Drill bit for metal Irwin titanium-coated cylindrical 5.5 mm

Irwin titanium-coated cylindrical drill bit, 5.5 mm diameter, engineered for drilling metal surfaces with consistent performance. The 5.5 mm cutting diameter delivers precise through-holes and pilot holes in a range of ferrous and non-ferrous metals. A cylindrical shank fits standard chucks and allows quick mounting in hand drills and drill presses. The titanium coating reduces friction, improves heat resistance, and extends tool life during repetitive metalworking tasks.

Advantages

The titanium coating on this 5.5 mm metal drill bit lowers cutting friction and enhances wear resistance, resulting in longer service life compared with uncoated bits. The cylindrical shank offers compatibility with most standard chucks and provides stable rotation for accurate hole positioning. Its geometry is optimized for efficient chip evacuation and reduced heat build-up during continuous drilling in sheet metal and thicker workpieces.

Suitable for

• Drilling precise 5.5 mm holes in steel, aluminium, and other metals
• Workshop and maintenance tasks requiring repeatable hole sizes
• Use with handheld electric drills and drill presses

Key specifications

• Cutting diameter: 5.5 mm
• Shank type: cylindrical (round) shank for standard chucks
• Coating: titanium for reduced friction and improved wear resistance
• Intended material: metal (ferrous and non-ferrous)
• Typical applications: through-holes, pilot holes, general metal drilling

How to use

Secure the drill bit firmly in the chuck of a handheld drill or drill press, ensuring proper alignment. Select an appropriate drilling speed for the specific metal—lower speeds for harder steels, higher speeds for aluminium—apply steady pressure, and allow the bit to cut without forcing. Use cutting fluid or coolant where appropriate to reduce heat and extend bit life. Clear chips regularly to prevent clogging and to maintain drilling accuracy.

Usage recommendations

For best results, start with a center punch to prevent wandering, choose drilling speeds and feed rates suitable for the metal, and use cutting lubricant during longer or deeper holes. Replace the bit when cutting performance declines or when wear visibly affects hole quality.
