Micro 100 BB-100300 Boring Bar

The Micro 100 BB-100300 is a carbide boring bar intended for precision internal machining operations. Its C2 micrograin carbide construction provides hardness and wear resistance for cutting tasks. The tool suits machinists and fabricators who require a small-diameter bar for tight boring applications.

Practical limits of the uncoated carbide bar

The bright uncoated surface means the bar lacks a protective coating that reduces friction or extends life in high-heat cuts. Users must supply appropriate cutting fluids and speeds to manage temperature. It is not suited for buyers who need a coated tool for prolonged production runs or for those who require a larger shank diameter than the one this model provides.
