European foreword
This document (EN 847-1:2017) has been prepared by Technical Committee CEN/TC 142
“Woodworking machines - Safety”, the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2018, and conflicting national standards shall be
withdrawn at the latest by May 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 847-1:2013.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
Introduction
The extent to which hazards are covered is indicated in the scope of this document.
The requirements of this document concern designers, manufacturers, suppliers and importers of tools
for cutting wood and materials with similar physical characteristics to wood.
This document also includes information that the manufacturer will provide to the user.
1 Scope
This European Standard specifies all hazards arising from the use of tools for woodworking machines,
and describes the methods for the elimination or reduction of these hazards by tool design and by the
provision of information. This European Standard deals with milling tools (bore mounted, shank
mounted) and circular saw blades, designed for chip removal machining (cutting) of wood and
materials with similar physical characteristics to wood, hereinafter referred to as “tools”. The hazards
are listed in Clause 4.
This European Standard does not cover any hazard related to the strength of shank of shank mounted
milling tools.
This European Standard does not apply to boring bits, eccentric single router cutters, cutters with
cutting circle less than 16 mm and to tools used in rotary knife lathes and copying lathes where the
hazard of ejection and contact with the tool is always prevented by a system of fixed guards and/or
movable guards interlocked with guard-locking and/or self-closing guards.
This European Standard is not applicable for tools according to this scope, which are manufactured
before the date of its publication.
NOTE For woodworking machines and materials with similar physical characteristics to wood, see
ISO 19085-1.

3 Terms, definitions, symbols and abbreviations
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
milling tool
rotating cutting tool (e.g. milling cutter, planing cutter, thicknessing cutter) normally having its main
feed direction perpendicular to the rotation axis, for working various surfaces
Note 1 to entry: The cutting edge of the cutting part can be
- parallel to the axis of rotation,
- square to the axis of rotation, or
- a profile which is a combination of the two.
The tool can be
- a one-piece tool,
- a composite tool,
- a complex tool, or
- in the form of a tool set.
3.1.2
circular saw blade
rotating cutting tool for cross-cutting or ripping
Note 1 to entry: The tools cut on the periphery and on both flanks simultaneously, and can be
- a one-piece tool,
- a composite tool,
- a complex tool, or
- in a form of a stack of circular saw blades with equal diameter.
3.1.3
one-piece tool
tool without bonded or detachable parts: the body and the cutting parts are one-piece
3.1.4
composite tool
tool where the cutting parts (tips) are firmly connected by bonding to the body, e.g. welding, brazing,
adhesive fixing
3.1.5
complex tool
tool where one or more cutting parts are exchangeably mounted in a body through detachable fixing
elements
Note 1 to entry: The cutting parts can be one-piece or composite.
3.1.6
tool set
one or more individual tools (e.g. milling tool, circular saw blade) clamped together on a tool carrier
(e.g. sleeve, arbor) designed to function as one tool
3.1.7
shank tool
tool with integrated shank (e.g. cylindrical, HSK, taper)
3.1.8
integrated tool
milling tool where the body is part of the machine and only the cutting parts are exchangeable
3.1.9
body
part of the tool which holds the cutting parts or on which the cutting parts are formed
3.1.10
cutting part
functional part or parts of the tool each comprised of chip producing elements
Note 1 to entry: The cutting edges, face and flank are therefore elements of the cutting part. In the case of a
multi-toothed cutter tool, each tooth has a cutting part.

auxiliary cutting part
additional cutting part with a cutting width of less than or equal to 12 mm and a radial cutting edge
