Drill bit Irwin Lip drill bit 10 mm 1 pc

The Irwin Lip drill bit 10 mm is a single-piece lip-type twist drill designed for general-purpose drilling with standard drills. It features a centre point for accurate positioning and easy start-up, a fully hardened body to improve wear resistance, a spurred cutting head to reduce splintering and create clean hole edges, and wide flutes that speed chip evacuation. Supplied as one 10 mm drill bit, it is suitable for repair, construction and DIY tasks where a precise 10 mm hole is required.

Advantages

This 10 mm Irwin Lip drill bit offers reliable starting accuracy thanks to its centre point and delivers longer service life due to a fully hardened body. The spurred cutting head limits material tear-out for neater finishes, while the wide flutes maintain continuous chip removal to reduce clogging and heating during use. The single-piece design ensures stable cutting action when used with standard hand or power drills.

Suitable for

• General-purpose drilling in wood and soft composite materials
• Repair and maintenance tasks requiring a 10 mm hole
• Construction site work with standard drill machines
• DIY projects such as furniture assembly, mounting and fitting

How to use

Secure the drill bit in the chuck of a standard hand or power drill and tighten firmly. Position the centre point on the marked drilling spot and start drilling at low speed to establish the initial hole, then increase speed as appropriate for the material. Use steady pressure and allow the wide flutes to carry chips away; pause periodically for deep holes to clear debris. Ensure the workpiece is clamped or otherwise secured before drilling.

Usage recommendations

For best results, match drilling speed and feed to the material: lower speeds for harder or laminated surfaces and higher speeds for soft wood. Apply cutting lubricant when drilling certain composites or when prolonged drilling causes heat build-up. Inspect the drill bit regularly for wear and replace when the cutting edges become dull to maintain clean holes and reduce the risk of damage to the workpiece.
