## Long description

The Irwin HSS metal drill bit, measuring 10.4 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 provides the necessary hardness and heat resistance required for consistent performance in demanding drilling tasks. Its design facilitates efficient chip removal, ensuring that the cutting edge remains clear and effective during operation. The cylindrical shank allows for secure mounting in standard drill chucks, making it a versatile addition to any professional workshop or home tool collection.
Advantages
This drill bit stands out due to its robust construction and high-speed steel composition, which significantly extends its service life even when working with tougher materials. The geometry of the bit is optimized for stability, reducing the likelihood of wandering during the initial contact with the metal surface. By maintaining a sharp cutting edge, it delivers clean and accurate holes with minimal burring, which reduces the need for secondary finishing work. Its compatibility with standard power tools ensures that users can achieve professional-grade results without the need for specialized equipment.
Suitable for
Drilling holes in mild steel and iron
General metalworking and fabrication tasks
DIY home repair and maintenance projects
Creating pilot holes for larger fasteners
When it may not be suitable
This drill bit is not intended for use on hardened steel, stainless steel, or masonry surfaces, as these materials require specialized cobalt or carbide-tipped bits to prevent premature wear or breakage. It is also not suitable for use in impact drivers or hammer drills, as the high-impact force can damage the bit structure.
Key specifications
Material: High-speed steel (HSS)
Diameter: 10.4 mm
Working length: 87 mm
Total length: 133 mm
Shank type: Cylindrical
How to use
To achieve the best results, ensure the workpiece is securely clamped to prevent movement during the drilling process. Mark the center point of the hole clearly before starting. Begin drilling at a low speed to establish a starting point, then gradually increase the speed while maintaining steady, moderate pressure. It is highly recommended to use a suitable cutting oil or lubricant to reduce friction and heat buildup, which helps preserve the sharpness of the bit and improves the quality of the hole.
What to consider before purchase
Verify the maximum chuck capacity of your drill to ensure it accommodates a 10.4 mm shank.
Check the material compatibility to ensure it meets your specific project requirements.
Consider purchasing a set of bits if you require multiple sizes for your work.
Usage recommendations: Always wear appropriate eye protection when drilling metal to guard against flying chips. Regularly inspect the bit for signs of dulling or damage and replace it if necessary to maintain safety and efficiency.
