Irwin HSS Cylindrical Drill Bit 4.8mm

The Irwin HSS cylindrical drill bit, with a diameter of 4.8mm, is a high-performance tool engineered for precision drilling in metal surfaces. Manufactured from high-speed steel, this drill bit offers excellent heat resistance and structural integrity, ensuring consistent performance during demanding drilling tasks. Its cylindrical shank design is compatible with standard drill chucks, making it a versatile addition to any professional or home workshop tool collection.

Advantages

This drill bit stands out due to its robust high-speed steel construction, which provides superior durability and resistance to wear even when working with harder materials. The precision-ground geometry ensures clean and accurate holes, reducing the need for secondary finishing. Its design promotes efficient chip removal, which prevents overheating and extends the overall lifespan of the tool, allowing for reliable and repeatable results across various metalworking applications.

Suitable for

• Drilling precise 4.8mm holes in steel and iron
• General metal fabrication and repair work
• Professional workshop maintenance
• DIY metalworking and hobbyist projects

When it may not be suitable

This drill bit is specifically optimized for metal drilling and may not perform optimally when used on masonry, concrete, or extremely hard tempered alloys. It is not intended for use in hammer drill modes, as the impact force can damage the cutting edge.

Key specifications

• Diameter: 4.8mm
• 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 will prevent the bit from wandering during the initial contact. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is recommended to use a suitable cutting oil to reduce friction and heat, which will significantly improve the quality of the hole and preserve the sharpness of the cutting edges.

What to consider before purchase

• Verify that your drill chuck supports a 4.8mm cylindrical shank
• Ensure the material hardness is compatible with standard HSS tools
• Consider purchasing a set if multiple hole sizes are required for your project

Usage recommendations

Always wear appropriate eye protection when drilling metal to prevent injury from flying chips. Regularly inspect the drill bit for signs of dulling or damage and replace it if necessary to maintain drilling efficiency and safety.
