Sandvik Coromant 6035714 Replaceable-tip Drill Corodrill 870

Product Description

The SANDVIK COROMANT 6035714 is a replaceable-tip drill body from the CoroDrill 870 series, designed for precision hole-making in metal cutting applications. It accepts 870-1790-17-PM inserts at insert seat size 17, covering a drill diameter range of 17 to 17.99 mm (0.6693 to 0.7083 inches). The tool body is constructed from steel, features a 20 mm straight-cylindrical shank, and delivers a maximum drill depth of 56.71 mm (2.2327 inches) at a 3xD depth-to-diameter ratio. Through-coolant capability supports chip evacuation and tool life in demanding materials. Overall length is 126 mm (4.9606 inches). This tool is intended for installation by machinists and CNC tooling technicians in production and job-shop environments.

The 6035714 drill body is suited for use in CNC machining centers and turning centers where repeatable, close-tolerance drilling is required. The replaceable-tip design allows the cutting insert to be swapped without removing the body from the spindle, reducing downtime during production runs. The straight-cylindrical shank interfaces directly with standard ER or hydraulic chucks and toolholders dimensioned for a 20 mm shank. Typical applications include drilling in steel, stainless steel, and cast iron in both low-volume and high-volume production settings.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC tooling technician with the machine spindle fully stopped and the machine in a locked-out state per applicable safety procedures. Ensure the shank seating surface and toolholder bore are clean and free of chips before mounting. Replaceable tips must be seated fully and secured according to the insert manufacturer torque specifications provided in the tooling documentation supplied with the insert. Do not exceed the maximum drill depth of 56.71 mm in a single pass without confirming programmed depth limits in the machine controller.
