The Arno AKB drill offers optimised swarf chambers which extend right up to the collar. In addition, AKB drills are coated and polished, which improves swarf evacuation, while an internal coolant channel allows direct cooling of the flute. With Torx-Plus screws, the inserts can be changed quickly. Four geometries for steel and non-ferrous metals ensure a range of applications can be covered.

Another upgrade is Shark-Drill, an indexable-insert drill for diameters of 9.5 to 114 mm. The nickel-plated carrier tool with integrated coolant supply is available with a straight or spiral flute for Weldon or Morse tapered holders. For example, Shark-Drill can be used as a rotating tool (spiral flute) while the workpiece is stationary, or as a stationary tool (straight flute) while the workpiece is rotating.

The Shark-Drill series includes 12 variants for drilling depths up to 32xD, or from 290 to 939 mm. Three geometries for cutting inserts – universal, AS with good centring properties and flat-bottom drilling inserts – cover a range of machining applications. With HSS indexable inserts, Shark-Drill is said to be a universal and cost-effective problem-solver.

With Shark-Drill2, Arno has developed a drilling system that combines the advantages of a solid-carbide twist drill with interchangeable cutting inserts. Equipped with a carbide insert which can be replaced while the tool remains in the machine, this tool can operate at very high feed rates. Drilling depths of 2xD, 3xD, 5xD and 8xD are possible with diameters from 14 to 32 mm.

For those who want to combine drilling and milling, Shark-Cut is a multifunction tool that can do both. Mini, Standard and Rebore are three variants that make drilling possible for diameters of 4, 8 and 12 mm respectively. Likewise, internal and external diameters can be machined and flat surfaces created. This combination tool thus reduces the number of tool changes required and accelerates the respective processes.
