Also known as involute gear cutters, these tools work with a milling machine to create 14½° or 20° pressure angle spur gears. If worn, they can be sharpened and used again.

To select a gear cutter, follow these steps:

1. Determine the pitch of the gear you're cutting. Gear pitch = (No. of Teeth + 2) / OD. Round to the nearest whole number.

2. Select the cutter that matches your gear's pitch and number of teeth.

Use these end mills for general purpose work in most material, such as aluminum, brass, bronze, iron, and steel. The teeth are angled in two directions so you can make top and bottom chamfers without having to flip the workpiece.

Use these versatile end mills for milling in most material, including aluminum, brass, bronze, iron, and steel. They have scooped corners for rounding the sharp edges of your workpiece.

Serrations along the cutting edge act as chip breakers, so these cutters can remove large amounts of material at high speeds without sacrificing tool life. With larger diameters than end mills, they remove greater amounts of material to create a smooth, flat channel in the face of a plate, bar, or other wide workpiece. Compared to fly cutters, they’re more rigid, which makes for a better finish. Also known as shell cutters. With better heat and wear resistance than high-speed steel, these cobalt steel cutters can run at higher speeds and provide better performance on hard material, such as hardened steel, iron, and titanium.

Mill an angled edge to the entire outside diameter of pipe, tubes, and rods in a single pass with more speed and precision than a handheld scraper. These end mills deburr pipe and tube for butt welds and shape rods for sliding into housings and holes. They attach to screw machines, lathes, and drill presses and can be set up to repeat cuts for multiple pipes. Staggered cutting edges reduce vibration, resulting in a smooth finish. They have teeth that distribute cutting force and extend the life of the tool. Made of high-speed steel, they work with a variety of metals.
