BRIEF HISTORY
The IS0 Recommendation R 1 1 17, Bonded abrasive products - Grinding wheel dimensions (Part 2), was
drawn up by Technical Committee ISO/TC 29, Small tools, the Secretariat of which is held by the Association
Française de Normalisation (AFNOR).
Work on this question led to the adoption of a Draft IS0 Recommendation.
In June 1968, this Draft IS0 Recommendation (No. 1596) was circulated to all the IS0 Member Bodies for
enquiry. It was approved, subject to a few modifications of an editorial nature, by the following Member Bodies :
Australia Italy Switzerland
Belgium Japan Thailand
Czechoslovakia Netherlands Turkey
France New Zealand U.A.R.
Germany
Peru United Kingdom
Greece U.S.A.
Poland
Hungary Portugal
U.S.S.R.
India South Africa, Rep. of Yugoslavia
Ireland Spain
Israel Sweden
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council, which decided,
in September 1969, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 1117 September 1969
BONDED ABRASIVE PRODUCTS
GRINDING WHEEL DIMENSIONS
(PART 2)
!NTRODUCTION
This IS0 Recornmendation is i1 continuation of 1SO Recommendation R 603, Bonded abrasive products - Grinding
wheel diniefisions (Part 1 j.
Save for the exceptions indicated by a reference mark, the dimensions retained for the wheels specified in this
IS0 Recommeridation are those provided in IS0 Recommendation R 525, Bonded abrasive products - General
features - Designation - Ranges of dimensions - Projïles and in its Addendum 1, Dimensions of the wheel holes
for special applicatiors and tolerances.
The numerical values retained in this IS0 Recommendation are given in both systems of units (metric and inch).
The holes being identical, wheels of the metric series and those of the inch series can be mounted on the same
machines; however, the overall dimensions possibly being slightly different, wheels of both series can only be consid-
ered as equiva!ent.
The symbols for dimensions used in the figures and tables are those provided in IS0 Recommenda:ion R 603. They
may be redaced in national standards by those in conformity with the rules prevailing in the country concerned,
until internationa: agreement regarding a single reference system is reached.
The figures accompanying the tables are only rough sketches which permit reference to the useful dimensions;
particularly, for cup grinding wheels and for plain grinding wheeis with a recess, the inset angles should be replaced by
a fillet to avoid any initiation of rupture, but permitting, however, correct application of the pieces on the shaft.

1.2 Driiiing
The drawings on pages 8 to 21 correspond to the drillings and to the boring of the fixing plate seen from
the face.
Some of the nuts may be omitted in the wheels but it is recommended that such as are used should
correspond to one point of the drillings provided for.
For wheels with a diameter D of 300, 350,400,450, 500,600 and 750 mm, or of 12, 14, 16, 18,20,
24 and 30 in, the nuts are equally spaced on the corresponding circle.
The dimensions of the nuts should be indicated on the wheels.
