Drill Bit Irwin Multi 14 x 160 mm for Wood and Metal

Irwin Multi 14 x 160 mm drill bit is a long-shank twist bit engineered for through-drilling in both wood and metal. With a 14 mm diameter and 160 mm overall length, this bit provides extended reach for drilling deep holes in structural timber, metal sheets and components. The bit features a centering tip for accurate starts and a spiral flute designed to evacuate chips efficiently, making it compatible with both cordless and corded drills for construction, installation and repair tasks.

Advantages

The centering tip ensures precise positioning and reduces walking at drill startup, improving hole accuracy. The long shank and extended length enable drilling through thicker workpieces or reaching recessed drilling points without extensions. Spiral flutes promote rapid chip removal to maintain cutting efficiency when working with wood and thinner metal sections. The bit's geometry balances cutting performance and durability for mixed-material use.

Suitable for

• Through-drilling holes in timber beams and joists
• Drilling holes in steel sheets and metal profiles
• Installation of bolts, dowels and long fasteners
• Reach work in recessed or hard-to-access locations
• General construction, maintenance and repair jobs

Key specifications

• Diameter: 14 mm
• Overall length: 160 mm
• Suitable materials: wood and metal
• Tip type: centering tip for accurate starts
• Shank type: long-shank twist design for extended reach
• Flute type: spiral flute for efficient chip evacuation
• Compatible drives: standard drill chucks on corded and cordless drills

How to use

Secure the bit in the drill chuck and tighten firmly before use. Mark the drilling position and, where necessary, start at low speed to allow the centering tip to locate without walking. Apply steady, even pressure and increase speed as the bit becomes engaged in the material. Withdraw the bit periodically on deep holes to clear chips and reduce heat buildup. For metal drilling, use appropriate cutting fluid or lower speeds to prolong bit life; for wood, moderate speed and consistent feed deliver clean holes.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves and hearing protection) when drilling. Match drill speed and feed to the material: slower speeds and cutting lubricant for metals, moderate-to-high speeds for softwoods. Inspect the bit before use for signs of wear or damage and replace if cutting performance deteriorates.
