Diamond-shaped insert made of K10 carbide – applications and design
positive 80° diamond with a sharp, polished cutting edge for nonferrous metals
The CCGT 060204 turning insert is a diamond-shaped indexable insert made of grade K10 fine-grained carbide, designed for turning aluminum and other nonferrous metals. Shape C, a diamond with a 80° corner angle, combines a strong corner with good contour access during longitudinal turning and facing. The positive geometry with a 7° clearance angle reduces cutting forces and produces a thin, continuous chip. The insert is single-sided with two usable corners, and its sharp, polished cutting edge (GT designation) reduces built-up edge on ductile materials.
Key benefits of the K10 carbide insert
- Sharp, polished GT cutting edge — positive rake and a smooth rake face reduce built-up edge and chip groove clogging when turning aluminum.
- Grade K10 for ISO group N — fine-grained carbide for aluminum, copper alloys, and brass; maintains cutting edge sharpness at high speeds.
- Corner radius rε 0.4 mm — a balance between low surface roughness and edge strength at feed rates of 0.1–0.2 mm/rev.
- The 7° clearance angle allows operation without a positive shim and reduces friction on the machined surface.
- Dimensions according to ISO 1832: edge length 6 mm, IC 6.35 mm (1/4″), thickness 2.38 mm — fit holders with a 06 pocket.
- The 80° corner angle provides a rigid corner for longitudinal turning, facing, and light copy turning in a single setup.
Applications and cutting data selection for the diamond-shaped insert
The CCGT 060204 insert (also written without spaces as ccgt060204) is suitable for turning bushings, pistons, flanges, and thin-walled components made of aluminum, copper alloys, and brass. The sharp cutting edge and positive rake minimize workpiece deformation and prevent ductile material from clogging the chip groove. Calculate spindle speed using the formula n = 1000·Vc/(π·D): for a shaft diameter of 50 mm at a cutting speed Vc = 600 m/min, the result is approximately 3820 rpm. Aluminum allows high cutting speeds — for finishing, the manufacturer specifies a range up to 2400 m/min at a feed rate of 0.1 mm/rev. Grade K10 indexable inserts are supplied by the Korean brand Horn.
For finishing, the best results are achieved with a shallow depth of cut of approximately 0.1–0.5 mm and a feed rate of 0.1 mm/rev, which maintain low surface roughness without burrs. For roughing, the insert accepts depths of cut up to 3 mm and a feed rate of 0.2 mm/rev; however, radial forces should be limited on thin-walled workpieces to prevent wall deformation. A constant, generous supply of emulsion or oil coolant removes small, sticky aluminum chips from the cutting zone and protects the polished rake face. A central screw clamps the insert into the holder pocket, providing repeatable cutting edge positioning after indexing to the second corner.

Application limitation
Grade K10 is intended for aluminum and nonferrous metals (group ISO N) — for turning steel or stainless steel, choose an insert from group ISO P/M. The positive, single-sided geometry provides only 2 cutting edges, and the sharp GT cutting edge is not recommended for heavily interrupted cutting.

Frequently asked questions about the CCGT 060204 insert
use, turning tool selection, and turning parameters
Two — the diamond has 2 corners with a 80° angle, and the positive geometry with a 7° clearance angle is single-sided. The insert is not flipped over because only the upper face has a chip breaker and a ground cutting edge.
Holders with a 06 diamond-shaped pocket (IC 6.35 mm): for external turning SCLCR/L and SCACR/L (entering angles of 95° and 90°) and SCMCN with cross sections of 8×8–12×12 mm; for internal turning, boring bars S0608H–S12K with the SCLCR/L or SCFCR/L designation suffix. The insert is secured with a central screw.
Mainly in the nose radius: 0.2 mm is used for finishing at low feed rates, 0.4 mm is the general-purpose version, and 0.8 mm is selected for greater depths of cut and higher feed rates. The other dimensions (IC 6.35 mm, thickness 2.38 mm) are identical, so all versions fit the same holders.
It is not designed for this — grade K10 belongs to group ISO N and is optimized for aluminum and nonferrous metals. For turning steel or stainless steel, choose an insert in a grade from group ISO P or M. K10, however, performs well in copper alloys, brass, and aluminum at speeds up to 2400 m/min.
