Drill bit Irwin Lip drill bit 8 mm 1 pc

The Irwin Lip drill bit 8 mm is a single-piece lip (twist) drill designed for general drilling tasks in materials appropriate for the bit's material. The 8 mm diameter and centre point tip provide precise, easy starts, while the fully hardened body improves wear resistance for extended use. Wide flutes help evacuate chips quickly and the spurred cutting head reduces splintering for smoother, cleaner holes. This single drill bit is suitable as a replacement in drill sets, for on-site repairs and for everyday DIY and professional applications.

Advantages

The centre point tip ensures accurate positioning and reduces walking at drill start. A fully hardened shaft increases durability and wear resistance across repeated use. The spurred cutting head is engineered to produce clean hole edges and limit material tear-out on softer surfaces. Wide flutes facilitate rapid chip removal, improving cutting efficiency and reducing heat buildup during sustained drilling.

Suitable for

• Drilling holes in metal where the bit material is appropriate
• Drilling in wood with reduced splintering thanks to the spurred head
• Drilling in plastics when recommended for the bit material
• Replacement of worn bits in drill sets and toolkits
• On-site repair and maintenance tasks requiring precise, clean holes

How to use

Secure the drill bit in the chuck of a compatible drill, ensuring tight, concentric clamping. Mark the drilling position and, if needed, use a pilot mark or centre punch to align the centre point tip. Start drilling at low speed to establish the hole, then increase speed and moderate feed pressure appropriate to the work material. Use cutting fluid when drilling metals to reduce heat and prolong bit life. Remove the bit periodically to clear chips when drilling deep holes.

Usage recommendations

Use the Irwin Lip 8 mm drill bit with appropriate speeds and lubrication for the material being drilled. For best results in wood and plastics, secure the workpiece to prevent movement and back the material where possible to avoid exit splintering. Replace the bit when signs of wear or chipping appear to maintain hole quality.
