Buying advice

When selecting a counterbore, consider the screw size and material you'll be working with. HSS is versatile for most metals, while carbide excels in abrasive or non-ferrous materials. Sets offer better value if you need multiple sizes, but individual tools provide higher precision. Always check that the product is listed under Industrial & Scientific > Cutting Tools to ensure genuine counterbore suitability.
