DIA/CBN Bars（Classification：Internal Grindstone）

Diamond/carbon burs are rod-type abrasives used for grinding the inner surface of metals and nonferrous metals and removing burs. They are mainly used for the precision grinding of molds and other workpieces and finishing of welds. They are attached to precision grinders (micro grinders) to be used. Bar tips are available in various shapes, including cylinder shape, ball shape, bullet shape, flat shape and tapered shape, and it is important to choose a suitable type according to the application. Products with a hexagonal shaft can be used attached to an impact screwdriver. Carbon is second to diamond in hardness, and like diamond, it is used as a material for abrasive grains. Carbon is frequently used for stainless steel and other metal materials, and due to its excellent heat resistance, carbon is suitable for use under high temperatures.

Borazon Internal Bar

TRUSCO

[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.

Standard Price:	MYR 73.24
Days to Ship:	3 Day(s) or more

Diamond internal bar

TRUSCO

[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.

Standard Price:	MYR 44.36-

High End Black Bar #325

TRUSCO

[Features]
· For finishing, chamfering.
· Special high-hardness stainless steel shank realizes firm operability and suppleness.
· Capable of precision machining thanks to the shank, which bends less.
· Machining time is significantly shortened as work can be done with high loads.
