TiAlN coated Ultra-Kut™ annular cutters are the ultimate in cutting performance. These cutters are designed specifically for situations where cutting fluid is impractical or not permitted.
Titanium Series Annular Cutters feature multi-layered coating – reducing heat from cutting friction, lowering friction and improving service life by 3-4x over regular annular cutters. This increases productivity through less downtime and substantially reduces costs.
Annular cutters are great for making new holes – but they are lousy at makes holes larger. Attempting to enlarge a hole is the primary cause of cutter breakage. To enlarge a hole, use a reamer or lathe.
