Seco Tools R220.49-01.50 Milling Cutter

Seco Tools R220.49-01.50 Milling Cutter is a 1.5-inch diameter indexable chamfer mill designed for precise 45-degree chamfers in the feed direction. Catalog number 00070079, this arbor-shank cutter features an overall length of 1.57 inches and a 0.75-inch arbor hole, making it compatible with standard Seco tooling systems. It supports a maximum depth of cut of 0.276 inches per pass, enabling controlled chamfering on edges, shoulders, or lead-ins. The cutting edge is set at a 45° angle in the feed direction, optimizing chip formation for efficient material removal during chamfer passes. An observed variant with a C-Lock shank (R22049-0150) expands mounting options for compatible holders. Typical applications include chamfer milling and edge preparation on metal workpieces, deburring corners, and preparing precise entry surfaces for mating parts. When selecting this cutter, verify that your holder and arbor specifications match the 1.5-inch cutting diameter and the 0.75-inch arbor hole to achieve the intended geometry and depth-of-cut limits.
