Drill bit AWTools AW40983 — straight shank, 275 g weight

AWTools AW40983 drill bit is a straight-shank HSS cutting tool with a titanium nitride (TiN) coating and a listed weight of 275 g. Designed for use in compatible power drills and hand drills, this drill bit is intended for general drilling tasks in non-ferrous metals, thin-walled steel sheets and plastics. The TiN coating reduces friction and heat buildup, extending tool life and maintaining cutting performance. Laser-marked engravings on the flutes provide visible size indicators during drilling.

Advantages

The high-speed steel construction offers hardness and wear resistance suitable for repeated use. The titanium nitride coating lowers friction and helps dissipate heat, allowing longer cutting periods and less frequent resharpening. Straight shank design ensures compatibility with standard drill chucks, and laser markings make depth and diameter monitoring straightforward while working. The bit’s geometry enables drilling without the need for pre-drilling in many common materials listed for use.

Suitable for

• Drilling holes in non-ferrous metals such as aluminum and brass
• Working with thin-walled steel sheets
• Drilling through plastics and composite materials
• General repair, assembly and light fabrication tasks

Key specifications

• Material: high-speed steel (HSS)
• Coating: titanium nitride (TiN)
• Shank type: straight shank (suitable for standard chucks)
• Weight: 275 g (listed weight for the product unit)
• Markings: laser-engraved size/depth indicators

How to use

Fit the straight shank securely into the drill chuck and tighten according to the drill manufacturer’s instructions. Select an appropriate drill speed for the material being worked: lower speeds for harder metals, higher speeds for plastics and non-ferrous metals as recommended for HSS bits. Use cutting fluid or lubricant when drilling metals to reduce heat and extend tool life. Apply steady pressure and allow the bit to cut; when working with thin-walled materials support the workpiece to avoid deformation. Monitor the laser markings to control progress and hole depth.

Usage recommendations

Use the appropriate drill speed and coolant for the material, secure the workpiece to prevent movement, and inspect the bit for wear before and after use. Replace or resharpen the bit if cutting performance decreases or if the TiN coating is worn through to maintain consistent hole quality and safe operation.
