Borazon Internal Bar

Trusco Nakayama

[Features]
· Shank diameters of 3 mm.
· Knoop hardness is about 4,700 (second hardest material following diamonds) so CBN can be used just as diamond for most workpieces; however, it generates large amounts of heat especially during grinding, so it is best suited for metals containing carbon.
[Applications]
· Applicable workpiece materials: Carbon steel, tool steel alloy, high-speed tool steel, bearing steel, case hardened steel, hardened steel, stainless steel.

Diamond Internal Bar

Trusco Nakayama

[Features]
· Shank diameters of 3 mm.
· Knoop hardness is about 7,000 (the hardest material on earth) so it can be used for most workpieces such as metals, marble, glass, etc. Most suited for workpieces with high hardness such as ceramic materials. However, since diamond does not withstand heat, it is not suitable for machining that involves production of large amounts of heat (HSS, etc.).
[Applications]
· Applicable workpiece materials: Carbide alloy, glass, ceramic, rubber, plastic, stone, concrete, ferrite and other nonferrous metals.

Internal Bar 5-Piece Set (Borazone)【5 Pieces Per Package】

Trusco Nakayama

[Features]
· Borazon (CBN) is an abrasive grain that has hardness second to diamond. Suitable for iron based materials (stainless steel, SC, SK, SCM, etc.) for which diamond is not suitable.
· Also suitable in cases where sufficient cooling is not possible, as its heat-resistant temperature is higher than that of diamond.
[Applications]
· Applicable workpiece materials: Carbon steel, tool steel alloy, high-speed tool steel, bearing steel, case hardened steel, hardened steel, stainless steel.
