Drill bit AWTools AW42780 — metal/wood drilling bit, model AW42780

AWTools AW42780 is a single twist drill designed for general-purpose drilling in metal and wood. Constructed from alloy steel with a carbide tip and two cutting edges, this drill bit provides a balance of hardness and toughness for workshop and maintenance tasks. The double spiral flute improves chip evacuation and reduces heat buildup during continuous use. With a 130° point angle, the bit offers accurate centering and smooth penetration in a range of materials.

Advantages

The alloy steel body with a carbide tip enhances durability and maintains cutting performance over repeated use. Two cutting edges deliver precise and clean holes while the double spiral flute ensures efficient removal of chips and debris, preventing clogging and overheating. The 130° point angle gives improved centering and reduces walking at the drill start, making the bit suitable for steady drilling operations.

Suitable for

• Drilling holes in metal components and structural parts
• Woodworking tasks requiring accurate through-holes or pilot holes
• Workshop maintenance and repair applications
• Use with handheld drills and drill presses for general-purpose drilling

Key specifications

• Material: alloy steel with carbide tip
• Cutting design: two cutting edges
• Flute type: double spiral flute for enhanced chip evacuation
• Point angle: 130° for improved centering
• Intended materials: metal and wood
• Compatibility: suitable for handheld drills and drill presses

How to use

Select a drill speed appropriate for the material being worked: moderate to high speeds for wood and lower speeds with steady feed for metal. Secure the workpiece and, where possible, use a center punch for metals to prevent wandering. Align the bit perpendicular to the surface, apply steady pressure, and allow the drill to do the cutting; avoid excessive force that can cause bit wear or breakage. Withdraw periodically when drilling deep holes to clear chips and allow cooling.

Usage recommendations

For prolonged bit life when drilling metal, use cutting fluid or lubricant and maintain lower rotational speeds with steady feed. When drilling wood, ensure clean chip removal by using appropriate speeds and backing the workpiece to prevent splintering. Inspect the carbide tip for wear and replace the bit if cutting performance declines significantly.
