ALVAN® Reamer Cutting Ring Style

The cutting ring-style reamers are ideal for large diameter holes because they eliminate the need to replace a large solid reamer, reducing waste. The unique design allows for diameter expansion to accommodate for cutting edge wear. The cutting ring-style reamer can also be repaired to new condition which extends the life of the investment. ALVAN Reamers hold tight tolerances while improving the surface finish of the hole.

  • The cutting ring-style modular connection provides radial adjustment to improve runout
  • Multiple cutting edges which are set asymmetrically to guarantee almost perfect hole geometry
  • Expandable to maintain size tolerance which is particularly useful when repairing the cutting edges
  • Available with carbide, cermet, PCD or CBN cutting edges
  • Diameter Range of 0.6929 inch to 7.8975 inch (17.60 mm to 200.60 mm)
  • Straight or helical flutes for blind or through hole applications
  • Variety of edge geometries designed for multiple materials
  • Expands up to 4% on diameter
  • Modular or cylindrical shank
  • Radial coolant configuration
