Our 1-1/8″ One-Piece Carbide Cutters feature carbide teeth for longer life and smooth cuts in stainless steel and other hard metals. Each cutter features a stop-shoulder design that prevents over-drilling and limits cuts to a 3/16″ depth, while a 3-flat shank optimizes each cutter drill bit for use in Drill/Drivers. The spring-loaded pilot bit provides complete plug ejection for clean, efficient cutting of each hole. The solid one-piece design of each hole cutter provides you with added durability and dependability cut after cut. MILWAUKEE One-Piece Carbide Cutters are available in sizes ranging from 3/4″ – 4-1/2″.
