Useful in confined spaces due to the pointed nose.Application areas encompass machining cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper and aluminium.DIN: SPG.Fine: for hard and/or tough materials where a smooth surface finish is required and removal demands are modest.Medium: for machining hard and/or tough materials under normal conditions.Coarse: particularly suitable for machining stainless steel, soft materials or light alloys.Extra coarse: blunt.X-Cut: for hard and soft materials, produces short and blunt chips, runs smoothly even at low cutting speeds.Diamond cut: for heat-treated and tough alloy steels and epoxy, excellent finish, minimal axial forces.A smaller diameter burr will have a finer cut than a larger diameter burr belonging to the same cut category, for example, medium-cut.Stock standard: X = yes.Indispensable tool, used in large number of industrial sectors including aviation, shipping, automotive and the chemical industry etc..Used to deburr irregular objects or to complete finishing work inside a confined space.Number of teeth is also indicated in addition to the type of cut for each rotary burr.Deburring of surfaces with round edges and surfaces
