Product Description

Q&A

A Square End Mill is a type of flat end mill, a tool used in industrial milling machines (like CNC machines). Its defining characteristic is that it has a 90-degree squared-off corner, creating a flat-bottomed groove or surface with sharp, clean inside corners when it cuts.

Hiboo Tools' HRC65° Square End Mills are engineered for superior performance in machining hardened steels, tool steels, and other difficult materials. Manufactured from premium micro-grain solid carbide, these end mills excel in high-speed applications while maintaining extreme wear resistance and thermal stability. The optimized flute geometry ensures efficient chip evacuation, reducing heat buildup and extending tool life. With advanced coatings (AlTiN/TiSiN optional) and rigid structural design, Square End Mills provide exceptional precision for mold making, aerospace components, and general precision machining.

Key Features of Square End Mills :

Flat Bottom: This allows for the creation of flat surfaces and square corners.

Straight Cutting Edges: These edges enable the mill to cut cleanly and efficiently through the material.

Various Sizes and Coatings: Square end mills come in different diameters, lengths, and with various coatings to enhance performance and tool life, such as TiN (Titanium Nitride) or TiAlN (Titanium Aluminum Nitride).

Square End Mill Applications:

Face Milling: Creating a flat surface on the workpiece.

Slot Milling: Cutting slots into the material.

Side Milling: Machining the sides of a workpiece.

Contour Milling: Machining complex shapes with flat surfaces and sharp corners.

Material Considerations:

High-Speed Steel (HSS): Good for general-purpose milling.

Carbide: Offers higher cutting speeds and longer tool life, suitable for harder materials.

Cobalt: Provides better wear resistance and toughness than HSS.
