Ultra micro-grain quality carbide tools series
High precision reamer

◆.High precision profile (compound) reamer series by solid ultra micro grain quality carbide(1-18 flutes, straight edge, oblique edge)
※We can also produce SKH4C/ASP60 series according to drawings, samples, size tolerance.
●.We used of advanced strong high speed CNC from Germany & Switzerland & high precision profile grinding (3DXTec)by ultra strong quality carbide. Have perfection quality of edge and size tolerance up to ±0.001mm(±1μm) high.
 
●.High precision products, surface roughness≤Rα0.15μm, concentricity⊙≤3μm
●.Grades
   ★.High impact resistance diamond tungsten steel(for intermittent cutting)VRA201/VRA221/VRA441。
   ★.High hardness quality carbide (for super high wear resistance)HRF10/NRB10Z
 
   ★.Tungsten steel meeting ISO standard (for general machining)MR11/PR40
●.For all kinds of high-hard material HRC50°~64°& non-ferrous metals , light alloy and high requirement wear-resistance reamer machining.
  Mid-low speed intermittent reaming machining for stainless steel, alloy steel, casting, application
Material：VRA201/PRA11/HRF10/NRB10Z/MR11/PR40
