KEUE CNC Small Diameter Carbide MTR Boring Cutter Bar Light Cutter Copper Application Machining Inner Boring Tool
This MTR small-bore internal boring bar is made of premium solid tungsten carbide with uncoated polished finish. Specially engineered for copper and aluminum non-ferrous metals, it delivers outstanding cutting rigidity for high-precision micro inner-hole boring on Swiss-type CNC automatic lathes.
The razor-sharp uncoated cutting edge effectively avoids material adhesion and built-up edge when processing soft metals. It guarantees smooth chip removal in confined narrow bores, achieving superb surface finish and consistent dimensional precision for copper and aluminum workpieces.
Its slim high-rigidity shank perfectly adapts to the extremely limited working space of micro bores. Available in various specifications, it prolongs tool service life, cuts tool-change downtime, and significantly improves overall productivity for mass manufacturing of miniature precision parts.
