Dorian Tool 73310165249 Indexable Dovetail Cutter 3 in

Product Description

The DORIAN TOOL 73310165249 is an indexable dovetail cutter designed for machining dovetail slots and angled undercut features on milling machines and machining centers. Built with a 60-degree included angle and a 3-inch maximum cutting diameter, this cutter accepts three TDEX 220408-EN style inserts for repeatable, high-productivity cutting. The 1-inch straight shank provides rigid toolholder engagement, and the 3.5-inch overall length suits standard vertical and horizontal milling setups. Machinists and toolroom professionals install this cutter when production dovetail profiles are required with indexable insert economy.

This dovetail cutter is suited for ferrous and non-ferrous workpiece materials in job shop and production environments. The TDEX insert style with a 220408-EN size code is a common indexable format stocked by major insert suppliers. The 15-degree rake angle combined with a 10-degree axial rake and 14-degree radial rake promotes efficient chip evacuation in dovetail slot applications. Typical use cases include fixture plate dovetail slots, machine way dovetailing, and production part undercut milling on CNC or manual knee mills.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the 1-inch shank in a properly sized end mill holder or collet chuck and verify runout before cutting. Power down and lock out the spindle before seating or indexing inserts. Follow the machine tool manufacturer and cutting tool supplier recommendations for spindle speed and feed rate based on workpiece material and depth of cut.
