Drill bit Irwin Lip drill bit 1.3 cm diameter, 1 pc

Irwin Lip drill bit 1.3 cm diameter, 1 pc is a single-piece lip bit designed for standard drilling tasks in wood, plastics and some non-hardened metals when used with compatible hand or power drills. The bit features a centre point for accurate starts, a spurred cutting head to reduce splintering and wide flutes to evacuate chips quickly. The fully hardened body increases wear resistance for routine repair, carpentry and general construction work.

Advantages

The centre point ensures precise positioning and reduces walking at contact. Fully hardened construction improves durability and extends service life under normal working conditions. The spurred cutting head produces cleaner, more defined edges in wood and reduces tear-out, while wide flutes allow fast and continuous removal of chips to maintain stable drilling performance.

Suitable for

• Drilling round holes in timber for joinery and carpentry
• General repair and construction drilling tasks
• Working with plastics and some non-hardened metals where a lip bit is suitable
• Use with compatible handheld drills and drill motors

Key specifications

• Type: Lip drill bit
• Drill bit diameter: 1.3 cm
• Overall length: 151 mm
• Material compatibility: Wood, plastics, some non-hardened metals
• Shank type: Cylindrical shank
• Quantity: 1 piece
• Features: Centre point, spurred cutting head, fully hardened body, wide flutes

How to use

Secure the drill bit in a compatible chuck with the cylindrical shank fully seated. Mark the drilling point and, if needed, clamp the workpiece to prevent movement. Start drilling at low speed to engage the centre point, then increase speed suitable for the material. Apply steady, controlled feed pressure and allow the wide flutes to clear chips; withdraw occasionally on deep holes to remove debris. For best results in wood, use the spurred tip to maintain clean edges and reduce splintering.

Usage recommendations

Use appropriate personal protective equipment and match drill speed to the material. Avoid excessive side load and overheating; let the bit cool between prolonged runs. For non-hardened metals, use cutting fluid as required and verify compatibility before use.
