WBMT carbide insert

About WBMT carbide insert

WBMT carbide inserts are high-performance, rhombic-shaped (35-degree) indexable cutting tools designed primarily for precision turning, boring, and profiling operations on CNC lathes. They feature a positive rake angle, making them ideal for finishing and semi-finishing tasks requiring low cutting forces, excellent surface finishes, and high accuracy. [1, 2, 3, 4]

Key Characteristics and Features

• Geometry: WBMT inserts are diamond-shaped (trigon/rhombic) with a 35 corner angle, often designated by the "W" in the ISO code.
• Cutting Edge: They feature a 5-degree positive flank/relief angle (denoted by the "B"), which helps reduce friction and heat generation, particularly in delicate or high-precision operations.
• Versatility: Suitable for both external turning and internal boring applications, including profile machining, back boring, and undercutting.
• Chipbreakers: Designed with specialized chipbreakers (such as DP, VP, or EF) that ensure effective chip control in both finishing and semi-finishing operations. [1, 2, 5, 6, 7]

Common Applications and Materials

WBMT inserts are frequently used for machining hard-to-cut materials requiring high durability and precision.

• Materials: Excellent for steel, alloy steel, stainless steel, and ductile/nodular cast iron.
• Finishing & Semi-Finishing: Ideal for finishing operations where superior surface finish is critical.
• Industrial Applications: Widely applied in automotive, aerospace, and general precision engineering. [2, 9, 10]

Material Composition and Coatings

• Cermet/Carbide Grade: Often manufactured from advanced cermet (ceramic + metal) or tungsten carbide grades.
• Coatings: Commonly coated with PVD (Physical Vapor Deposition) or CVD (Chemical Vapor Deposition) techniques, such as TiCN + Al2O3, to improve wear resistance and extend tool life, especially at high speeds.
• Example Grade: Kyocera TN60 is a common cermet grade used for high-efficiency finishing. [2, 8, 11]

WBMT Insert Designation Examples

• WBMT 060104: The represents the inscribed circle (roughly 6.35 mm), is the thickness, and represents a 0.4 mm corner radius.
• WBMT 080204: A larger insert with 0.8 mm (or 0.4 depending on suffix) corner radius, suited for deeper cuts. [6, 8, 12]

Typical Performance Benefits

• Low Cutting Forces: Due to positive geometry, reducing vibration in slender components.
• Long Tool Life: Excellent resistance to plastic deformation and wear.
• Surface Finish: Delivers high-quality, smooth finishes, reducing the need for grinding. [2, 9, 13]

Common manufacturers of WBMT inserts include Kyocera, Iscar, and TaeguTec. [5, 11, 14]

Industrial-Grade Durability

Engineered for high-demand environments, the WBMT carbide insert boasts impressive hardness (HRA 89-92) and superior tensile strength. Its PVD-coated tungsten carbide construction offers excellent corrosion and wear resistance, ensuring reliable performance and reduced downtime even in the toughest machining operations.


Extended Tool Life and Precision

Featuring a 3.5 mm thickness and a polished finish, this insert provides precise cutting with a tolerance of 0.05 mm. The double-sided design enhances cost-efficiency, while its high max feed rate (0.30 mm/rev) and speed (250 m/min) enable efficient material removal, lowering production costs in professional setups.


Versatile Compatibility and Application

The WBMT insert fits most indexable tool holders and supports both right and left-hand cutting, offering flexibility across machining centers. Its rectangular/custom WBMT profile makes it suitable for turning, boring, and general metal cutting, catering to manufacturers, exporters, and suppliers in diverse industries.
