Irwin HSS PRO Metal Drill Bit 9.7 x 87/133 mm

The Irwin HSS PRO metal drill bit, measuring 9.7 x 87/133 mm, is a high-performance tool engineered for precision drilling in various metal surfaces. Constructed from high-speed steel, this drill bit is designed to withstand the rigors of demanding metalworking tasks while maintaining structural integrity and sharpness over extended periods of use. Its geometry facilitates efficient chip removal, which helps prevent overheating and ensures consistent drilling performance in steel and alloy materials.

Advantages

The primary benefit of this drill bit is its robust high-speed steel construction, which provides excellent heat resistance and durability during intensive drilling operations. The design allows for clean, accurate holes, reducing the need for secondary finishing work. Furthermore, the optimized flute geometry ensures that metal shavings are cleared rapidly from the hole, which significantly improves drilling speed and extends the overall lifespan of the tool.

Suitable for

• Drilling into mild steel and carbon steel
• Working with various metal alloys
• Professional metal fabrication projects
• DIY home improvement and repair tasks

When it may not be suitable

This drill bit is not intended for drilling into hardened steel, stainless steel, or masonry materials, as these require specialized cobalt or carbide-tipped bits. Using this tool on materials harder than its design specifications may lead to premature dulling or breakage.

Key specifications

• Diameter: 9.7 mm
• Working length: 87 mm
• Total length: 133 mm
• Material: High-speed steel (HSS)
• Application: Metal drilling

How to use

To achieve the best results, secure the workpiece firmly in a vice or clamp to prevent movement during the drilling process. Mark the exact center point of the hole using a center punch to ensure the drill bit does not wander upon contact. Start the drill at a moderate speed and apply steady, consistent pressure. It is recommended to use a suitable cutting oil to lubricate the bit and cool the contact area, which helps maintain the sharpness of the cutting edges and improves the quality of the hole.

What to consider before purchase

• Verify the chuck capacity of your drill to ensure it accommodates a 9.7 mm shank
• Ensure the material being drilled is compatible with standard high-speed steel
• Consider purchasing a set if you require multiple sizes for your project

Usage recommendations

Always wear appropriate eye protection and safety gear when operating power tools. Periodically inspect the drill bit for signs of wear or damage and replace it if the cutting edges become dull to ensure safe and efficient operation.
