A range of industrial quality hollow square mortice chisel sets, comprising chisel and auger. Manufactured from high quality hardened and tempered carbon steel. Chisels are finely ground and polished with honed cutting edges. Chisel shank diameter (F) is 13/16 inch. Available in Imperial sizes only, but metric equivalents are shown. Chisel sets are supplied with the auger shank overlength to suit most machines. This will need to be shortened before the first use - for details click the link below.N.B. Please be aware that the auger bit shank diameter 'G' may not suit machines that use sleeves and a lock screw to fix (e.g. Multico). The bore of the sleeve MUST match the auger shank dimension.
