How to use

Mount the countersink in a compatible drill or driver with the appropriate shank or adapter. Align the tip with the intended screw position, apply steady axial pressure, and run the drill at a speed suitable for the wood species to achieve a clean 20 mm countersink. Withdraw the tool periodically to clear chips and avoid overheating. For repeat operations, maintain consistent positioning and feed to ensure uniform countersink depth and edge finish across all workpieces.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Test the countersink on a scrap piece of the same material to confirm depth and finish before working on the final parts. Keep a supply of replacements from the pack to maintain workflow in production settings; store the tools dry to prevent corrosion if metal components are present.
