## Long description

Irwin lip drill bit 10506624 is a single 25 mm diameter lip drill bit designed for general drilling tasks in wood. The bit features cutting spurs for clean hole edges, a full screw tip to assist pull-through and centring, and a tapered tri-flute design to reduce binding and speed chip ejection. The tool is supplied as one piece and has full-length heat treatment for improved durability, making it suitable for repair, construction and installation tasks that require a 25 mm cutting tool.
Advantages
The cutting spurs create neat hole perimeters with minimal breakout, while the full screw tip helps start and pull the bit through the workpiece with less effort. The tapered flute and tri-flute geometry reduce clogging and improve chip evacuation for faster, more efficient drilling. Full-length heat treatment enhances wear resistance and extends tool life under regular use. Overall, the design balances clean finish, ease of use and service life for woodworking applications.
Suitable for (tasks / use cases)

How to use
Secure the Irwin 25 mm lip drill bit in a compatible drill chuck, ensuring the bit is properly seated and tightened. Mark the hole position on the workpiece and if necessary use a pilot mark to guide the screw tip. Begin drilling at a moderate speed to allow the screw tip to pull the bit into the material, then maintain consistent pressure and speed appropriate for the wood type. Clear chips periodically if drilling deep holes to prevent clogging and overheating. After use, clean the bit and store it dry to preserve the heat-treated surface.
Usage recommendations
Use the bit primarily for wood and wood-based panels; avoid using it on metals, masonry or ceramic materials. For best results, match drill speed and feed rate to the wood species: lower speeds for hardwoods and higher speeds for softwoods. Wear appropriate eye and hearing protection and ensure the workpiece is securely clamped before drilling.
