Carbide-Tipped Reamer

Description

Top Ream platform finishes holes up to 42 mm in diam. Its range of edge preps and geometries available. TRF shank-style starts at 14 mm and the TRM modular tool from 20 mm.

Instead of four to eight (or more) individually brazed carbide tips, this reamer uses a single carbide disc and brazed joint to create a strong connection that
withstands the thermal effects during machining operations. Widia developed WU05PR advanced reaming grade specifically to hold up duruing the rigors of intense surface finishing applications.

Tests performed over a 30-m cut distance and maintained surface finishes of 32 μin Ra (0.8 μm) in 4140 steel alloy and 64 μin Ra (1.6 μm) in gray cast iron, three times that of TiAlN-coated tools.
