Drill bit Irwin 10506623 lip drill bit Ø 2.2 cm, 1 pc

Irwin 10506623 lip drill bit Ø 2.2 cm is a single-piece drill bit designed for creating coarse 22 mm holes in wood and similar materials using a standard drill. The lip-style tip and cutting spurs provide clean hole edges with reduced breakout, while the tapered flute and tri-flute design improve chip ejection and reduce binding during drilling. The bit is heat-treated along its full length to enhance durability for repeated use.

Advantages

The lip drill bit geometry combines cutting spurs and a full screw tip to produce clean holes and easier pull-through. Tapered and tri-flute fluting accelerates chip removal and reduces friction, and the full-length heat treatment increases wear resistance and tool life. Supplied as a single 22 mm bit, it is ready for straightforward use in standard drill chucks without additional adapters.

Suitable for

• Drilling 22 mm diameter holes in soft and hardwood
• Creating clean through-holes for dowels and large fasteners
• General-purpose woodworking and carpentry tasks
• Rapid removal of material when coarse holes are required

Key specifications

• Bit type: lip drill bit with cutting spurs
• Diameter: 2.2 cm (22 mm)
• Overall length: 165 mm
• Flute design: tapered tri-flute for chip ejection
• Tip style: full screw tip for pull-through and centring
• Material suitability: wood and similar timber-based materials
• Finish: full-length heat treatment for increased durability
• Quantity: 1 piece

How to use

Secure the drill bit in a compatible corded or cordless drill chuck and tighten firmly. Mark the hole position on the workpiece and, where appropriate, clamp the workpiece to prevent movement. Start drilling at low speed to allow the full screw tip to engage and centre, then increase speed as the spurs begin to cut. Apply steady, even pressure and allow the tapered tri-flute to evacuate chips; periodically withdraw the bit on deep holes to clear debris and reduce heat build-up. After use, clean wood chips from the flutes and store the bit in a dry place.

Usage recommendations

For best results, use this Irwin 22 mm lip drill bit with a drill capable of variable speed control and sufficient torque for large-diameter wood drilling. Clamp workpieces, drill at moderate speed for hardwood, and clear chips regularly to maintain cutting performance and extend tool life.
