2inch Face Milling Cutter with MT3 Arbor

2inch Face Milling Cutter with MT3 Arbor: Face Milling Cutters are also known as indexable face milling cutters. They Combine a cutter with carbide inserts (sold separately) to create a face milling cutter. They remove metal at least two times faster than comparable high-speed steel face milling cutters. When the cutting edges dull replace the carbide inserts instead of the entire tool. They are used together with an MT3 shank arbors which are sold separately.

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. Titanium-carbonitride (TiCN) coated inserts have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Titanium-aluminum-nitride (TiAlN) coated inserts dissipate heat better than other inserts, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the inserts cool, even when used without lubrication.

Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts. Use round inserts for roughing and heavy cuts. Their shape makes them stronger than octagon and square inserts. Use square inserts to create a 90° corner when shoulder milling.
