DIN333 HSS Centre Drill Bit 60 Degree Combined Countersink Spotting Drill
Center drill bits, also known as Slocombe drill bits, are used in metalworking to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a workpiece in which to mount a lathe center. In either use, the name seems appropriate, as the bit is either establishing the center of a hole or making a conical hole for a lathe center. Nevertheless, because of the frequent lumping together of both the terminology and the tool use, suppliers may call center drill bits combined-drill-and-countersinks in order to make it unambiguously clear what product is being ordered.
1.Double ended tool for centreing prior to drilling or for producing a countersink from, for lathe centre location.
2.Suitable for both hand and machine use.
