Kennametal KC730 KC730 – Grooving/Parting Carbide Insert

The Kennametal KC730 grooving insert excels in general milling applications on steel workpieces, leveraging its tin-coated KC730 grade carbide to minimize wear and optimize chip formation. With a 3.61 mm cutting width and 3.81 mm maximum depth, this insert is well-suited for a range of parting and grooving operations, particularly those requiring precise control and a smooth finish. Whether you’re working with low-carbon, medium-carbon, or high-carbon steel, the KC730 insert’s tin coating helps to reduce friction and prevent built-up edge, ensuring consistent results and extended tool life.

Grade KC730 Characteristics

Kennametal KC730 uses tin coating tuned for general milling on steel. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Kennametal – Original product with full quality guarantee, traceable batch.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Milling of steel in production CNC lines
Useful for batch production where tool-life predictability matters
Performs across a range of cutting speeds and feed rates
Suitable for both wet and dry machining conditions

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Entry-tier pricing makes this a low-risk option for trialing Kennametal tooling on a new material.

Note: Compatible tool holders sold separately. Please confirm insert-holder seat compatibility (e.g. ISO seat designation) before ordering.
