Tungsten Carbide Burr for Left-Handed Use, 3.175 mm, 2 Flutes

【Left-Handed Milling Cutters】2-flute geometry designed for climb milling of aluminum and non-ferrous materials: the left-hand helix evacuates chips upward, preventing re-cutting and binding on the workpiece.
【Tungsten Carbide】Made of micro-sintered carbide, this milling cutter withstands the heat generated by high-speed machining and resists edge wear much longer than standard high-speed steel cutters.
【Blue PVD Coating】The nano-coating reduces built-up edge friction on soft alloys, providing smoother wall finishes and preventing chip adhesion during deep grooving.
【3.175 mm Round Shank】Precision universal 1/8" shank fits ER chucks, CNC spindles, and rotary tool holders, without the need for bushings or of special adapters.
【Compact 40mm Profile】The reduced overall length increases tool rigidity for engraving and detail work, minimizing deflection on small CNC milling machines and desktop engraving machines.
