The CoroDrill® DS20 from cutting tool and tooling system specialist Sandvik Coromant is the first indexable drill concept capable of producing hole depths up to 7xD. The drill, which includes completely new designs for both the body and inserts, provides users with reliable, predicatable chip control and outstanding penetration rates in all 4-7xD applications.
Replacing the existing CoroDrill 880 and CoroDrill 881 tools, 4-5xD CoroDrill DS20 indexable drills provide tool life improvements of up to 25% and productivity gains up to 10%, depending on workpiece material. The 6-7xD variants represent an entirely new capability range of indexable drills from Sandvik Coromant. To complement the introduction, the company is releasing a new Modular Drilling Interface (MDI) that acts as a coupling between the drill and the back-end. Available in Coromant Capto® and HSK shank types, the MDI-adapter provides high precision, excellent centering capabilities and reduced tool inventory.
In addition, next-generation ‘double-step’ technology reduces entry cutting forces by up to 75% compared with CoroDrill 880 tools to improve centring capabilities. Strong insert design and bulk strength provide extra toughness, with four true cutting edges provided on both centre and peripheral inserts.
CoroDrill DS20 indexable drills are available from 15 to 65 mm in diameter with a selection of shank types, insert sizes, grades and geometries to suit all material types and applications, including those found across the general engineering, automotive, oil and gas, pump and valve, and aerospace sectors.
