We stock a wide variety of R-style carbide inserts from leading brands such as Korloy, Kennametal, Widia, Taegutec, Sandvik, Mitsubishi, and Iscar, ensuring you always find the perfect insert for your CNC machining needs.

What Are R (Round) Carbide Inserts?

R Inserts, also known as Round Inserts, are circular-shaped carbide inserts with 360° cutting edges. Unlike square, triangular, or diamond-shaped inserts, round inserts distribute cutting forces evenly, offering maximum toughness and resistance to edge chipping.

This makes them particularly effective in machining hard-to-cut materials, high-strength alloys, and cast iron, where tool wear is a major challenge.

Key Features of Round Carbide Inserts

• ✅ Extreme Edge Strength – Perfect for heavy roughing and interrupted cuts.

• ✅ Multi-Directional Cutting – Circular shape allows machining in multiple directions.

• ✅ Superior Heat Dissipation – Handles high cutting temperatures with ease.

• ✅ Extended Tool Life – Uniform edge wear improves insert longevity.

• ✅ High Feed Capability – Excellent for high-feed machining and profiling.

Applications of R (Round) Inserts

Round inserts are widely used in CNC turning, milling, and profiling across multiple industries:

• Heavy Roughing – Removes large material stock quickly.

• Interrupted Cuts – Handles uneven surfaces and casting skin effectively.

• High-Feed Milling – Suitable for aggressive machining strategies.

• Tough Materials – Excellent for machining Inconel, titanium, stainless steel, and hardened steels.

• Cast Iron & Forgings – Reliable performance on abrasive materials.

Types of R (Round) Carbide Inserts

Round inserts come in various grades, coatings, and edge geometries to suit different materials and cutting conditions:

1. Uncoated Round Inserts – For general-purpose cutting and non-ferrous materials.

2. CVD Coated Inserts – Ideal for steel and cast iron, providing wear resistance.

3. PVD Coated Inserts – Best for stainless steel, super alloys, and interrupted cutting.

4. High-Feed Round Inserts – Designed for aggressive machining at higher feeds.

5. Wiper Round Inserts – Delivers superior surface finish in finishing operations.
