Sandvik Coromant 6035616 Replaceable-tip Drill 11-11.49mm

Product Description

The SANDVIK COROMANT 6035616 is a replaceable-tip drill body from the CoroDrill 870 series, designed for precision hole-making in metal-cutting applications. The tool accepts 870-1140-8-PM inserts at insert seat size 8, enabling quick tip changes without removing the body from the machine. It covers a drill diameter range of 11 to 11.49 mm (0.4331 to 0.4524 inches) and reaches a maximum drill depth of 36.23 mm (1.4264 inches), corresponding to a 3xD depth-to-diameter ratio. Through-coolant capability is built in, directing cutting fluid directly to the cutting zone to extend insert life and aid chip evacuation. The steel body measures 99 mm (3.8976 inches) overall length with a straight-cylindrical shank. This tool is installed and operated by CNC machinists and tooling specialists in production or job-shop environments.

The 6035616 is suited for drilling operations on machining centers and CNC lathes where repeatable hole quality and fast insert indexing are priorities. The CoroDrill 870 platform is a modular system, and this body is configured in the 870 LX-3 toolholder style. Typical applications include hole-making in steel, cast iron, and similar workpiece materials in both batch and high-volume production settings. The through-coolant feature makes it especially practical for deeper holes where chip packing and heat buildup are concerns.

Installation Notes

Installation and tool changes should be performed by qualified machinists following the machine tool manufacturer spindle lockout and energy isolation procedures before any insert seating or body mounting work. Ensure the coolant-through channels in the holder and spindle are clear and properly aligned before clamping. Use the correct torque wrench and insert-tip screw driver specified by SANDVIK COROMANT for the 870 series to seat the replaceable tip securely. Do not exceed the maximum drill depth or recommended feed and speed parameters for the insert grade in use.
