We have made it our mission to
invest in the resources, technology,
and people that enable us to
provide these qualilty application products,
the Cleveland Brand.
The Cleveland® brand is well-known throughout the world for its wide
selection of premium cutting tools for drilling, countersinking, reaming,
threading, and milling operations.
Its roots go back to the 1870's, when Cleveland Twist Drill was
established as a premier cutting tool company in the United States.
Cleveland has always been famous for the quality and
reliability of its tools, and the company grew to be one
of the largest high-speed steel toolmakers in
the US, expanding to overseas markets.
In 1995, Cleveland Twist Drill was acquired by
Greenfield Industries Inc. (GFII), a U.S. based
manufacturer of precision cutting tools.
Today, Greenfield Industries is part of TDC,
the world’s largest manufacturer of twist drills.

Metal Cutting Safety (read this before using Cleveland® products)
Modern metal cutting operations involve high energy, high spindle or cutter speeds,
and high temperatures and cutting forces. Hot, flying chips may be projected from the
workpiece during metal-cutting. Although advanced cutting tool materials are designed
and manufactured to withstand the high cutting forces and temperatures that normally
occur in these operations, they are susceptible to fragmenting in service, particularly
if they are subjected to over-stress, severe impact or otherwise abused. Therefore,
precautions should be taken to adequately protect workers, observers and equipment
against hot, flying chips, fragmented cutting tools, broken work pieces or other similar
projectiles. Machines should be fully guarded and personal protective equipment should
be used at all times.
When grinding advanced cutting tool materials, a suitable means for collection and disposal
of dust, mist or sludge should be provided. Overexposure to dust or mist containing
metallic particles can be hazardous to health particularly if exposure continues over
an extended period of time and may cause eye, skin and mucous membrane irritation
and temporary or permanent respiratory disease. Certain existing pulmonary and skin
conditions may be aggravated by exposure to dust or mist. Adequate ventilation, respiratory
protection and eye protection should be provided when grinding and workers should
avoid breathing of and prolonged skin contact with dust or mist.
General Industry Safety and Health Regulations, Part 1910, U.S. Department of Labor,
published in Title 29 of the Code of Federal Regulations should be consulted. Obtain
from Cleveland® and read the applicable Material Safety Data Sheet before grinding.
Cutting tools are only one part of the worker-machine-tool system. Many variables exist
in machining operations, including the metal removal rate; the workpiece size, shape,
strength and rigidity; the chucking and fixturing; the load carrying capability of centers;
the cutter and spindle speed and torque limitations; the holder and boring bar overhang;
the available power; and the condition of the tooling and the machine. A safe metal
cutting operation must take all of these variables, and others, into consideration.
Cleveland® has no control over the end use of its products or the environment into
which those products are placed. Cleveland® urges that its customers adhere to the
recommended standards of use of their metal cutting operations. The information included
throughout this catalog under the heading “Technical Data” and other recommendations
on machining practices referred to herein are only advisory in nature and do

particular work environment or application.
