Iscar 3346489 Replaceable-tip Drill 5-5.4mm Sumocham Dcn

Product Description

The ISCAR 3346489 is a SumoCham-series replaceable-tip drill body designed for precision hole-making in metalworking applications. It accepts ICP-style replaceable inserts at an Insert Seat Size 5, allowing tip changes without removing the body from the toolholder. The drill covers a diameter range of 5 to 5.4 mm (0.1969 to 0.2126 inches) with a maximum drill depth of 15 mm (0.5906 inches) at a 3xD depth-to-diameter ratio. Overall length is 61.3 mm (2.413 inches). Through-coolant capability is built in, supporting higher feed rates and longer tool life in demanding cutting conditions. This tool body is intended for use by machinists and tool-room technicians in CNC drilling operations.

The 3346489 fits into a 6 mm (0.2362 inch) straight-cylindrical shank toolholder and is suited for close-tolerance drilling in production and job-shop environments. Its right-hand cutting direction and DCN toolholder style make it compatible with standard CNC machining center setups. The replaceable-tip design reduces downtime during tip changes and is well-suited for high-volume production runs where consistent hole geometry is required across ferrous and non-ferrous materials.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Ensure the toolholder bore and shank surfaces are clean and free of debris before mounting. Through-coolant passages should be verified clear before operation. Follow the machine tool manufacturer and ISCAR tooling guidelines for clamping torque and runout verification prior to first use.
