Heavy Metal Boring Bars are manufactured from sintered alloy of 95% tungsten with a nickel-copper-iron matrix. This alloy is very similar to tungsten-carbide but the chemical composition was developed differently to reduce embrittlement. The high density (twice as heavy as steel) and tensile strength (110 kpsi) of this alloy makes an ideal combination for chatter-free tools. Heavy metal boring bars greatly enhance boring applications by absorbing vibration and drastically reducing chatter, allowing machining of deeper bores with improved finish and precision.
