Drill bit AWTools AW41402 — high-speed steel twist bit for metal and wood

AWTools AW41402 is a high-speed steel (HSS) twist drill bit designed for routine drilling in metal and wood. The bit has a standard straight shank for secure mounting in handheld and benchtop drills. Built for general-purpose workshop and construction use, this HSS twist bit provides consistent cutting performance and a balance of hardness and toughness appropriate for steel, cast iron, non-ferrous metals and common wood types.

Advantages

The HSS material offers elevated heat resistance compared with carbon steel, which helps maintain edge sharpness during higher-speed drilling. The twist-flute geometry efficiently evacuates chips from the hole, reducing clogging and promoting smoother drilling. The straight shank ensures compatibility with common drill chucks, enabling stable mounting and reliable concentricity. Overall construction focuses on durability and versatility across multiple materials.

Suitable for

• Drilling through mild and medium steel
• Drilling holes in cast iron and non-ferrous metals (aluminium, brass)
• General woodworking tasks and drilling in soft and hardwood
• Routine workshop and construction site applications

Key specifications

• Material: high-speed steel (HSS)
• Tip geometry: twist drill profile for general-purpose cutting
• Shank type: straight shank for standard drill chucks
• Intended use: metal and wood drilling
• Compatibility: handheld and benchtop drills

How to use

Select the appropriate drilling speed for the material being worked: lower speeds for harder metals and higher speeds for softer metals and wood. Secure the workpiece with clamps or a vise to prevent movement, and mount the straight shank of the bit firmly in the drill chuck. Use light, steady feed pressure to allow the bit to cut and evacuate chips; withdraw occasionally when drilling deep holes to clear swarf. For metal drilling, use cutting fluid or coolant as needed to reduce heat and extend bit life.

Usage recommendations

For best results, match drill speed and feed to the material: reduce speed and apply cutting fluid when drilling hard steels; increase speed moderately for wood. Keep the bit sharp and replace when worn or chipped to maintain hole quality and safety. Store the bit dry to avoid corrosion and inspect the shank for secure clamping before use.
