Equalizer Z3 Blade 1-1/2 (Pkg 5)

Equalizer Z3 Blade 1-1/2 (Pkg 5)These innovative blades will remain flexible and retain their sharpness much longer than the average cold knife blade. The grinding of the blade is at a greater angle than other cold knife blades. This makes the resistance less when pulling the cold knife to cut the urethane. The end result is a cold knife blade that has the ability to resist breaking, last longer, and keep a sharp edge. Equalizer produces two types of cold knife blades. Both the

These innovative blades will remain flexible and retain their sharpness much longer than the average cold knife blade. The grinding of the blade is at a greater angle than other cold knife blades. This makes the resistance less when pulling the cold knife to cut the urethane. The end result is a cold knife blade that has the ability to resist breaking, last longer, and keep a sharp edge. Equalizer produces two types of cold knife blades. Both the standard and the coined blades use the same proprietary hardening process.

The Coined Z Blade... The cutting surface of a coined cold knife blade has the cutting surface of the blade made thinner, only about 35 thousandths of an inch thick. A normal cold knife blade is 62 thousandths thick. Many technicians routinely grind cold knife blades thinner so they will cut easier. Sometimes this grinding will overheat a blade and damage the hardening. Coined Z blades are thinned before they are hardened so there is no need to grind them thinner.

Should I buy coined or not coined blades?

If you use a cold knife blade right out of the box and never grind it thinner, then use the standard thickness Z1, Z2, Z3, or Z7. If you like to take a new blade and grind it thinner before you use it, then you should purchase the "pre-thinned" Z4, Z5, Z6, or Z8.
