Single Flute Compression Router Bit - Up & Down Cut End Mill

Overview

This single flute up & down cut end mill is a compression-style spiral bit made from carbide for CNC routers and engraving machines. The main and auxiliary cutting edges work against each other, which helps keep the workpiece from tearing out or splintering while leaving a smooth, flat cut. Available in shank sizes from 3.175mm to 8mm.

Key Features

• Up & down cut geometry: opposing cutting forces from the main and auxiliary edges help prevent tear-out on the workpiece
• Mirror-ground, precision-polished blade stays sharp, resists chip sticking, and leaves a smooth, flat cutting surface
• Carbide construction is more heat-resistant and wear-resistant than other tool materials, and not easy to break
• Shank sizes of 3.175, 4, 5, 6, and 8mm fit common CNC and engraving machine collets
• Chamfered shank is easy to locate and helps prevent tilting during installation
• Cuts bamboo board, solid wood, MDF (density board), and particle board
• Supplied with a plastic protection case
