Drill bit AWTools AW41381 — high-speed steel twist drill, size not specified

AWTools AW41381 is a high-speed steel (HSS) twist drill designed for general-purpose drilling tasks. Produced by AWTools, this conventional straight-shank drill bit is suitable for handheld and bench drills. The listing does not specify diameter or length; therefore this description focuses on typical HSS twist drill properties and common workshop uses. The AW41381 performs clean cutting in a range of materials when matched to the correct size and drilling speed, and is intended for drilling, hole preparation and routine workshop repairs.

Advantages

The AWTools AW41381 combines the wear resistance and hardness of high-speed steel with a conventional twist point geometry that offers reliable centring and chip evacuation in common materials. Its straightforward design makes it compatible with standard drill chucks and simple to use for both occasional and repeated drilling operations. Because HSS is a general-purpose material, the bit maintains cutting performance at elevated temperatures better than carbon-steel equivalents and is suitable for a wide variety of tasks when the correct diameter is selected.

Suitable for

• Drilling holes in soft steels and non-ferrous metals when appropriate cutting speed is used
• General-purpose wood drilling and carpentry work
• Plastic and composite materials with care to avoid melting or cracking
• Workshop repair, maintenance and prototype assembly

Key specifications

• Material: high-speed steel (HSS)
• Drill type: twist drill with conventional point geometry
• Shank style: straight shank for standard drill chucks
• Compatibility: handheld and bench drilling machines
• Typical suitability: metal, wood, plastic (dependent on diameter and drilling parameters)

How to use

Select a drill diameter and cutting speed appropriate for the material to be drilled. Secure the workpiece and use a centre punch for accurate starting position when drilling metal. Fit the AWTools AW41381 into a compatible chuck and tighten securely. Start drilling at a moderate speed, increase feed steadily, and use cutting lubricant when drilling ferrous metals to extend tool life. For wood and plastics use lower speeds for large diameters and moderate feed to prevent chipping or melting. Clear chips periodically to maintain efficient cutting.

Usage recommendations

Match drilling speed, feed and lubrication to the material: use cutting oil for steel, moderate speeds for non-ferrous metals, and lower speeds for plastics. Inspect the bit before use and replace if worn or damaged. Store in a dry place to prevent corrosion.
