Irwin HSS Cylindrical Drill Bit 11.2mm

The Irwin HSS cylindrical drill bit, with a diameter of 11.2mm, is a high-performance tool engineered for precision drilling in metal and various other materials. Constructed from high-speed steel, this drill bit is designed to withstand the rigors of demanding workshop environments while maintaining sharp cutting edges for consistent results. Its standard cylindrical shank design allows for seamless integration with a wide range of power drills and stationary drill presses, ensuring versatility for both professional tradespeople and home DIY enthusiasts.

Advantages

This drill bit offers exceptional durability and heat resistance, which are critical factors when working with hard materials. The high-speed steel composition ensures that the bit retains its structural integrity even during prolonged use, reducing the frequency of replacements. Its precise geometry facilitates clean, accurate holes with minimal burring, thereby improving the quality of your finished projects. The reliable design provides stable performance, allowing for efficient material removal and smooth operation across various metalworking tasks.

Suitable for

• Drilling into steel and iron
• General metalworking applications
• Workshop maintenance and repair tasks
• Creating precise holes for fasteners

When it may not be suitable

This drill bit is specifically optimized for metalworking and may not be the most efficient choice for drilling into masonry, concrete, or extremely hard ceramics. For such materials, specialized carbide-tipped masonry bits are recommended to prevent premature wear or damage to the tool.

Key specifications

• Diameter: 11.2mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Application: Metal drilling

How to use

To achieve the best results, ensure the drill bit is securely tightened in the chuck of your drill or drill press. Mark the center of the hole to be drilled using a center punch to prevent the bit from wandering during the initial contact. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the material being worked on. It is advisable to use a suitable cutting oil or lubricant to reduce friction and heat buildup, which helps extend the lifespan of the drill bit and improves the surface finish of the hole.

What to consider before purchase

• Verify that your drill chuck capacity supports an 11.2mm shank diameter.
• Ensure the material you intend to drill is compatible with high-speed steel bits.
• Consider the depth of the hole required for your specific project.

Usage recommendations

Always wear appropriate eye protection when operating power tools. Regularly inspect the drill bit for signs of wear or dullness and replace it if necessary to maintain drilling efficiency and safety.
