    When it comes to extending service life, this company knows the drill!

    SANDVIK COROMANT, the world market leader for tools and machining solutions, is attending EMO Hannover 2019 to debut the very first indexable insert drill for drilling depths of 7×D - the CoroDrill DS20. This brand-new solution promises to ensure longer tool life for 4-7×D applications in particular.

    As an indexable insert drill for drilling depths of 7×D, the CoroDrill DS20 without a centering tip is the first of its kind capable of achieving such depths. The drill, which includes completely new designs both for its base body and indexable inserts, reportedly provides reliable, predictable chip control and outstanding penetration rates in all 4-7×D applications.

    As the worthy successor to the existing CoroDrill 880 and 881, the indexable 4-5×D CoroDrill DS20 can – according to SANDVIK COROMANT - offer up to 25 percent better tool life and boost productivity by up to 10 percent, depending on the workpiece material. The 6-7×D variants are set to open up a whole new level of performance in the indexable insert drill segment. Alongside these new arrivals on show at EMO Hannover 2019, the company is also exhibiting its new modular drilling interface (MDI) that serves as a coupling between drill and adapter. The MDI adapter is available with the spindle-side Coromant Capto and HSK shank types and is designed to provide high precision and outstanding centering capabilities, thus reducing the number of tools required.

    "Controlled cutting forces, reliable chip removal and excellent centering capabilities are some of the most important factors when drilling holes deeper than 5×D," explains Håkan Carlberg, senior R&D engineer for indexable drilling at SANDVIK COROMANT. "Switching from a 5×D to a 7×D drill triples the theoretical complexity due to increased bending tendencies. When designing a 7×D CoroDrill DS20, there are around 50 parameters that require very close attention - all of which are interlinked. This improves process reliability by reducing forces and facilitating cutting, particularly upon entry. As a result, users benefit from lower costs per drill hole, the option to drill deeper and reduced noise levels."

    The CoroDrill DS20 indexable insert drills are available with a diameter of 15 to 65 millimeters and a selection of shank types, indexable insert sizes, types and geometries for all material types and applications - even those found in the general mechanical engineering, automotive, oil and gas, pump and valve, and aerospace industries.
