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).
