(1) Rapid cutting speed (6.3 m/min):

As shown in the table below (based on comparative cutting of 1.6 mm [1/16"] mild steel plate), the cutting

speed of the Model CE 16SA is the fastest in this class of hand shears.  This is because of the high stroke

speed of the piston during actual cutting operation; the more powerful motor minimizes stroke speed loss

when the load is increased.  The much higher cutting speed of the Model CE 16SA in comparison with B and

C.

For further details concerning the relationship between the cutting speed and the number and the length of the

piston strokes, refer to the explanation of cutting speed below.

 (NOTE) Actual cutting speeds may vary depending on the hardness of the workpiece material, the skill of the

        operator, and other variables.

From the formulae above, it can be clearly seen that increases in the values of "N" and "H" will result in faster

cutting speeds.  However, it should be noted that the amount to which these values can be increased is

limited by the bounds of existing design technology.  In addition, please note that there is very little difference

in the value of the constant "C" among the various manufacturers.

The housing is easy to grip and use because the

grip circumference is 24 mm shorter than the

conventional model, 11 mm shorter than B, and

16 mm shorter than C.
