3" End Mills | McMaster-Carr

Use these tools with low-horsepower, manual milling machines. They have clamps for holding inserts that do not have a mounting hole. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire end mill.

Replaceable Carbide-Insert Square End Mills

Pair carbide inserts with a holder to create end mills that reduce waste and cost in high-volume jobs. When the cutting edges dull, replace the inserts instead of the entire tool.

Carbide Inserts for Replaceable
Carbide-Insert Square End Mills

Pair these carbide inserts with a holder to create end mills that reduce waste and cost in high-volume jobs. When all the cutting edges dull, replace the inserts instead of the entire tool.

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.

Milling Cutters

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 Milling Cutters

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

Replaceable Carbide-Insert Milling Cutter Kits

Create your own versatile milling cutters. These kits include a cutter body, inserts, wrenches, and screws.

High-Speed Steel Slitting Saws

These general purpose saws are good for cutoff, slitting, and slotting applications in a wide range of materials, including aluminum, iron, and steel.

Carbide Slitting Saws

Made of solid carbide, these saws are harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Use them for cutoff, slitting, and slotting applications.

Smooth-Finish Slitting Saws

Also known as jeweler's slotting saws and metal slitting saws, these saws are good for use on wire, tubing, extrusions, and other very thin material that requires delicate cuts.

Slitting Saws with Side Teeth

With peripheral and side teeth, these saws remove chips for a consistent cutting width.

Replaceable Carbide-Insert Face Milling Cutters

Designed for milling the surfaces of plates and bars, these cutters consist of multiple carbide inserts and a holder. They help you reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the inserts instead of the entire tool.
