1st Machine Tool Accessories is offering the XPS-16 four-axis CNC drill sharpener from Darex, which is capable of processing a range of tools, including conical, four facet, split point and radius split point twist drills manufactured from materials such as steel, cobalt and solid carbide.

The unit can restore drills with angles of 90–150º, lengths of 51–254mm (2–10in) and a diameter of 3–16m (1/8–5/8in) in a one-touch operation.

A blunt drill is inserted into the sharpener’s chuck and the required standard or drill type can be selected using an LCD touchscreen panel. Three electronic sensors then detect the drill’s length, locate the cutting edge and calculate the web thickness.

The drill is then sharpened and the required split point form applied in one operation without operator involvement.

As part of the automatic process, it also hones carbide drill edges.
