End Mills and Milling Cutters

Roughing Carbide Square End Mills

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds.

Fast-Cutting Carbide Square End Mills

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. They have a 90° corner for milling square corners in slots, pockets, and edges.

Fast-Cutting Carbide Square
End Mills with Chamfer Corner

A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them to provide fast cuts, smooth finishes, and long tool life.

Long-Reach Fast-Cutting Carbide
Square End Mills with Chamfer Corner

These end mills have an extended neck with a reduced diameter that prevents them from rubbing against your workpiece when deep milling. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials.

Long-Reach Fast-Cutting Carbide Square End Mills

These end mills have a neck that’s extended and has a reduced diameter—this prevents them from rubbing against your workpiece when deep milling.

Carbide Square End Mills for Carbon
Fiber, Fiberglass, and Graphite

A diamond or diamondlike coating on these end mills makes them good for machining abrasive material, such as carbon fiber, fiberglass, and graphite.

Carbide Square End Mills for Honeycomb Panels

Cut into the sides and make slots in honeycomb panels without damaging any layers.

Fast-Cutting Roughing Carbide Square
End Mills for Aluminum, Brass, and Bronze

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds without sacrificing tool life.

Long-Reach Roughing Carbide
Square End Mills with Chamfer Corner

These end mills have an extended neck with a reduced diameter that prevents them from rubbing against your workpiece when deep milling.

Roughing High-Speed Steel Square End Mills

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds.

Roughing Cobalt Steel Square End Mills

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds.

Roughing Cobalt Steel Square End
Mills for Aluminum, Brass, and Bronze

A higher helix angle means these end mills clear more chips than other roughing cobalt steel end mills, making them better for milling aluminum, brass, and bronze. Serrations along the cutting edge act as chip breakers, so they can remove large amounts of material at high speeds.

Carbide Ball End Mills for Carbon
Fiber, Fiberglass, and Graphite

These end mills have a diamond or diamondlike coating for machining abrasive material, such as carbon fiber, fiberglass, and graphite.

Fast-Cutting Carbide Ball End Mills

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material.

Long-Reach Fast-Cutting Carbide Ball End Mills

These end mills have either a neck or shank that’s extended and has a reduced diameter—this prevents them from rubbing against your workpiece when deep milling. Variable spacing between the flutes reduces vibration, allowing the end mills to provide fast cuts, smooth finishes, and long tool life on hard materials.

Roughing Cobalt Steel Ball End Mills

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds without sacrificing tool life.

Fly Cutters

Shave shallow layers of material off your workpiece to create a smooth even finish. These fly cutters hold a lathe tool and run on your milling machine.

Fast-Cutting Carbide Chamfer End Mills

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials.

Carbide Rounded-Edge Square End Mills
for Carbon Fiber, Fiberglass, and Graphite

A diamond coating on these end mills allows them to machine abrasive material, such as carbon fiber, fiberglass, and graphite.

Face Milling Cutters

With larger diameters than end mills, these cutters remove greater amounts of material to create a smooth, flat channel in the face of a plate, bar, or other wide workpiece.

Roughing Face Milling Cutters

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.

Replaceable Carbide-Insert Face Milling Cutter Kits

These kits include a cutter body, inserts, wrenches, and screws, so you can create your own face milling cutters, which are also known as indexable face milling cutters.

Replaceable Carbide-Insert Face Milling Cutters

Combine a cutter with carbide inserts to create a face milling cutter, also known as indexable face milling cutters.

Fly Cutter Sets

Keep a variety of fly cutters on hand to tackle different sized workpieces. The fly cutters in these sets hold a lathe tool (sold separately) to shave a layer off your workpiece with each pass, creating a smooth, even finish.

Replaceable Carbide-Insert Fly Cutters

These tools create a wide, shallow cut on the face of the workpiece. They're often used to level spoilboard so it lies perfectly flat for accurate routing and milling.
