The GC1030 and GC4240 inserts allow for high efficiency in steel milling. GC1030 uses a PVD coating to improve wear resistance. This makes it extremely versatile and reliable, according to the company. GC4240 contains a new substrate and CVD coating for security. It excels in shoulder milling or other demanding steel milling operations requiring high metal removal rates, developers say. GC1030 is also said to perform well in titanium and high temperature alloys.

The GC4225 is a turning grade that optimizes roughing and finishing operations in steel turning by using a combination of features to enhance reliability and productivity. This is done through better surface finishes, higher feed rates and cutting speeds and improved plastic deformation and crater wear resistance.

The company’s CoroMill 365 represents a new concept in cast iron milling by using a strong, stable cutting body and precision ground inserts to achieve high metal removal and feed rates. The extra close pitch cutters use a wedge clamp design to enhance production economy, the company says. Inserts in this grade feature as many as eight cutting edges.

In the area of toolholding, the company’s Coromant Capto damped milling adaptor is designed to virtually eliminate vibration during end milling or profile milling with overhangs as many as seven times the tool diameter.

The CoroDrill 805 enables drilling of holes with a depth as many as 15 times the hole diameter, without moving the workpiece to a dedicated machine or requiring extra coolant pump capacity. Additions to the CoroDrill 880 line use “step technology” for a 100-percent increase in feed rates, according to the company.
