Carbide Inserts for Replaceable Carbide-Insert Milling Cutters


	Octagon	Round	Square

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.

Titanium Carbon Nitride (TiCN)-Coated Carbide—Titanium-carbon-nitride (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 Carbide—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.

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.

Pair these carbide inserts with insert holders to mill the surface of plates and bars. They have a negative rake, so they have cutting edges on both sides—they last longer than comparable positive-rake inserts. As each edge dulls, you can rotate to a fresh one. When all the edges on one side are worn, flip the insert over. Built-in chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.

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.

Holders for Replaceable Carbide-Insert Face Milling Cutters

Designed for milling the surfaces of plates and bars, 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. Cutters have a large mill diameter for making wide, shallow cuts on the face or side of your workpiece. They also have a hole that passes coolant from your machine onto the workpiece, minimizing heat.

When choosing a holder, consider the grit rating you want. The finer the grit, the more inserts you’ll need. More inserts mean tighter spacing, so you can machine at high speeds and remove material quickly while leaving a smooth surface. However, you’ll also need more machine power.

Inserts (Sold Separately)

Coarse Grit—Fewer inserts mean a coarser grit—the inserts are spaced apart to help with chip evacuation. A coarse grit is best for roughing applications, light machining, and cutting soft metals such as aluminum.

Inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine. They have a negative rake, which means they have cutting edges on both sides. They last longer than comparable positive-rake inserts. As each edge dulls, you can rotate to a fresh one. When all the edges on one side are worn, flip the insert over. Built-in chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.

Designed to reduce waste and costs during high-volume jobs, these counterbores consist of both an insert and a holder. When the cutting edges dull, you can replace the insert rather than the entire tool. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine. These counterbores create flat-bottomed holes that allow socket head screws to sit flush with the surface of your material.

Carbide Inserts


Individual Carbide Insert Case

Inserts have a positive rake, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For longer life, each insert has three cutting edges—when one edge dulls, rotate to the next one. They have chip breakers to stop long chips from forming, so they won’t block the flow of coolant or damage your tool. 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.
