1. PRODUCT NAME
Hitachi 10 mm Stud Cutter, Model CL 10SA
2. MARKETING OBJECTIVE
One of the primary uses of studs is for hanging of electric cable racks, air-conditioning ducts, and plumbing pipes
and drains. Studs are usually sold in standard lengths of 1 to 3 meters, and must be cut to desired lengths in
accordance with installation needs. They are currently being cut by cut-off machines, disc grinders, or manual
hack saws, frequently require the use of files and grinders for deburring and finishing before they can be used.
The current Model CL 10D stud cutter is, however, expensive because it is cordless and there is an increasing
demand for a low-price stud cutter with cord. The new Model CL 10SA is a light-weight and low-price stud cutter
adopting the same cam system as that of the Model CL 10D and sharing components with the Model CL 10D2
that is an upgraded version of the Model CL 10D. The Model CL 10SA can correspond to various applications
with the wide selection of cutters (M10, M8, M6 and W3/8).

4-1. Selling Point Descriptions
(1) Clean cutting without sparks, chips and noise
A safer and better working environment without fear of fire or scattering of chips and dust is ensured because the
Model CL 10SA does not produce the chips, dust, and sparks unlike cut-off machines and disc grinders.

(2) Minimal damage to studs permits easy processing
Because of the special cutters employed, few burrs are caused during cutting, and nuts can be attached to the
studs smoothly and easily. Deburring can be done easily and quickly by means of the provided trimmer.
(3) Lightweight
The length of a stud is basically determined by the various needs of the work site. If the ceiling is slanted, for
example, it is hard to determine appropriate lengths. In such a case, it is common to hang studs which are longer
than the required length, and mark and cut them off later. When mounting ducts, up to 20 studs can be cut at a
time at floor level (with a cut-off machine, for example). When mounting luminaiers, however, often only two studs
are cut in one spot. This means that the cut-off machine must be moved from one spot to another over a wide
area.
The Model CL 10SA is compact, lightweight, so it is easily transportable and particularly convenient for cutting off
hanged studs.

(4) Long service life through use of stud cutting edges
Because of the uniquely shaped cutters specially developed by HITACHI, each cutter has four (front, back, upper,
and lower) which can be used in turn for cutting studs. Each cutter is made of high wear-resistant, special steel,
and is capable of cutting up to 500 studs with each of its cutting edges. Accordingly, up to 2,000 studs can be cut
with appropriate use of the four cutting edges.
(5) Excellent working efficiency
In conventional cutting with a cut-off machine or disc grinder, considerable time is required for deburring after the
studs have been cut. In actual tests, the Model CL 10SA is approximately three times more efficient than cut-off
machines or disc grinders.

(6) Minimum cutting length
As illustrated in Fig. 10, it is sometimes necessary to cut studs 30 mm or less from the ceiling surface when
installing fluorescent lamps in electrical installation work. The Model CL 10SA permits cutting protruding studs to
a minimum length of 24 mm from the ceiling surface.
In addition, when installing ducts in air-conditioning equipment installation work, it may be necessary to enclose
the ducts with insulation (lagging) after installation to prevent the formation of dew. In such a case, studs must be
cut as short as possible so that they do not protrude from L-shaped angles, in order to prevent damage of the
lagging. As illustrated, the Model CL 10SApermits cutting of studs within an L-shaped angle measuring 25 mm x
25 mm x 3 mm (t).
(8) Convenient hook facilitates operation in high places
When performing equipment installation work in high places, cutting of
hanging studs is often only one of several jobs that must be
performed. Accordingly, it is sometimes necessary to put the stud
cutter aside and use both hands for some other job. In such cases,
the hook is very useful for hanging the stud cutter from a nearby
conduit, steel grounding material, cable rack, or similar support when
not in use. Fig. 11 Convenient hook facilitates
operation in high places

(7) Equipped with stepless speed control and brake for easy positioning
Before cutting a stud, when setting the open cutter to the desired cutting position, setting can be easily
accomplished by turning on the switch at "Low speed". Also, as the Model CL 10SAis equipped with a brake that
stops the cutter movement in an instant, the cutting operation can be stopped instantly at any desired condition
without worry of unwanted inertial movement after the switch is turned off. Combined use of these two features
provides excellent operability. When cutting a fastened stud (for example, hanged stud in a high place), the cutter
can be closed at "Low speed" and, after ensuring the cutter properly engages the threads of the stud, the cutting
operation can be performed at "full speed". This prevents possible abnormal bite, and ensures clean, accurate
cutting.

(9) Convenient stud mounting hole facilitates cutting studs to specified lengths
The stud mounting hole is very convenient when cutting many studs to the same length at floor level.
The adjustable stud mounting hole permits mounting of M6 to M10 studs, and can be used as an accurate cutting
length guide for the full range of applicable studs. It can be used not only to align cutting lengths to the rear of the
main body, as shown in Fig. 12-(1), but also to align cutting lengths to the front of the main body, as shown in
Fig. 12-(2). The stud mounting hole is particularly convenient when it is necessary to cut several studs at the
same length from, for example, the surface of a ceiling.

(10) Cam-operated auto-return mechanism
After cutting, the cutter is forcibly returned (opened) by means of a plate cam commonly called a "return plate".
This mechanism prevents such malfunctions as the cutter becoming jammed and not returning.
