How to use
To use the Irwin HSS drill bit, ensure it is securely tightened in the chuck of your drill or drill press. Mark the center 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 suitable for the material being worked on. It is recommended to use a cutting fluid or lubricant when drilling into metal to reduce friction, extend the life of the bit, and improve the quality of the hole.
What to consider before purchase
Verify that your drill chuck supports an 8.4mm cylindrical shank
Ensure the material you intend to drill is compatible with HSS bits
Consider using a pilot hole for thicker metal sheets
Usage recommendations
Always wear appropriate eye protection when drilling. Regularly inspect the bit for signs of wear or dulling to maintain drilling efficiency and safety.
