Sandvik Coromant 6239450 Replaceable-tip Drill 22mm

Product Description

The SANDVIK COROMANT 6239450 is a replaceable-tip drill body designed for precision hole-making operations in metal cutting applications. Built on the CoroDrill 870 platform, this steel drill body accepts 870-2290-22-PM inserts in a size 22 seat, covering a drilling diameter range of 22.00 to 22.99 mm (0.8661 to 0.9051 inches). It delivers a maximum drill depth of 72.45 mm (2.8524 inches), corresponding to a 3xD depth-to-diameter ratio. The 870 LX-3 toolholder style and through-coolant capability support sustained cutting performance in demanding production environments. Overall length is 153 mm (6.0236 inches). Installation and operation are performed by machinists and CNC tooling specialists.

This drill body is suited for CNC machining centers and turning centers in both job-shop and production manufacturing settings where consistent, repeatable hole quality is required. The replaceable-tip design reduces downtime by allowing insert changes without removing the drill body from the machine, making it practical for high-volume drilling in steel and other machinable alloys. The straight cylindrical shank simplifies toolholder setup in standard ER or hydraulic chuck systems. No specific OEM machine or model compatibility is stated in the available data.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts or mounting the drill body, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Verify coolant supply connections are properly routed to support through-coolant flow before initiating a cut. Follow the toolholder manufacturer torque guidelines for clamping the shank, and confirm insert seating is correct before running at operating feed and speed.
