Irwin HSS Metal Drill Bit, 17.5mm, Cylindrical Shank

The Irwin HSS metal drill bit with a 17.5mm diameter is a high-performance tool engineered for precision drilling in a variety of metal surfaces. Constructed from high-speed steel, this drill bit provides the necessary hardness and heat resistance required for demanding metalworking tasks. Its standard cylindrical shank design ensures compatibility with a wide range of drill chucks, making it a versatile addition to any workshop or tool kit.

Advantages

This drill bit stands out due to its robust high-speed steel composition, which maintains sharpness and structural integrity even during prolonged use. The precision-ground geometry allows for efficient chip removal and accurate hole placement, reducing the risk of wandering during the initial contact with the material. Its durable design minimizes the frequency of replacements, offering reliable performance for both professional tradespeople and home improvement enthusiasts.

Suitable for

• Drilling into mild steel and iron
• Working with various metal alloys
• General metal fabrication and repair tasks
• Professional workshop applications and DIY projects

When it may not be suitable

This drill bit is specifically optimized for metal applications and may not perform efficiently on masonry, concrete, or extremely hard materials like hardened tool steel. It is also not intended for use with materials that require specialized carbide-tipped bits for optimal results.

Key specifications

• Diameter: 17.5mm
• 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 fastened in the chuck of your power drill or drill press. Mark the center point of the hole to be drilled and use a center punch to create a small indentation, which helps guide the bit. Apply steady, moderate pressure while maintaining a consistent drilling speed suitable for the material thickness. It is recommended to use a cutting fluid or lubricant to reduce friction and heat buildup, which helps extend the lifespan of the drill bit and ensures a cleaner finish.

What to consider before purchase

• Verify that your drill chuck capacity supports a 17.5mm shank diameter
• Ensure the material being drilled is compatible with high-speed steel bits
• Consider the need for a drill press for larger diameter holes to maintain stability

Usage recommendations

Always wear appropriate eye protection and safety gear when operating drilling equipment. Periodically inspect the bit for signs of wear or dullness and sharpen or replace it as necessary to maintain drilling efficiency and safety.
