The Brush Research Manufacturing FLEX-HONE® BC Series Standard Duty is a precision honing tool engineered for finishing, deburring, and surface conditioning in small-diameter bores. Designed for a 0.433" (11mm) hole diameter, it delivers consistent, controlled abrasive action using 320-grit Aluminum Oxide abrasive globules. The flexible construction allows the tool to self-center and conform to the bore geometry, producing a superior surface finish without the need for rigid fixturing. It is well suited for use on aluminum, brass, bronze, and other softer non-ferrous materials across automotive, hydraulic, and precision machining applications.

BC Series Standard Duty construction is compatible with aluminum, brass, bronze, and softer non-ferrous materials
