In the field of precision turning, balancing efficiency and accuracy has always been the core goal for manufacturers. As a high-performance 55° diamond-shaped CNC insert, DNMG150608-SF 1105 provides a perfect solution for precision cutting of steel, stainless steel and cast iron with its excellent material formula and optimized chip breaker design. Whether for mass production of auto parts or high-precision requirements of mold accessories, this insert can achieve higher processing quality at lower unit cost.

• Carbon Steel (P Class): Cutting speed 170-500 m/min, Feed rate 0.1-0.4 mm/rev, Depth of cut 0.3-2 mm
• Stainless Steel (M Class): Cutting speed 120-300 m/min, Feed rate 0.1-0.3 mm/rev, Depth of cut 0.3-1.5 mm
• Cast Iron (K Class): Cutting speed 150-400 m/min, Feed rate 0.15-0.4 mm/rev, Depth of cut 0.3-2 mm

1. Super Long Durability: 1105 grade adopts ultra-fine grain carbide substrate combined with TiAlN coating to form double protection, which increases the service life by more than 30% compared with ordinary coated inserts, especially suitable for continuous cutting conditions.
2. Excellent Chip Control: SF chip breaker is optimized by fluid mechanics, which can stably control chip curling and breaking in the range of light to medium cutting, effectively avoiding chip wrapping around workpieces or tools and reducing downtime for cleaning.
3. High Precision Surface Quality: 0.8mm corner radius and precision grinding process ensure the machined surface roughness Ra ≤ 1.6μm, meeting the surface requirements of precision parts such as automobile engine blocks and hydraulic valve blocks.

Precision turning of crankshafts and camshafts, achieving stable dimensional accuracy in mass production

Semi-finishing to finishing of mold steel, ensuring the processing quality of complex surfaces

Precision turning of valve cores and oil cylinders, meeting strict tolerance and surface finish requirements

This insert is suitable for ISO standard negative rake angle tool holders such as DCLNR and DCMTN series. It realizes quick change through center hole positioning, with repeat positioning accuracy up to ±0.005mm. It is recommended to use with cooling fluid to obtain the best processing effect and insert life.
