Description
CARBIDE TURNING INSERTS DCGT
DCGT carbide turning inserts are single-sided, positive-geometry inserts featuring a 55° diamond (rhomboid) shape with a 7°–11° relief (clearance) angle. Designed primarily for finishing and precision machining, DCGT inserts are widely used in turning operations on aluminum, non-ferrous metals, and stainless steels where sharp cutting edges and excellent surface finish are required.
Made from ultra-fine grain carbide (WC-Co) and often PVD coated (TiN, TiAlN, or uncoated for aluminum), DCGT inserts offer high sharpness, low cutting forces, and excellent chip control in light to medium-duty applications.

• Relief Angle: 7°–11° (positive geometry)
• Cutting Edges: Single-sided – 2 cutting edges per insert
• Mounting Type: Clamp or screw-on (usually with precision-ground insert seats)
• Coatings: PVD – TiN, TiAlN, TiCN, or uncoated (for non-ferrous materials)
• Application Type: Finishing, semi-finishing, light turning

Materials & Applications
DCGT carbide inserts are ideal for applications requiring fine surface finish, tight tolerances, and minimal cutting resistance. Their polished chipbreakers and sharp edges make them excellent for soft or gummy materials.
Typical Workpiece Materials:
• Aluminum & Non-Ferrous Alloys — exceptional performance with uncoated or polished-edge grades.
• Stainless Steel — good finishing results with sharp PVD-coated grades (TiN or TiAlN).
• Copper, Brass, Bronze — ideal for precision turning without built-up edge.
• Plastics & Composites — suitable for fine finishing with high edge sharpness.
Common Operations:
• Finishing and semi-finishing of precision parts
• Fine turning of aluminum and non-ferrous materials
• Light cutting and profiling
• Low-force applications on small or delicate components

Advantages & Performance
• High Surface Finish: Sharp, positive cutting edge ensures mirror-like finish and dimensional accuracy.
• Low Cutting Forces: Positive geometry and sharp edges reduce power consumption and heat.
• Excellent Chip Control: Special chipbreaker designs for aluminum and stainless steel reduce chip adhesion and improve flow.
• Edge Stability: Micro-grain carbide substrates enhance wear resistance even under high-speed cutting.
• Versatility: Available in multiple chipbreaker styles and grades for different non-ferrous and stainless materials.
