General Information
The tool series is designed to drill 5/16 head Hex screws from ½ inch up to 1-½
inches long and a variety of wood to metaland “metal to woodscrews with head
diameters of up to about 15/32 diameter with Square and some Phillips recesses. For metal
applications, the screws must fit the bit quite well, so if bits get worn, replace them for best
results. Muro North America Inc 1800-665-6876 can provide a wide variety of screws to
meet your volume screw requirements.
Magnetic bits are recommended for the CH7260 metal pro tool only if the tip of the
screw is more than 3/8 of an inch from the metal being driven. For proper application,
versions of the metal pro tool with a shortened screw guide or additional chip clearance are
available to provide a custom tailored solution for your application (see CH7260 Series, page
13).
The MK6827 or HITACHI W8VB driver is recommended to work with the CH7260
Metal Pro attachment because they accept the hex bit directly. The 6827 torque adjustability
is required to allow Hex fasteners to be reliably driven without strip out in thin materials.
For thick (1/4-1/2) steel (Tek 4/5) applications the 1700-rpm HITACHI W8VB driver is
recommended. Very thick steel (3/8-1/2) usually requires screws with milled sides for
tapping as the tapping torque is high.
The Muro belt pouch provides a convenient way to carry a large number of strips
around easily while using the tool. An optional stand up extension Rod handle attachment is
available and can be added at any time.
