BLACK and CHROME coatings are among the most advanced PVD (physical vapor deposition) technologies, having specific characteristics for each type of cut.

These coatings increase surface hardness, wear and temperature resistance, and decrease friction generated during cutting, providing:

• High performance
• Shorter cutting time
• Increased productivity
• increased health

BLACK COATED

The ideal choice for cutting conditions where the saw is subjected to high levels of load under high temperatures. A high hardness, coupled with great toughness, provides excellent protection against erosion and abrasive wear. Its nano structure ensures a low coefficient of friction ideal for high cutting speeds.

CHROME COATED

This coating has been specially developed for the most demanding cutting conditions. Its microstructure results in an extremely resistant and stable coating, providing superior results in dry cutting. Its resistance to oxidation under high temperatures allows for even higher cutting speeds and feed rates.

TYPE A

Type A tooth is typically used for milling applications in non-ferrous alloys, jewelry, and screw slots.

AW TYPE

The type AW tooth, unlike type A, is highly chamfered, thus optimizing chip breakage. It is particularly suitable for higher removal rates.

TYPE B

The type B tooth is usually used on thin saws for cutting very thin-walled pipes, where chip removal is not a problem.

BW TYPE

The BW tooth type is used for cutting pipes and profiles with greater wall thicknesses. The tooth is alternately chamfered at 45°, breaking the chip in two parts and ensuring good drainage.

BS TYPE

The BS tooth type has been developed for cutting low-thickness pipes. It has twice the number of cutting edges ensuring a better finish for the section.

TYPE C

Type C tooth is used for solid sections or very thick-walled pipes. The chip is broken into three parts. A slightly higher tooth, with two chamfers, one on each side, is responsible for the pre-cut. The next tooth, without chamfer, is responsible for the finish.

VP TYPE

The VP tooth has variable pitch, it is used to cut very irregular sections that cause vibrations and noise. It ensures a smoother contact and offers great durability with reduced vibration.

The choice of the type of sharpening and its cutting angles is of fundamental importance, as it is related to the requirements of cutting finish and tool durability.
