Mir Small Bore Boring Bar, CNC Internal Thread Turning Tool A60/A55, Solid Carbide Small Hole Threading Cutter

Mir Small Bore Boring Bar, CNC Internal Thread Turning Tool A60/A55, Solid Carbide Small Hole Threading Cutter. MIR solid carbide small diameter boring bar is developed for micro internal hole machining on CNC Swiss lathe, solving the difficulty of small hole fine turning. Integrated tungsten steel shank structure with high rigidity, effectively suppresses cutting vibration to guarantee hole roundness and high-gloss inner wall finish. One tool supports both internal fine turning and internal thread turning, reducing tool change times and improving machining efficiency. Professionally coated cutting edge, high temperature and wear resistant, greatly extends tool life for continuous machining of stainless steel and titanium alloy. Optimized long neck relief structure, capable of going deep into deep holes and narrow cavities for stable cutting in spaces inaccessible to standard tools. Five-axis precision ground cutting edge with sharp and uniform geometry, reduces cutting resistance and minimizes workpiece burrs. Unique chip breaker design ensures smooth chip evacuation, prevents chip tangling in tiny holes and reduces scrap parts and downtime. Compatible with various hard-to-machine materials, including carbon steel, stainless steel, titanium alloy, tempered steel and copper alloy. Standard straight shank design for simple and fast clamping, compatible with most mainstream CNC Swiss lathes with strong versatility. Widely applied in medical components, electronic connectors, aerospace precision parts and miniature hydraulic parts industries.
