Material
The material the boring bar is made of. Choosing the right material for your workpiece can shorten work time, reduce cost and prevent premature wear.

Brazed Carbide (13)
Brazed carbide cuts faster than high speed steel and is made of a strong and durable material. The carbide head is brazed onto the end of the steel shank. It is commonly used on ferrous and non-ferrous metals including cast iron, steel and steel alloys.
Carbide-Tipped (361)
Carbide tips cuts faster than high speed steel and they are made of a strong and durable material. The carbide tip is brazed onto the steel head of a shank. It is commonly used on ferrous and non-ferrous metals including cast iron, steel and steel alloys.
CBN-Tipped (38)
CBN tips are similar in hardness to diamond. They are commonly used for machining hardened steel and related alloys at high temperatures.
Cobalt (126)
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Diamond-Tipped (33)
Diamond tips are one of the hardest cutting materials. They are brazed onto a carbide insert. They are commonly used at high cutting speeds on non-ferrous metals.
High Speed Steel (30)
High speed steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
Solid Carbide (933)
Solid carbide provides better rigidity than high speed steel. It is extremely heat-resistant and used for high-speed applications on cast iron, non-ferrous materials, plastics, and other tough-to-machine materials. It is commonly used in high performance applications.
 
Material Grade
Material grade is an industry standard identification for chemical composition and hardness of the metal.
