Sandvik Coromant 6035732 Replaceable-tip Drill 18-18.99mm

Product Description

The SANDVIK COROMANT 6035732 is a replaceable-tip drill body in the CoroDrill 870 series, engineered for precision hole-making in metal cutting applications. The body accepts 870-1890-18-PM inserts at insert seat size 18, covering a drill diameter range of 18.00 to 18.99 mm (0.7087 to 0.7476 inches). Maximum drill depth reaches 97.84 mm (3.852 inches), yielding a 5xD depth-to-diameter ratio. The steel body features a straight-cylindrical shank and through-coolant capability, supporting high-speed drilling operations where heat and chip evacuation are critical. Machinists and CNC operators in production and job-shop environments are the primary installers.

This drill body is suited for use on CNC machining centers and turning centers where consistent, repeatable hole quality is required. The toolholder style is 870 LX-5, and the replaceable-tip design allows quick insert changes at the machine without removing the body from the spindle, reducing downtime in production settings. Through-coolant delivery directs fluid directly to the cutting edge, making this body well-suited for interrupted cuts, deep holes, and difficult-to-machine materials common in aerospace, automotive, and general metalworking operations.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is locked out before changing inserts or mounting the drill body. Verify that the insert seat is clean and free of chips before seating a new tip, as contamination can affect runout and hole quality. Confirm through-coolant passages are clear and that machine coolant pressure is appropriate for the application before beginning a drilling cycle.
