Allied Machine 152T-1.1718 Spade Drilling Insert

152T-1.1718 is a TiN-coated spade drill insert for Allied Machine’s T-A Replaceable Insert Drilling System, with a 1.1718-inch diameter. It belongs to the 152T series and is designed to pair with compatible T-A spade drill holders to convert a drill body into a replaceable-insert drilling tool. The TiN coating provides a hard surface for metalworking drilling and helps maintain edge geometry through multiple uses. This insert size is selected to achieve the specified hole diameter when used with the corresponding spade drill body and seating arrangement in Allied’s T-A lineup. The T-A system uses replaceable inserts so users can swap worn edges quickly, minimizing downtime and tooling waste without changing the entire drill assembly. For proper operation, confirm that your spade drill holder accepts 152T inserts and that the 1.1718-inch diameter matches the required hole size in your project, material, and feed parameters.
