5-1-5. Variable-speed switch
A manual cutter/bender has an advantage of hand-adjustable bending by eye measurement. Since the Model
VB 13Y uses a variable-speed switch, rebars can also be bent to the desired angles by eye measurement with a
manual-like feel while the conventional electric bender provides only a fixed-speed bending. The operator can
easily vary the bending speed depending on how far the switch trigger is depressed. These features make the
Model VB 13Y convenient for bending work at construction sites.
5-1-6. Built-in microprocessor
The Model VB 13Y is equipped with a microprocessor for uniform bending angles over a wider range of speeds
from low to high. Rebars can be bent according to the angles selected with the setting dial even if the bending
speed is varied. The Model VB 13Y provides uniform bending results regardless of speeds and the motor's
inertial force.
5-1-7. Double-insulated structure
The Model VB 13Y has double-insulated structure for safety in use outdoors or below the ground.
5-1-8. Reaction receiver
There is a need to prevent movement of the unit caused by cutting 5 m (197")-long rebars generally used in
construction sites. The Model VB 13Y has two reaction receivers at the front and the rear for stable operation.
5-1-9. Hole for bolting to a fixed base
A hole is provided at the center of the unit to fix and stabilize it. This hole comes in quite handy for bending
operations because it allows the unit to be bolted to a suitable work bench (bolt size M10, less than W3/8).
5-1-10. Low height
The Model VB 13Y has a unique design, with the bending unit being lower than the motor unit, to give the bender
added stability when bending long rebars. Although the maximum capacity rebar diameter is smaller than another
maker's electric cutter/bender, the Model VB 13Y is convenient to use thanks to its lower height (135 mm (5-5/
16")) while the other maker's electric cutter/bender is 245 mm (9-41/64") high.
5-1-11. Center plate with marking for bending position adjustment
The Model VB 13Y eliminates manual marking work
