Features A 1/8 inch cutting edge and a standard 1/8 inch shank diameter would fit many CNC milling machines or cutting machines. This end mill set is made from high quality tungsten carbide for good hardness and the cutting edge is quite sharp. Usually these end mills are used to cut acrylic, PVC, MDF, density board, wood and many other soft materials. There are total 10 end mills in this set that would be a great replacement. A single-flute end mill with cutting edge would provide a smooth cutting surface and chip clearance. Description: This is a set of single flute end mill cutting tools used in industrial milling applications. It differs from the drill bit in its application, geometry and manufacture. Single-tooth end mills are used for better chip evacuation during high-speed milling. These cutters are made of tungsten carbide which will tolerate much more heat while maintaining good hardness. Features: Material: tungsten carbide. Cutting edge diameter: 3.17 mm (1/8") Flute: 1 Shank diameter: 3.17 mm (1/8") Cutting edge length: 17 mm (0.67 inches). Total length: approx. 38 mm (1.49 inches) Cuts on: Acrylic, PVC, MDF, Density Board, Wood, etc. Quantity: 10 pieces Package includes: 10 x End Mills Package List
