Adafruit Carbide Square End Mill - 1/8" Shaft - 0.7mm Diameter

Transform your PCB designs into reality with our precision CNC end mills, originally ordered for use with an Othermill. These versatile tools are compatible with a variety of CNC machines, enabling precise circuit board routing by cutting away copper trace outlines.

Unlike traditional drill bits, which only move in an axial direction, these end mills offer multi-directional cutting capabilities—side to side, up and down, and more. Crafted from tungsten carbide, they deliver exceptional hardness, wear resistance, and sharpness.

Our end mill features an 8mm flute length, allowing for effective cutting through PCBs and even some soft metals. Though the flutes are longer than standard, they maintain low replacement costs, making them economical when dulled. Typically, each bit lasts around 5 hours of cutting time before needing a swap.

This package includes a single 0.7mm carbide end mill, conveniently stored in a protective plastic case for durability and ease of use. Ideal for precision circuit board fabrication and beyond.
