Drill bit Irwin 10502411, HSS high-speed steel, for drilling in metal and general purpose

Irwin 10502411 is a high-speed steel (HSS) drill bit designed for drilling in metal and general-purpose applications. Made from HSS material, this drill bit delivers consistent cutting performance and solid wear resistance suitable for handheld and bench drills. The geometry and heat-treated construction are intended to provide reliable hole-making in a range of ferrous and non-ferrous metals where HSS is the appropriate material choice.

Advantages

The HSS construction ensures a balance of hardness and toughness for repeated metal drilling tasks while resisting softening at elevated drilling temperatures. The bit’s standard tip geometry supports stable centring and consistent chip removal during typical metalworking operations. Compatibility with both portable and stationary drilling equipment makes it a practical choice for workshop and on-site use.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminium and other non-ferrous metals where HSS is appropriate
• General-purpose drilling tasks in small workshops, maintenance and repair operations
• Use with handheld drills and bench or pillar drills for through-holes and pilot holes

Key specifications

• Material: High-speed steel (HSS) for metalworking
• Intended use: Metal drilling and general-purpose applications
• Compatible tools: Handheld drills, bench/pillar drills
• Cutting performance: Designed for consistent cutting and chip evacuation in typical metal drilling conditions
• Heat treatment: Hardened to retain cutting edge at elevated temperatures common in drilling

How to use

Secure the workpiece and select an appropriate drilling speed for the material being machined. Clamp the drill bit firmly in the drill chuck, ensure correct alignment, and apply steady axial pressure while drilling. Use cutting fluid or lubricant when drilling harder metals to reduce heat, improve tool life, and assist chip evacuation. Withdraw the bit occasionally on deeper holes to clear chips and avoid clogging.

Usage recommendations

For best results, match cutting speed and feed to the material—lower speeds for harder steels, higher speeds for aluminium. Use cutting lubricant for stainless steel and other demanding alloys. Inspect the bit for wear or chipping before use and replace if the cutting edge is rounded or damaged to maintain hole quality and safety.
