Countersink Bits & Reamers (10)
Countersink bits & reamers are designed to fit directly into manual, electric and cordless drill driver attachments and they have hexagonal or round shanks. These bits are used to create a chamfer around the rim of a pilot hole enabling the head of a countersunk screw to fit flush.
Our range includes various multipacks of countersink bits, pilot drill bits and screwsink sets. These provide different-sized bits, ensuring the correct size is always easily available. We supply multiple countersink bits that are designed for creating a clean hole in a surface whilst leaving a wider area at the top, so a screw can be fitted with a completely clean finish.
Screwsinks are supplied with a hexagon key, and they are ideal for countersinking and counting-boring, the hex key is used to adjust the depth of the hole being drilled by fitting into the countersinking part so it can be slid up and down. There are multiple sizes of these available within our selection.
