Tungsten carbide Reamer with spiral flute

Our tungsten carbide reamer with spiral flute is a high-performance precision finishing tool engineered for accurate hole sizing and smooth surface machining, widely applied in CNC lathes, machining centers and mold manufacturing. Integrated solid tungsten carbide substrate delivers extreme hardness and outstanding wear resistance, supporting continuous high-speed cutting.

The optimized spiral flute design enables smooth chip evacuation, effectively preventing chip accumulation that scratches inner hole walls. Uniform spiral angle reduces cutting vibration, guaranteeing tight tolerance within H7/H8 standards. Standard technical specs cover diameter 3mm–32mm, straight shank and Morse taper shank options, customized lengths and flute pitches are acceptable.

Compared with straight flute reamers, spiral flute carbide reamers boost processing efficiency by 40% and extend tool lifespan greatly. They leave burr-free mirror inner surfaces without secondary polishing, lowering production cycle costs. Perfect for carbon steel, stainless steel, cast iron and hard alloy workpieces. We provide factory direct bulk supply and custom coating service including TiN, TiAlN for heavy-duty industrial machining.
