Drill bit Irwin MULTI DRILL BIT 12 x 160 mm for metal and wood

Irwin MULTI DRILL BIT 12 x 160 mm is a multipurpose twist drill designed for drilling both metal and wood. With a 12 mm diameter and 160 mm overall length, this drill bit is suitable for handheld and electric drills with standard chucks. The geometry of the cutting tip and the shaft length provide the reach and stability needed for through-holes and deep drilling in construction, repair and installation tasks.

Advantages

The drill bit combines a design optimized for metal and wood, allowing one tool to be used across different materials without frequent tool changes. Its 160 mm length gives extended reach for deeper holes or working through panels and assemblies. The 12 mm diameter is a common size for bolt holes and anchor fittings, while the shank diameter and conventional twist profile ensure compatibility with most drill chucks. The construction supports accurate centring and consistent chip evacuation during typical drilling operations.

Suitable for

• Drilling through steel, iron and non-ferrous metal sheets and profiles
• Drilling holes in soft and hardwoods, plyboard and chipboard
• Installing bolts, anchors and dowels that require 12 mm holes
• General workshop, construction and maintenance drilling tasks

Key specifications

• Diameter: 12 mm
• Overall length: 160 mm
• Material compatibility: metal and wood
• Shank type: straight shank for standard chucks
• Drill profile: conventional twist drill geometry for chip removal

How to use

Install the drill bit firmly in a compatible drill chuck and tighten according to the drill manufacturer’s instructions. Select a suitable rotational speed for the material: lower speeds for harder metals and higher speeds for wood. Apply moderate, steady feed pressure and allow the bit to cut without excessive force. For metal drilling use cutting fluid or lubricant to reduce heat and extend tool life. Withdraw periodically on deep holes to remove chips and prevent clogging.

Usage recommendations

Wear appropriate eye and hand protection when drilling. Secure workpieces before drilling and ensure the drill is perpendicular to the surface for accurate, clean holes. Match drill speed and lubrication to the material to improve hole quality and prolong bit life.
