How to use

Secure the workpiece and mark the drilling point. Fit the Dedra DED1529Q12 into a compatible drill chuck and tighten. Select a drill speed appropriate to the material: lower speeds for glass and masonry, medium speeds for aluminium and plastic, and higher speeds for most woods. Apply steady, even pressure and avoid excessive force. For glass and tile, use coolant or water and consider backing the piece to prevent chipping. Withdraw the bit periodically to clear debris from the hole when drilling deeper openings.

Usage recommendations

Use suitable personal protective equipment such as safety glasses and gloves. Match drill speed and feed to the material, and use lubrication or cooling when drilling metal or glass. Inspect the bit before use and replace if worn or damaged to maintain hole quality and safe operation.
