Fast-Cut Carbide Barrel End Mills for Aluminum, Brass, and Bronze

3 Flutes |
 |
4 Flutes |
A titanium diboride (TiB2) coating reduces friction when working with nonferrous metals, so you can use these end mills to cut soft metals like aluminum, brass, and bronze. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. Also known as barrel cutters, these end mills create the smooth finish of a ball end mill, but with a tapered cutting surface that removes more material with each pass. They're ideal for 5-axis machining where you need to cut from many angles. Plus, compared to ball end mills, they move farther between overlapping passes (stepover), which decreases machining time and tool wear, so they’ll last longer. All are center cutting, allowing plunge cuts into a surface.
Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking.
3 Flutes—End mills with three flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.
4 Flutes—End mills with four flutes provide a finer finish and operate with less vibration when run at high speeds.

Carbide Inserts for Replaceable Carbide-Insert Milling Cutters

Combine a holder with carbide inserts to create a milling cutter, also known as indexable milling cutters. They remove metal at least two times faster than comparable high-speed steel milling cutters. When the cutting edges dull, replace the carbide inserts instead of the entire tool.
Use with an R8 shank arbor (sold separately).
Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.
Titanium Diboride (TiB2)-Coated Carbide—Titanium-diboride (TiB2) coated inserts reduce friction in nonferrous metals and composites, so you can use them without lubrication in material like aluminum, fiberglass, and plastic.
Octagon—Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts.
Round—Use round inserts for roughing and heavy cuts. Their shape makes them stronger than octagon and square inserts.
Square—Use square inserts to create a 90° corner when shoulder milling.

Coated inserts are best for demanding, high-speed jobs and hard materials. They’re harder and more wear resistant than uncoated carbide inserts.
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.
Choose inserts with a smaller tip radius to reduce vibration and create smaller chips, so chip evacuation is easier. Choose inserts with a larger tip radius for more aggressive machining—they have a stronger cutting edge, so they remove more material with each pass.
Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.
Use uncoated inserts for general purpose milling and short production runs.
Negative Rake Angle—Negative-rake angle inserts have cutting edges on both sides, so they last longer than positive-rake inserts. When all the edges on one side are dull, flip the insert over.
