APPROXIMATE CUTTING RATES

Material

Cutting Rate

Concrete – 6 in (15 cm)

5 lineal in/min (12 cm/min)

Red Brick – 6 in (15 cm)

10 lineal in/min (25 cm/min)

Rebar – #4 (12 mm)

*Rebar must be encased in concrete, never cut bare rebar.

INCH-FOOT DEFINITION

An in-ft is a measure of how much material is to be cut.
An in-ft is defined as: depth in inches times length in
feet.
Note: 129 in-ft = 1 m

Example: How many in-ft are in this doorway?

1. Determine the depth of the cut in inches.

For this example, 8 inches.

2. Determine the length of the cut in feet.

3+7+3+7=20 feet

3. Multiply the two numbers

8 in x 20 ft = 160 in-ft
