Metal drill bit HSS Titanium, Irwin, 12.0 mm

The Irwin Metal drill bit HSS Titanium 12.0 mm is a high-speed steel cutting tool with a titanium coating, engineered for drilling accurate holes in a range of ferrous and non-ferrous metals. Designed for use in both hand drills and drill presses, the 12.0 mm diameter provides a balance between chip clearance and hole tolerance for common workshop and maintenance tasks. The titanium coating reduces friction and improves wear resistance compared with uncoated HSS bits, extending useful life under typical metalworking conditions.

Advantages

The titanium-coated HSS construction increases surface hardness and lowers heat transfer during drilling, which helps maintain cutting edge sharpness and reduces galling when working with stainless steel and other tougher alloys. The 12.0 mm flute geometry aids chip evacuation and stable drilling, while the general-purpose design makes the bit compatible with a wide range of steels, aluminium, brass and similar materials. Suitable for both portable and stationary drilling equipment, the bit provides consistent hole quality when used with correct speeds and feed rates.

Suitable for

• Drilling holes in mild and hardened steels
• Drilling aluminium, brass and other non-ferrous metals
• Workshop maintenance and repair tasks
• Use with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS) with titanium coating
• Diameter: 12.0 mm
• Suitable materials: ferrous and non-ferrous metals
• Point geometry: standard twist drill (optimized for general-metal drilling)
• Compatibility: handheld electric drills and bench drill presses

How to use

Secure the workpiece and select an appropriate cutting speed for the material—lower speeds for stainless and hardened steels, higher speeds for aluminium. Clamp the 12.0 mm Irwin HSS Titanium bit firmly in the drill chuck, ensure correct alignment, and apply steady, moderate pressure during drilling. Use cutting fluid or lubricant when drilling tougher alloys to reduce heat and prolong tool life. Periodically clear chips from the hole to prevent clogging and overheating.

Usage recommendations

For best performance, match drill speed and feed to the workpiece material, use cutting lubricant on hard or heat-sensitive metals, and replace the bit when wear or rounding of the cutting lips becomes apparent to maintain hole accuracy and safety.
