Material Type: Filter by primary workpiece material to find the inserts that are best suited for that specific material. You can also then filter by secondary workpiece material to find inserts that will cut multiple materials.

There are four main types of free machining steel: leaded, resulfurized, rephosphorized and super. Super free-machining steels are alloyed with tellurium, selenium, and bismuth.[3]

Indexable inserts

Free machining steels are carbon steels that have sulfur, lead, bismuth, selenium, tellurium, or phosphorus added. Sulfur forms the compound manganese sulfide, which is soft and acts as a chip-breaking discontinuity. It also acts as a dry lubricant to prevent a built up edge on the cutting tool. Lead works in a similar way to sulfur. Bismuth achieves a free machining steel by melting into a thin film of liquid for a fraction of a microsecond to lubricate the cut. Other advantages to bismuth include: more uniformly distributed because of its similar density to iron; more environmentally friendly, as compared to lead; still weldable.[1]

Milling Cutter Series: Filter by the Haas Milling Cutter Series to find all the inserts available for that specific cutter. If you don’t know the cutter series (or have a non-Haas cutter body), you can also filter by insert style (shape), or ANSI designation.

90° cutting edge | D.O.C. max. 0.63" (16.0mm) • Positive axial rake, negative radial rake • 3D helical cutting edge for lower cutting forces • Wiper geometry for high-quality surface finishes • Superior perpendicularity and minimized cutting loads

Free machining steel is steel that forms small chips when machined. This increases the machinability of the material by breaking the chips into small pieces, thus avoiding entanglement in the machinery. This enables automatic equipment to run without human interaction. Free machining steel with lead also allow for higher machining rates. Free machining steel costs 15 to 20% more than standard steel, but this higher cost is offset by increased machining speeds, larger cuts, and longer tool life.[1]

There are several variables that go into choosing the correct insert for your milling operations: the specific cutter body being used (milling cutter series), the type of machining operation (toolpath type), the cutting-edge angle (lead angle), the depth of cut, the materials being cut, and more. Use the filters on the left-hand side below to narrow down your choices, and find the inserts you need.
