How to use

Install the Dedra wood drill bit into a compatible drill chuck and tighten securely. Select an appropriate rotation speed for the wood type—moderate speeds for hardwoods and higher speeds for softwoods—apply steady forward pressure and allow the bit to cut without excessive force. Withdraw the bit periodically for chip clearing on deeper holes and finish the hole with a light backing cut to reduce splintering on exit.

Usage recommendations

For best results, clamp workpieces securely, pre-mark hole centres and use a pilot centre punch or awl if precise positioning is required. Wear eye protection and dust extraction where necessary, and avoid overheating the bit by using the correct speed and clearing chips regularly.
