Drill bit for metal Irwin titanium-coated cylindrical 3.2 mm 10502578

Irwin cylindrical drill bit with a titanium coating, diameter 3.2 mm, is designed for drilling steel and other metals where a precise, small-diameter hole is required. The titanium finish increases surface hardness and improves wear resistance compared with untreated bits, extending tool life under frequent use. The cylindrical shank fits standard chucks on handheld drills and drill presses, making this bit suitable for both field service and shop applications.

Advantages

The titanium coating provides higher surface hardness and better resistance to abrasion, reducing flank wear and preserving sharpness for longer periods. The 3.2 mm diameter delivers consistent hole size for accurate fastening and alignment tasks. Its cylindrical shank ensures compatibility with common drill chucks and allows secure clamping for stable drilling. The geometry is optimized for cutting metal, helping maintain straightness and reduce walking at the start of a hole.

Suitable for

• Drilling steel and ferrous metals
• Working with non-ferrous metals such as aluminum and brass
• Maintenance and repair tasks requiring precise 3.2 mm holes
• Use with handheld drills and drill presses in workshops and on-site

Key specifications

• Diameter: 3.2 mm
• Shank type: cylindrical (straight)
• Coating: titanium (titanium nitride or equivalent finish to increase hardness and wear resistance)
• Primary application: drilling metals (steel, non-ferrous metals)
• Compatible tools: handheld drills, drill presses with standard chucks

How to use

Mark the drilling point and secure the workpiece to prevent movement. Use a center punch if necessary to prevent the bit from walking at startup. Install the drill bit in the chuck and tighten securely. For metal drilling, use appropriate cutting speed and moderate feed pressure; apply cutting fluid or lubricant to reduce heat and extend bit life. Withdraw the bit occasionally to clear chips, and let the bit cool before re-lubricating if performing multiple holes in succession.

Usage recommendations

For best results, select drill speeds suited to the metal being cut (lower speeds for harder steels, higher speeds for softer non-ferrous metals) and use light cutting fluid. Avoid excessive lateral force to maintain bit straightness and prolong service life.
