One of the most impressive material characteristics of cemented carbide is its stiffness compared to steel. This property is expressed in engineering terms as Modulus of Elasticity or Young's Modulus. All steel materials have a Young's Modulus value of 30,000,000 psi whereas cemented carbide has a value of 94,000,000 psi. Thus, carbide is 3 times more rigid, or "stiffer", than steel. No other application takes better advantage of this distinguishing physical property than a boring bar application.

The boring bar must extend inside a cylinder's bore, or inside diameter, for extreme lengths while performing a metalcutting operation with minimal deflection to reduce chatter and vibration. General Carbide has many years of experience in producing high-quality boring bar blanks with material characteristics that meet customers' exacting specifications. We can produce as-sintered blanks or blanks with a ultility grind to make it easy for your final finishing operations and brazed attachments.
