Sandvik Coromant 6239456 Replaceable-tip Drill 23mm

Product Description

The SANDVIK COROMANT 6239456 is a replaceable-tip drill body from the CoroDrill 870 series, designed for precision hole-making in metal cutting applications. The body accepts 870-2390-23-PM inserts at insert seat size 23, covering a drill diameter range of 23.00 to 23.99 mm (0.9055 to 0.9445 inches). Maximum drill depth reaches 75.59 mm (2.976 inches), reflecting a 3xD depth-to-diameter ratio. Overall length is 157 mm (6.181 inches). The steel body features integrated through-coolant delivery, supporting high-feed drilling operations where heat management and chip evacuation are critical. This tool body is installed by machinists and CNC operators in production and job-shop environments.

The 6239456 drill body is suited for CNC machining centers and turning centers running ferrous and non-ferrous materials where consistent hole quality in the 23 mm diameter range is required. The straight cylindrical shank fits standard toolholders compatible with the 870 LX-3 toolholder style. The replaceable-tip system allows worn inserts to be swapped at the machine without disturbing the body setup, reducing downtime in high-volume production runs. Through-coolant capability makes it practical for deep-hole applications approaching the 75.59 mm depth limit.

Installation Notes

This drill body is serviced by machinists and CNC tooling technicians. Ensure the machine spindle and coolant supply are fully shut down before changing inserts or mounting the body. Verify insert seat cleanliness and proper insert seating torque per the tool manufacturer documentation before initiating a cut. Confirm through-coolant passages are clear and coolant pressure is within the machine specification before deep-hole operations.
