The object of this book is to give an account of such Tools
as are commonly used by Engineers and Woodworkers, written
chiefly from the standpoint of the men who have to use them,
and who desire to understand the principles which underlie
the forms in which those Tools are found.
instructions for their employment, as suggested by the
writer's own experience, have been added. The work (it is
believed) is more comprehensive in its scope than any which
has preceded it, the subject of Instruments of Measurement
being treated in a very full manner and freely illustrated
(as are all sections of the work) with drawings of leading
Although, in strictness, Tools and Measuring Instruments
form distinct groups, they cannot be separately regarded in
shop practice, since modern methods of measurement are
directly related to certain systems of manufacture, both
general and special in character.
The subjects treated here have never previously assumed such
great importance as in recent years. Tool-making has been
developed into highly specialised branches of manufacture,
different firms taking up different classes or groups of
Tools and Instruments, with the perfection of results and
fine precision that come of specialization. Some of these
results will be found here illustrated in book-form for the
The great and growing importance of Cutting Tools in modern
practice is evidenced by the numerous experiments to which
they have been subjected. But the experience of the shops
still remains of highest value, and only in very general
terms can these experiments be applied as yet to practical
As they relate to Lathe Tools chiefly, some account
of them will be found in another work (now in the press) by
the same Author, dealing with "Engineers' Turning."
It should be mentioned that a large part of the matter
included in this volume consists of selections from various
articles contributed by the Author to the English Mechanic
and the Mechanical World, which have been carefully revised
and supplemented where necessary, but several chapters are
chiefly or entirely new, and a substantial proportion of the
illustrations given have been specially drawn and engraved
for the work.
