laser-marked size engravings make it suitable as a replacement or spare bit for compatible drills used in workshops and home projects. Designed for drilling non-ferrous metals, thin-walled steel sheets and plastics, this AWTools model provides a balance of wear resistance and cutting performance for general-purpose drilling tasks.

Advantages

The AlCrN coating increases surface hardness and heat resistance, extending tool life in intermittent and continuous drilling operations. The HSS core maintains toughness to resist chipping, while the spiral design promotes faster chip evacuation and a cleaner hole finish. Laser-marked engravings let the operator verify hole size during use, reducing the need for repeated measurements. The bit’s geometry allows drilling without pre-drilling in many materials specified by the manufacturer.

Suitable for

• Drilling non-ferrous metals such as aluminum and brass
• Working with thin-walled steel sheets and metal panels
• Processing plastics and composite materials
• General workshop repairs and home improvement projects
• Replacing worn or missing drill bits in a compatible drill chuck

Key specifications

• Material: High-speed steel (HSS) core with AlCrN coating
• Coating: Aluminium chromium nitride (AlCrN), blackened finish
• Design: Spiral flute for efficient chip evacuation
• Markings: Laser-engraved size indicators on the shank
• Weight: 190 g
• Recommended materials: Non-ferrous metals, thin-walled steel sheets, plastics

How to use

Fit the AWTools AW40952 drill bit securely into a compatible drill chuck and verify proper clamping before starting. Select an appropriate rotational speed for the work material: lower speeds for harder materials and higher speeds for softer non-ferrous metals and plastics. Apply steady feed pressure and allow the spiral flute to evacuate chips; retract occasionally when drilling deeper holes to clear chips and reduce heat build-up. Use cutting fluid or lubricant as appropriate for the material to improve finish and extend tool life.

Usage recommendations

Check drill compatibility (chuck size and maximum RPM) before use. For thin-walled steel and harder alloys, reduce speed and use light, controlled feed to avoid workpiece deformation. For extended drilling sessions, pause periodically to clear chips and allow the bit to cool. Store the bit in a dry place to preserve the coating and prevent corrosion.
