1. Advantages of Carbide Inserts

The LOGU0303 milling insert is manufactured from cemented carbide, a composite material made by combining tungsten carbide particles with a cobalt or nickel binder. Compared to conventional high-speed steel (HSS), carbide inserts offer multiple advantages:

Superior Hardness

Carbide hardness exceeds 90 HRA, enabling it to withstand high cutting forces and abrasive wear.

Heat Resistance

Carbide maintains structural integrity at temperatures up to 1000°C, allowing for high-speed machining.

Extended Tool Life

Increased wear resistance reduces tool change frequency, lowering operational costs.

High-Speed Cutting

Enables faster material removal rates, increasing production efficiency.

Excellent Surface Finish

Maintains cutting edge sharpness, resulting in smooth, precise surfaces.

These material advantages make LOGU0303 inserts an essential choice for industries where durability and precision are non-negotiable.

2. Decoding the LOGU0303 Insert Code

Every insert code follows ISO standards to describe its geometry and size. The breakdown of LOGU0303 is as follows:

L – Insert shape: 90° parallelogram/rectangular profile, common in milling operations.

O – Relief angle: Typically 11° or positive geometry for reduced cutting forces.

G – Tolerance class: Medium-to-high precision, balancing accuracy and cost-efficiency.

U – Insert type: Single-sided insert with optimized chip breaker design.

03 – Insert length: Approx. 3.0 mm.

03 – Insert thickness: Approx. 3.0 mm.

Thus, LOGU0303 defines a compact carbide insert optimized for stability, chip control, and efficient cutting in square shoulder and general milling applications.

3. Performance Benefits of LOGU0303
