Product Description Diamond & CBN Honing Stones, Mandrels for Hardened Steel & Carbide Bushings Inner Bore Honing Product DescriptionHoning is often applied to the inner bores of drill bushings to achieve high dimensional accuracy, roundness, and superior surface finish. Drill bushings are critical components used to guide cutting tools such as drills and reamers during machining. In high-precision applications, even minor deviations in the bushing's bore can lead to tool misalignment, hole inaccuracy, and increased wear.By honing the inner bore, manufacturers can achieve tighter tolerances (e.g., H5-H6), improve cylindricity, and reduce surface roughness (Ra < 0.2 μm). This ensures smooth tool entry, consistent positioning, and extended service life of both the bushing and the cutting tool.Honed drill bushings are widely used in aerospace, automotive, mold making, and precision machining industries, where accuracy and repeatability are essential.
