Precision Miniature Boring Bars for Micro Machining

High-quality tungsten steel construction ensures exceptional durability and wear resistance for prolonged tool life. Ultra-fine 3mm cutting edge delivers surgical precision in small bore turning operations, ideal for intricate CNC machining of delicate components.

Mirror-polished MIR/MUR series features advanced anti-vibration grooves that minimize chatter during high-speed operations. Perfect for watchmaking, medical instruments, and aerospace micro-parts manufacturing where sub-millimeter accuracy is critical.

Compact 8mm shank diameter allows access to tight spaces unreachable by standard boring tools. Includes proprietary nano-coating that reduces built-up edge formation when working with stainless steel and titanium alloys.

Engineered for bench lathes and Swiss-style CNC machines handling miniature turned parts. Ships with certified hardness testing report (62-64 HRC) and factory-preset cutting angles for immediate plug-and-play performance.

Direct-from-factory pricing with bulk order discounts available for machine shops and OEM part manufacturers. Global logistics network guarantees same-day dispatch from our bonded warehouse facilities.
