Drill bit for metal Irwin titanium-coated cylindrical 4.8 mm

Irwin titanium-coated cylindrical drill bit, 4.8 mm diameter, designed for drilling metal. The drill bit is intended for routine metalworking tasks and maintenance where reliable hole quality and wear resistance are required. The titanium coating increases surface hardness and thermal resistance, helping to extend tool life during high-speed drilling in steel and non-ferrous metals. The cylindrical shank fits standard drill chucks and handheld drills used in workshops and on-site service work.

Advantages

The titanium coating improves abrasion resistance and reduces friction, which helps maintain cutting performance for longer compared with uncoated bits. Precision-ground flute geometry and a stable point angle provide consistent chip evacuation and straighter holes. The cylindrical shank offers compatibility with most standard chucks, enabling quick bit changes in handheld and bench drills. Suitable for repeated use in maintenance and general metal fabrication thanks to its balanced combination of hardness and thermal stability.

Suitable for

• Drilling holes in mild and medium-hard steels
• Working with non-ferrous metals such as aluminum and brass
• General workshop and maintenance drilling tasks
• Handheld drills and bench drill press operations

Key specifications

• Diameter: 4.8 mm
• Coating: Titanium (titanium nitride or similar hard coating to increase surface hardness)
• Shank type: Cylindrical shank compatible with standard chucks
• Material suitability: Steel and non-ferrous metals
• Flute geometry: Twist flutes for chip evacuation

How to use

Secure the drill bit firmly in the drill chuck, ensuring the shank is fully seated and tightened. Select an appropriate drilling speed for the material: lower speeds for hard steels and higher speeds for softer non-ferrous metals. Use cutting lubricant when drilling steel to reduce heat buildup and prolong tool life; for aluminum and brass, moderate speeds and controlled feed rates reduce clogging. Apply steady, even pressure without forcing the bit, and periodically withdraw to clear chips if drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Store the drill bit in a dry place and avoid impacts that could damage the cutting edge. Replace the bit when wear or chipping affects hole quality to maintain accurate drilling results.
