Drill bit Irwin 4.2 mm titanium-coated straight shank for metal, MPN 10502583

Irwin 4.2 mm titanium-coated straight shank drill bit for metal is engineered for precise holemaking in steel and other metal alloys. The 4.2 mm cutting diameter provides accurate, repeatable holes while the titanium coating increases surface hardness and reduces wear during continuous drilling. The straight shank is suitable for use in standard hand drills and drill presses, offering compatibility for workshop maintenance, fabrication, and general metalworking tasks where a reliable metal-drilling solution is required.

Advantages

The titanium coating improves wear resistance and extends tool life compared with uncoated bits when used on metal. The 4.2 mm diameter delivers consistent hole size for applications that require dimensional accuracy. The straight shank design ensures secure clamping in standard chucks, and the bit’s geometry promotes efficient chip removal and stable drilling performance in common ferrous and non-ferrous metals.

Suitable for

• Drilling holes in steel sheets and plates
• Maintenance and repair tasks on metal components
• Fabrication and assembly work in workshops
• Use with hand drills and drill presses

Key specifications

• Drill diameter: 4.2 mm
• Shank type: straight shank for standard chucks
• Coating: titanium surface treatment for increased hardness
• Material application: designed for metal and metal alloys
• Typical use: suitable for hand drills and drill presses

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring the straight shank is fully and evenly clamped. Mark the drilling point on the workpiece and, if needed, center-punch to prevent walking. Use appropriate cutting speed and feed for the specific metal being drilled; apply cutting fluid for improved lubrication and cooling when drilling harder steels. Maintain steady pressure and moderate speed, withdrawing occasionally to clear chips and reduce heat buildup.

Usage recommendations

Use cutting lubricant for prolonged bit life when drilling hardened or thicker metal. Replace the bit if wear or chipping reduces drilling accuracy. Always wear appropriate eye and hand protection and secure the workpiece before drilling.
