WIDIA WCMT050308 PA120
Push your turning operations further with the WIDIA WCMT050308 PA120: a PVD-coated carbide insert that delivers higher wear resistance, excellent surface finish, and reduced cost per component when machining steel. From light to medium cutting depths, this insert keeps you running longer with fewer tool changes.
WIDIA WCMT050308 PA120 is a premium carbide turning/drilling insert designed for demanding machining environments, especially steel workpieces. Made by WIDIA, it features:
Key Features
-
Grade: PA120 – a high performance carbide grade with PVD coating (TiAlN) that enhances hardness, heat resistance, and wear protection.
-
Geometry / Insert Type: WCMT050308 – standard WCMT format. Suitable for positive chipbreaker/trigon-style turning or drilling depending on tool holder. (WCMT = “W-trigon” shape, which gives robust edge strength with decent clearance.)
-
Material: Fully carbide substrate, PVD coated. Designed for steel, also usable in some stainless steel and high-temperature applications depending on cutting conditions.
-
Coating: TiAlN PVD – fights heat, resists wear, reduces adhesion, improves edge life.
-
Typical Uses / Cutting Applications:
• Turning operations (general to medium) on steel workpieces.
• Drilling inserts / indexable drills where this insert form is used.
• Light- to medium depth of cut, moderate feed rates to take advantage of wear resistance without overloading edge.
Why It’s a Best-Seller
Why It’s a Best-Seller
-
Longer tool life & less downtime: The PA120 grade plus PVD coating means you change inserts less often, saving machine idle time and reducing tooling costs.
-
Better surface finish: The carbide + coating helps maintain sharpness and reduces build-up, giving cleaner surface finish especially when dealing with steels.
-
High wear resistance: Especially under tougher steel cutting conditions (higher speed, moderate feed), this insert resists flank and crater wear, extending usable life.
-
Reliable performance across batch sizes: Whether you’re doing single parts or high volume runs, the consistency of the insert (shape, material, coating) ensures repeatable results.

Frequently Asked Questions
It excels with steels (both low- and alloy steels), especially in operations with moderate speeds and feeds. It can also handle some stainless steels, though cutting parameters must be optimized (lower speed, high coolant, etc.).
Yes — the TiAlN coating and carbide grade give strong performance even under intermittent or roughing cuts, though care must be taken not to overload the edge (excessive depth of cut or feed beyond its capability).
WCMT is a trigon/“W-trigon” style insert (80° trigon shape), usually positive or neutral rake depending on the chipbreaker. Its strengths are edge strength and versatility. Limitations: if you need ultra-fine finishing, very light cuts, or extremely abrasive materials, other geometries or grades might be more suitable.
While exact numbers depend on your setup, many users see 30-50% longer life per insert, and when factoring in reduced downtime and scrap, overall cost per component can drop significantly.
