Quick Holemaking

ISCAR's innovative assembled drills with exchangeable carbide cutting heads have transformed holemaking technology, enhancing productivity and flexibility. The latest LOGIQUICK developments further push the boundaries with advanced designs for high-performance drilling solutions.

The design concept of assembled drills with exchangeable solid carbide cutting heads, adopted by ISCAR at the turn of the century, significantly altered the company's holemaking product program. In this concept, a precise carbide head is mounted in a steel holder using the "self-clamping" principle, which relies on the holder's elastic deformation, without any mechanical clamping means. 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 the assembled drills with carbide heads, the cutting head has a specially shaped rake surface to optimise chip formation, and a centring area to ensure high accuracy, with stoppers and locking sections for reliable security. The holder - the drill body - that is produced from a high-strength steel grade, features the innovative design of the head pocket, helical flutes, and internal channels for coolant supply. The advancement in technology, particularly in powder metallurgy processes and CNC machining, has made this design feasible.

The concept of assembled drills with carbide heads guarantees 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.
