Irwin 10502792 Lip and Spur Wood Drill Bit 3 mm

The Irwin 3 mm lip and spur wood drill bit is a precision-engineered tool designed for clean and accurate drilling in various types of wood. Featuring a specialized geometry, this drill bit ensures that every hole is perfectly positioned and finished with minimal splintering. Its robust construction and hardened body make it a reliable choice for both professional woodworkers and DIY enthusiasts who require consistent results in their woodworking projects.

Advantages

This drill bit stands out due to its sharp center point, which allows for precise positioning before drilling begins, preventing the bit from wandering across the surface. The integrated spurs on the cutting head are specifically designed to score the wood fibers, resulting in exceptionally clean hole edges. Furthermore, the wide flutes facilitate a rapid and continuous flow of wood chips, preventing clogging and ensuring efficient material removal during operation.

Suitable for

• Furniture assembly and repair
• Cabinet making and joinery
• Precision drilling for dowels
• General woodworking projects

This drill bit is not suitable for drilling into hard materials such as metal, masonry, or concrete. Attempting to use it on these surfaces will cause immediate damage to the cutting edges and the center point, rendering the tool ineffective.

Key specifications

• Diameter: 3 mm
• Type: Lip and spur drill bit
• Shank: Cylindrical
• Total length: 61 mm
• Material compatibility: Wood

How to use

To achieve the best results, ensure your workpiece is securely clamped to a stable surface to prevent movement. Align the center point of the drill bit with your marked hole location and apply steady, moderate pressure while maintaining a perpendicular angle to the wood surface. Use a consistent drill speed to allow the wide flutes to clear the debris effectively. Avoid excessive force, as this can lead to overheating or splintering of the wood fibers.

What to consider before purchase

• Verify that your drill chuck is compatible with a cylindrical shank.
• Ensure the 3 mm diameter meets the specific requirements of your fasteners or dowels.
• Check that the material you are drilling is wood, as this bit is not designed for other substrates.

Usage recommendations

For optimal longevity and performance, keep the drill bit clean and store it in a dry place. Avoid dropping the bit on hard surfaces to protect the precision-ground center point and spurs from chipping.
