Drill bit Irwin titanium-coated for metal, cylindrical shank 4.1 mm, model 10502582

Irwin titanium-coated drill bit for metal with a cylindrical shank and a 4.1 mm diameter. Designed for drilling steel and other metal workpieces, this drill bit combines a wear-resistant titanium coating with a standard cylindrical shank to provide consistent performance in workshop and maintenance environments. The compact diameter is intended for precise small-hole work where control and repeatability are important.

Advantages

The titanium coating reduces friction and surface wear on the cutting edges, which helps maintain sharpness during repeated use and extends overall tool life. The cylindrical shank is compatible with standard drill chucks and provides stable clamping for routine drilling operations. The 4.1 mm diameter offers a balance between rigidity and access for small, accurate holes in metal components.

Suitable for

• Drilling holes in steel, iron, and non-ferrous metal sheets
• Workshop maintenance and repair tasks requiring small-diameter holes
• Precision drilling in metal assemblies and brackets
• Use with hand drills and bench drills that accept cylindrical shanks

Key specifications

• Cutting material: high-speed steel with titanium surface coating
• Shank type: cylindrical
• Drill diameter: 4.1 mm
• Intended material: metal (steel, iron, non-ferrous metals)

How to use

Select a drill chuck that securely accepts a cylindrical shank and clamp the bit firmly to minimize runout. Mark the drilling position and, where applicable, use a center punch to prevent bit wandering on sheet or round stock. Start at a low speed to establish the hole and then increase speed appropriate to the material and drill diameter; apply steady, moderate pressure and use cutting fluid when drilling steel or hardened materials to reduce heat and friction. Periodically retract the bit to clear chips and allow coolant to reach the cutting edges.

Usage recommendations

Use cooling or cutting fluid when drilling steel to extend life of the titanium coating and HSS core. Replace the bit if chipping or significant wear occurs; re-sharpening may be possible for some users but must be performed with appropriate equipment and skill to preserve correct geometry.
