Sandvik Coromant 5723779 Indexable Insert Drill 1.062in 4xd

Product Description

The SANDVIK COROMANT 5723779 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. Built on the CoroDrill 880 platform, this drill body accepts two indexable inserts in the A880..LXxx-04 drill style and delivers a maximum drill depth of 4.375 inches at a 4xD depth-to-diameter ratio. The drill diameter is 1.062 inches, with a 1.25-inch straight cylindrical shank for rigid machine spindle engagement. Coolant-through capability supports chip evacuation and tool life in demanding cut conditions. The tool body is constructed from steel and is intended for use by machinists and CNC operators in job shop and production environments.

This indexable insert drill is suited for through-hole and blind-hole drilling operations on machining centers and CNC lathes where a straight-shank interface is required. The 4xD depth ratio makes it appropriate for moderate-depth bores in ferrous and non-ferrous workpiece materials. Typical applications include drilling operations in automotive, aerospace, and general manufacturing production runs where insert replaceability reduces downtime compared to brazed or solid carbide tooling. The CoroDrill 880 series is a recognized platform for high feed-rate drilling with two-insert geometry that balances center and periphery cutting loads.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in an E-stop or locked-out state before mounting or removing the drill body. Verify shank seating depth and runout with a dial indicator before production use, and confirm coolant-through passages are clear and properly pressurized per machine specifications. Do not exceed the maximum drill depth or recommended feed rates for the insert grade in use.
