Drill bit for metal Irwin titanium cylindrical 4.5 mm

Cylindrical Irwin drill bit for metal with a 4.5 mm cutting diameter and titanium coating, made for drilling steel and other ferrous and non-ferrous metals. The bit is intended for use in handheld electric drills and drill presses. Titanium coating increases surface hardness and wear resistance, providing longer tool life and consistent cutting performance in workshop, construction, and repair environments.

Advantages

The titanium coating delivers improved surface hardness and reduced friction, which helps the drill bit maintain sharpness longer than uncoated bits. Its cylindrical shank fits standard chucks without additional adapters, enabling quick bit changes and steady clamping. The design provides reliable chip evacuation and stable drilling at typical speeds for metalworking, reducing the risk of overheating during normal use.

Suitable for

• Drilling holes in mild and medium-hard steels
• Work on stainless-steel thin sheets and aluminium
• General repair and maintenance tasks in workshops and on construction sites
• Use with handheld electric drills and bench drill presses

Key specifications

• Cutting diameter: 4.5 mm
• Tip and flute geometry: standard twist drill profile suitable for metal
• Coating: titanium (titanium nitride-style) for increased hardness and wear resistance
• Shank type: cylindrical shank for standard drill chucks
• Intended materials: ferrous and non-ferrous metals

How to use

Mark the drilling position and secure the workpiece to prevent movement. Select an appropriate drilling speed for metal (moderate RPM for steels, higher for softer metals) and use cutting lubricant or coolant when drilling harder steels to reduce heat and prolong bit life. Start drilling with light pressure to establish the pilot point, then apply steady, moderate feed until the hole is complete. Withdraw the bit periodically on deeper holes to clear chips and allow cooling.

Usage recommendations

For best results, use cutting fluid when drilling thicker or harder metals, clamp workpieces securely, and avoid excessive feed force or speed that can overheat and blunt the titanium coating. Inspect the bit for wear before use and replace when cutting efficiency decreases.
