Drill bit AWTools AW40988, size unspecified, weight 220 g

AWTools AW40988 drill bit is a high-speed steel (HSS) bit with a titanium nitride (TiN) coating, supplied as a single replacement or spare for compatible rotary drilling tools. The bit is laser-marked for visible size control during drilling, weighs approximately 220 g and is designed for general-purpose drilling in non-ferrous metals, thin-walled steel sheets and plastic. Its TiN coating reduces friction and heat build-up, helping to prolong cutting life and maintain consistent hole quality.

Advantages

The HSS construction provides hardness and wear resistance suited to repeated drilling operations while the TiN coating reduces friction and improves heat dissipation. Laser-marked engravings on the shank or flute area enable easier monitoring of drilling depth and hole size. The bit can be used without pre-drilling in many applications, simplifying preparation and speeding up routine tasks. Compact weight and standard form-factor make it suitable as a direct replacement in most compatible chucks.

Suitable for

• Drilling holes in non-ferrous metals such as aluminum and brass
• Working with thin-walled steel sheets
• Drilling plastics and similar polymer materials
• Replacement or spare bit for general-purpose workshop and maintenance tasks

Key specifications

• Material: High-speed steel (HSS)
• Surface finish: Titanium nitride (TiN) coated
• Weight: approximately 220 g
• Marking: Laser-engraved size indicators for depth and hole control
• Suitable materials: non-ferrous metals, thin-walled steel, plastics

How to use

Secure the drill bit in a compatible chuck according to the drill manufacturer's instructions, ensuring correct centring and tight clamping. Use appropriate drill speed and feed for the specific material: moderate to high speed for non-ferrous metals and plastics, and lower speeds with steady feed for thin-walled steel to avoid deformation. Apply steady, even pressure and allow the coated cutting edges to remove material; coolant or cutting fluid may be used to extend life when working metals. Monitor the laser markings to control drilling depth and hole size as required.

Usage recommendations

For best results, match drill speed and feed to the workpiece material, secure thin sheets with clamps or backing to prevent flexing, and use cutting fluid when drilling metals to reduce heat and wear. Replace the bit when cutting edges show visible wear or when hole quality deteriorates.
