Foreword
The text of the International Standard IEC 60745-2-1:2003, prepared by SC 61F (transformed into
IEC TC 116, Safety of hand-held motor-operated electric tools), together with the common modifications
prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116) was submitted to the
Unique Acceptance Procedure and was approved by CENELEC as EN 60745-2-1 on 2002-12-01.
A number of amendments to EN 60745-2-1 have since been voted on and published as amendments
A11, A1 and A12.
A further draft amendment (FprAE) including improvements to the vibration test code and some editorial
corrections, was submitted to the Unique Acceptance Procedure.
The combined texts were approved by CENELEC as a new edition of EN 60745-2-1 on 2010-02-01.
This European Standard supersedes EN 60745-2-1:2003 + A11:2007 + A1:2009 + A12:2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2011-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2013-02-01
This standard is divided into two parts:
Part 1: General requirements which are common to most hand-held electric motor-operated tools (for the
purpose of this standard referred to simply as tools) which could come within the scope of this
standard;
Part 2: Requirements for particular types of tools which either supplement or modify the requirements
given in Part 1 to account for the particular hazards and characteristics of these specific tools.
This European Standard has been prepared under a mandate given to CEN and CENELEC by the
European Commission and the European Free Trade Association and supports the essential health and
safety requirements of the Machinery Directive 2006/42/EC. See Annex ZZ.
Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with
the essential health and safety requirements of the Directive concerned.
CEN/TC 255 is producing standards for non-electric drills and tappers (EN 792-3) and for non-electric
rotary percussive tools (EN 792-5).
Warning: Other requirements and other EC Directives can be applicable to the products falling within
the scope of this standard.
This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2.
This Part 2-1 is to be used in conjunction with EN 60745-1:2009. When this standard states "addition",
"modification" or "replacement", the relevant text in Part 1 is to be adapted accordingly.
Subclauses and figures which are additional to those in Part 1 are numbered starting from 101.
Annexes, subclauses, tables and figures which are additional to those in IEC 60745-2-1 are prefixed “Z”.

Drilling vertically down into a concrete block having the formulation specified in
Table Z105 and having the dimensions 500 mm x 500 mm and 200 mm in height,
supported on resilient material.

minimum thickness of 200 mm. The dust is to be collected.
Tool bit New or sharpened diamond core bit which is in the middle of the rated capacity range.
Feed force The feed force applied to the tool shall be determined as follows:
Drill with the tool increasing the feed force until either the speed is significantly reduced by
the load or a torque limiting device operates. Reduce the feed force slightly until a feed
force is reached enabling stable operation. Use this feed force for the test or 250 N,
whichever is less.
Test cycle The measurement starts when the drill bit has contact with the concrete block or brick wall
and stops after
2 min or,
when the hole is completed, or
when the maximum drilling depth of the core bit is reached.

Part 2-1: Particular requirements for drills and impact drills
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60745-2-1 has been prepared by subcommittee 61F: Safety of
hand-held, motor-opera
...
