BS EN 847-1 This document specifies all hazards arising from the design of tools for woodworking machines, and describes themethods for the elimination or reduction of these hazards by tool design and by the provision of information. Thisdocument deals with miling tools (bore mounted, shank mounted, integrated spindle) and circular saw blades, butdoes not cover any hazard related to the strength of shank of shank mounted miling tools.The hazards are listed inClause 5. This document does not apply to boring bits, eccentric single router cutters, cutters with cutting circle lessthan 16 mm and to tools used in rotary knife lathes and copying lathes where the hazard of ejection and contact withthe tool is always prevented by a system of fixed guards andlor movable guards interlocked with guard-locking andlorself-closing guards.

Terms and definitions For the purposes of this document, the following terms and definitions apply.
milling tool rotating cutting tool, (e.g. milling cutter,planing cutter, thicknessing cutter) normally having its main feed directionperpendicular to the rotation axis, for working various surfaces on wood and similar materials through chip removal.
auxiliary cutting parts auxiliary cutting parts are additional cutting parts with a cutting width and a radial cutting edge projection to thebody of less than 12 mm (e.g. grooving inserts, bevelling inserts, chamfering inserts).
spur cutting part which operates both on its periphery and on its flank.The spur projects from the major cutting edge inradial, and if applicable, in axial direction. A spur is either a separate cutting part (see Figure 1) or a part of the ma-jor cutting edge.BS EN 847-1 pdf download.
