Carbide Insert Chipbreaker - Finishing vs Roughing Insert | Cutoutil Tool

Professional Carbide Inserts for Precision Machining Solutions

Understanding Carbide Insert Chipbreaker: Finishing vs Roughing Applications

Carbide insert chipbreaker technology represents the pinnacle of cutting tool engineering, where precision meets performance. At Cutoutil Tool, we specialize in manufacturing high-performance carbide inserts with advanced chipbreaker geometries optimized for both finishing and roughing operations.

Key Differences Between Finishing and Roughing Chipbreaker Inserts:

Finishing Inserts:

Precision Geometry: Sharp cutting edges with smaller rake angles (5°-15°)

Chip Control: Narrow, shallow chipbreakers for controlled chip formation

Surface Quality: Optimized for Ra 0.4-1.6 μm surface finish

Cutting Parameters:

Cutting Speed: 200-400 m/min

Feed Rate: 0.1-0.3 mm/rev

Depth of Cut: 0.1-1.0 mm

Roughing Inserts:

Robust Design: Larger rake angles (15°-25°) for aggressive material removal

Chip Management: Wide, deep chipbreakers for heavy chip evacuation

Material Removal: High stock removal rates up to 6mm depth of cut

Cutting Parameters:

Cutting Speed: 100-250 m/min

Feed Rate: 0.3-0.8 mm/rev

Depth of Cut: 3-10 mm

Advanced Chipbreaker Design Features

Our carbide inserts incorporate cutting-edge chipbreaker geometries:

Variable Helix Chipbreakers: Reduce cutting forces by 15-25%

3D Optimized Rake Surfaces: Enhanced chip flow control

Micro-Textured Edge Preparation: Extended tool life by 30-40%

Multi-Functional Land Design: Suitable for various cutting conditions

For Finishing Operations:

Steel: Vc = 250-350 m/min, f = 0.1-0.2 mm/rev, ap = 0.1-0.5 mm

Stainless Steel: Vc = 180-280 m/min, f = 0.08-0.15 mm/rev, ap = 0.1-0.3 mm

Cast Iron: Vc = 200-300 m/min, f = 0.1-0.25 mm/rev, ap = 0.2-0.8 mm

For Roughing Operations:

Steel: Vc = 150-250 m/min, f = 0.3-0.6 mm/rev, ap = 3-6 mm

Stainless Steel: Vc = 120-200 m/min, f = 0.25-0.5 mm/rev, ap = 2-5 mm

Cast Iron: Vc = 180-280 m/min, f = 0.3-0.8 mm/rev, ap = 4-8 mm
