KENNAMETAL WNMG0804FP KC5010 Turning Inserts – Finishing & Medium Cutting for Steel
KENNAMETAL Carbide Inserts for Industrial CNC Machining
Kennametal Inc. (NYSE: KMT) is an 88-year-old American manufacturer of tungsten carbide tooling, headquartered in Pennsylvania, USA. Founded in 1938 as a specialty tungsten carbide producer, Kennametal has grown into one of the four global carbide tooling majors alongside Sandvik, Walter, and Mitsubishi. Our Kennametal collection currently stocks KC5010 turning inserts for steel finishing, with five additional KC-series grades available on-demand — KC7315, KC7325, KCK20, KCS10, KCP25 — covering the full range of ISO P, M, K, and N workpieces. Same-day shipping to 50+ countries via DHL / UPS / FedEx.
Why Choose Kennametal Inserts for CNC Machining
Kennametal's reputation in the global carbide market rests on four differentiators that matter most to aerospace, automotive, and high-mix manufacturers:
KC™ Grade Naming System
Kennametal invented the four-digit numerical grade nomenclature used industry-wide (KC5010, KC7315, etc.). The KC prefix + 4 digits tells you the ISO material class, coating chemistry, and tool-life expectation at a glance — no deciphering needed.
88 Years of US Manufacturing
Kennametal has produced tungsten carbide tooling continuously from its Latrobe, Pennsylvania headquarters since 1938. The company also operates engineering centers in Germany, India, and China, but the core R&D and grade chemistry work is anchored in Pennsylvania.
NYSE-Listed Public Accountability
As a NYSE-listed company (ticker: KMT), Kennametal publishes quarterly financials and is subject to SEC reporting. For B2B buyers in aerospace and defense, public-company transparency is a procurement criterion that private competitors cannot match.
Aerospace & Defense Specialization
Kennametal's Beyond™ product line and Stellite cobalt-chrome alloys are specified by Boeing, Airbus, Lockheed Martin, and Pratt & Whitney for high-temperature superalloy machining. Aerospace-grade inserts follow AS9100 / Nadcap certification — Kennametal's standard, not an upcharge.
Kennametal KC™ Grade Naming System
The KC prefix + 4 digits is a structured nomenclature where every position encodes a specific attribute. Understanding the system makes it possible to identify the right grade without consulting a catalog.
| Position | Encoded Information | Example (KC5010) |
|---|---|---|
| KC prefix | Kennametal Carbide (registered trademark) | KC |
| 1st digit | Coating family — 5 = PVD TiAlN family (steel / stainless finishing) | 5 (PVD TiAlN) |
| 2nd digit | Application range within coating family — 0 = finishing (sharp edge), 3 = medium, 5 = roughing | 0 (finishing) |
| 3rd digit | Substrate classification — 1 = submicron carbide, 5 = medium grain, 9 = coarse grain | 1 (submicron substrate) |
| 4th digit | Generation — 0 = current generation, prior generations retired | 0 (current) |
Examples of decoded KC grades: KC5010 = PVD TiAlN + finishing + submicron + current (ISO P05–P15). KC7315 = CVD TiCN/Al2O3 + medium + submicron + current (ISO P15–P25). KC7325 = CVD + medium + medium grain (ISO P20–P30). For complete grade decoding across all 8 brands, see our Grade Cross-Reference Hub.
Kennametal Live Stock & On-Demand Grades
The Kennametal collection maintains one core grade in stock for same-day shipping (KC5010) plus five on-demand grades (7-14 business days from Pennsylvania factory or EU distribution centers).

| WNMG080408 KCK20 | KCK20 (CVD multi-layer) | ON-DEMAND | P20–P35 | Steel general-purpose turning — balanced wear and toughness |
| CNMG120408 KCS10 | KCS10 (PVD TiAlN) | ON-DEMAND | M10–M25 | Stainless steel finishing to medium — sharp edge with low BFE risk |
| SNMG120408 KCP25 | KCP25 (CVD TiCN/Al2O3) | ON-DEMAND | P25–P40 | Steel roughing — heavy edge with reinforced chipformer |

Frequently Asked Questions
What does the KC prefix mean in Kennametal grade names?
KC is a registered Kennametal trademark standing for "Kennametal Carbide." It is followed by four digits that encode the coating family, application range, substrate classification, and generation. For example, KC5010 = PVD TiAlN coating family (5), finishing range (0), submicron substrate (1), current generation (0). KC7315 = CVD coating family (7), medium range (3), submicron substrate (1), current generation (5). For complete grade decoding, see our Grade Cross-Reference Hub.
What is the difference between Kennametal KC5010 and KC7315?
KC5010 is a PVD (Physical Vapor Deposition) TiAlN-coated grade for steel and stainless finishing, with a sharp honed edge to minimize built-up edge in low-Vc finishing passes. KC7315 is a CVD (Chemical Vapor Deposition) TiCN + Al2O3 coated grade for steel medium turning, with a thicker Al2O3 layer for thermal stability at higher Vc. In short: KC5010 for finishing (PVD sharp edge); KC7315 for medium (CVD wear resistance).
Is Kennametal KC7315 a direct equivalent to Sandvik GC4325?
Yes. Kennametal KC7315 is the closest drop-in equivalent to Sandvik GC4325 and Walter WKP25S in ISO P15-P25 steel turning applications. Both have a CVD coating stack and target medium-duty steel machining. For the full 8-brand cross-reference matrix, see our Grade Cross-Reference Hub.
What is the Beyond™ product line for aerospace and superalloy machining?
Kennametal Beyond™ is a specialty product family launched in 2015 for aerospace and defense applications, including Inconel 718, titanium (Ti-6Al-4V), Waspaloy, and Rene 65. Beyond™ inserts use a third-generation CVD aluminum-oxide coating plus a cobalt-enriched substrate for thermal shock resistance at Vc 50-80 m/min. The line is AS9100 / Nadcap certified and specified by Boeing, Airbus, and Pratt & Whitney for engine component machining.
Can Kennametal KC5010 inserts be used on Swiss-type lathes?
Yes, with caveats. Kennametal KC5010 inserts in WNMG0804FP geometry fit any holder that accepts the corresponding ISO WNMG 08 geometry. For Swiss-type lathes, the constraint is holder OD: most Swiss lathes accept 12-16 mm shank boring bars, so use a compatible S...-WNMG holder in the 12 mm shank class. The sharp honed edge of KC5010 is well suited to the small-diameter, high-spindle-speed regime typical of Swiss turning (Vc 150-200 m/min, fz 0.05-0.10 mm/rev).
What is the lead time for Kennametal inserts to the US or EU?
The live Kennametal KC5010 (WNMG0804FP, 10 pcs per box) ships same-day from our Hong Kong warehouse with DHL Express to US / EU destinations in 3-7 business days. The five on-demand grades (KC7315, KC7325, KCK20, KCS10, KCP25) ship from Kennametal's Pennsylvania factory or EU distribution center in 7-14 business days, with full Certificate of Conformance and AS9100 / ISO 9001 documentation.
