Sandvik Coromant 6035701 Replaceable-tip Drill Corodrill 870

Product Description

The SANDVIK COROMANT 6035701 is a replaceable-tip drill body from the CoroDrill 870 series, designed for precision hole-making in metal cutting applications. The tool accepts 870-1690-16-PM inserts at seat size 16 and supports a drilling diameter range of 16.00 to 16.99 mm (0.6299 to 0.6689 inches). Maximum drill depth reaches 53.56 mm (2.1087 inches), corresponding to a 3xD depth-to-diameter ratio. Overall length is 122 mm (4.8032 inches). The steel body features through-coolant capability to support chip evacuation and tool life at the cutting zone. This tool is installed and changed out by machinists and CNC operators in production or job-shop environments.

The 6035701 is suited for medium-diameter drilling operations in ferrous and non-ferrous materials where indexable-tip tooling is preferred over solid-carbide drills. The straight cylindrical shank fits the 870 LX-3 toolholder style, making it compatible with standard CNC machining center spindles and tool-holding systems that accept that interface. Through-coolant delivery makes it appropriate for deeper holes where chip packing and heat buildup are concerns. The 3xD depth rating positions it for general-purpose production drilling rather than deep-hole or gundrilling work.

Key Features

• Replaceable-tip design accepts 870-1690-16-PM inserts, reducing tooling cost by replacing only the cutting tip
• Through-coolant capability for improved chip evacuation and heat management at the cutting edge
• 3xD maximum drill depth ratio (53.56 mm) suitable for general production drilling
• Straight cylindrical shank compatible with 870 LX-3 toolholder style
• Steel body construction for rigidity and vibration damping during interrupted cuts
• Flute length of 69.42 mm (2.7331 inches) provides adequate chip clearance over the full depth range

Compatibility

Compatible insert style: 870-1690-16-PM at insert seat size 16. Designed for use with the 870 LX-3 toolholder style in the CoroDrill 870 series platform.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Before changing inserts or mounting the drill body, de-energize the machine and follow lockout/tagout procedures per applicable shop safety standards. Ensure the straight cylindrical shank is fully seated and clamped to the toolholder manufacturer's specifications before operation. Confirm through-coolant passages are clear and coolant pressure is within the machine tool's rated range before initiating a drilling cycle.
