H.B. Carbide Company, a unit of the Star Cutter Co., is recognized as the leading top source of tungsten carbide preforms for manufacturing cutting tools.  By consistently producing preforms with minimal grind stock, H.B. Carbide increases customer productivity while reducing cost.

H. B. Carbide offers many different grades of tungsten carbide, manufactured under process certification ISO 9001:2000. 

By using the preforming expertise at H.B.Carbide, major portions of carbide can be removed from the tool blank while the carbide is in the 'green' state. Drilling of coolant holes, prefluting, and grinding different diameters can be accomplished in seconds at HBC as compared to the slow process of grinding in the 'hard' state. Therefore, we can leave minimal grindstock for you to finish grind. This reduction in grinding time saves you grinding wheel life and increases machine capacity allowing you higher productivity.

These blanks can include, but are not limited to:

• Straight Flutes
• Spiral Flutes
• Coolant holes (in any location)
• Stepped Diameters
• Centers (male or female)
• Flats
• Chamfers
• Keyways
• PCD Pockets
• Preformed sharpening angles
