Product Introduction

 

Square-end milling cutters, also referred to as flat-end milling cutters, boast razor-sharp corners, creating a perfect 90° angle. These versatile cutters can come in single or double-end designs, with the choice of constructing them from solid carbide or diverse compositions of high-speed steel. Among the array of flat-end milling cutters, the most efficient ones are the flat micro-diameter milling cutters. These cutters can be categorized as either general-purpose or high-performance, catering to a wide range of milling needs such as plunging, grooving, side milling, face milling, and counter boring. Due to their immense popularity in the industry, they are available in a plethora of diameter sizes, ensuring suitability for various applications.

 

Flat Micro-diameter Milling Cutters with two flutes are ideal for roughing operations and cutting 2D shapes, including engravings and circuit boards. These carbide end mills are also used for cutting flat-sided 3D shapes, and can be utilized to create a square edge on materials such as metal, wood, wax, and plastic.
This type of milling cutter is commonly used in industrial milling applications and differs from a drill bit in both its application and design. A drill bit can only cut in the axial direction, whereas most milling bits have the ability to cut in the radial direction. Some mills are specifically designed to cut axially and are called milling cutters.
Milling cutters serve various purposes in milling applications, including profile milling, tracer milling, face milling, and plunging. They can also be categorized by their coating, which includes options like uncoated, AlTiN, TiSiN, AlTiSiN, DLC coating, diamond coating end mills, and more.

 

Our customers absolutely love our 2 Flutes Flat Micro-diameter Milling Cutter - it's the most requested end mill in our inventory. What sets it apart is its unique flute design - fewer flutes means smoother chip removal, while more flutes provide more precise processing. It's an essential tool for groove processing, side processing, and step surface processing.
