Product information

Description

The Irwin HSS cylindrical drill bit with a 7.8mm diameter is a high-performance tool engineered for precision drilling in a variety of metal surfaces. Constructed from high-speed steel, this drill bit is designed to withstand the rigors of demanding drilling tasks while maintaining structural integrity and sharpness. Its geometry facilitates efficient chip removal, which helps prevent overheating and ensures a smooth, clean finish in both ferrous and non-ferrous metals.

Advantages

This drill bit offers exceptional durability and heat resistance due to its high-speed steel composition, allowing for consistent performance over extended periods of use. The precision-ground tip ensures accurate centering and reduces walking on the workpiece, which is essential for achieving clean, professional-grade holes. Its robust design minimizes the risk of breakage under pressure, providing reliability for both intensive professional projects and home improvement tasks.

Suitable for

  • Drilling into mild steel and carbon steel
  • Working with non-ferrous metals like aluminum and copper
  • General metal fabrication and repair tasks
  • DIY metalworking projects

When it may not be suitable

This drill bit is not intended for drilling into hardened steel, stainless steel alloys that require specialized cobalt bits, or masonry materials such as concrete and stone. Using it on these materials may cause premature dulling or damage to the cutting edge.

Key specifications

  • Diameter: 7.8mm
  • Material: High-speed steel (HSS)
  • Shank type: Cylindrical
  • Application: Metal drilling

How to use

To use the Irwin HSS drill bit, ensure it is securely fastened in the chuck of your power drill or drill press. Mark the center point of the hole to be drilled using a center punch to prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent drilling speed appropriate for the metal being worked on. It is recommended to use a cutting fluid or oil to lubricate the bit and cool the workpiece, which significantly extends the life of the tool and improves the quality of the hole.

What to consider before purchase

  • Verify that your drill chuck is compatible with a 7.8mm cylindrical shank
  • Ensure the material you are drilling is compatible with standard HSS tools
  • Consider purchasing a set of bits if you require multiple sizes for your project

Usage recommendations

Always wear appropriate eye protection when drilling metal. Periodically clear metal shavings from the hole to prevent clogging and overheating, and allow the bit to cool down if it becomes excessively hot during operation.
