Make clean, accurate conical holes with this 4pc countersink deburring bit set. These bits leave smooth, burr-free edges on a variety of materials with an 82-degree chamfer that creates a perfect recess for countersunk screw heads.

The set includes four bits with sizes ranging from 2mm to 20mm to meet all your drilling needs. Compatible with wood, plastic, aluminium and other non-ferrous metals.

Chip removal through the slot prevents excess waste from clogging the workpiece. Ideal for burr and chatter-free deburring and countersinking which makes them more efficient than a standard countersink.
