ISCAR'S INNOVATIVE DRILLING SOLUTIONS

ISCAR revolutionised holemaking by introducing assembled drills with exchangeable solid carbide cutting heads, enhancing machining performance and tool design. Their latest innovation, LOGIQ3CHAM, features a three-flute design that increases productivity by up to 50 per cent compared to traditional two-flute drills.

At the turn of the century, ISCAR introduced a groundbreaking design concept: assembled drills with exchangeable solid carbide cutting heads. This innovation significantly transformed the company's holemaking product programme. The concept involves mounting a precise carbide head into a steel holder using a "self-clamping" principle, which relies on the holder's elastic deformation, eliminating the need for mechanical clamping mechanisms. This approach is characteristic of various successful ISCAR products, such as the SELF-GRIP and MULTI-MASTER tool lines, which have not only substantially improved machining performance but also revolutionised traditional perspectives on cutting tool design.

In these assembled drills, the cutting head features a specially shaped rake surface to optimise chip formation, a centering area to ensure high accuracy, and stoppers and locking sections for reliable security. The holder—the drill body—is produced from high-strength steel and boasts an innovative design, including the head pocket, helical flutes, and internal channels for coolant supply. Advancements in technology, particularly in powder metallurgy processes and CNC machining, have made this design feasible.

The concept of assembled drills with carbide heads offers several key advantages:

1. Due to its rigid structure, reliable clamping principle, unique cutting geometry, and advanced carbide grade of the heads, the drills guarantee productive results. This significantly reduces cycle times and enables high-quality holes. These drills can be used for machining a wide range of materials including steel, stainless steel, cast iron, titanium, and high temperature alloys.
