Abstract

The invention provides a method of, apparatus for, flush­ ing with water a mineral cutter pick of the kind having a head (5) terminated with a hard cutting tip (6), in which one or more jets of water (13) are directed from nozzles (12) in the pick holder (8) at the pick at an acute angle to the head of the pick so that the water strikes (14) the pick head and is carried for­ ward over the surface of the pick head by its own momentum into the vicinity of the cutting tip.
