Iscar 3203344 Replaceable Tip Drill 11.5-11.9mm Sumocham

Product Description

The ISCAR 3203344 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metalworking and machining applications. It accepts a range of interchangeable drill-tip inserts, eliminating the need to replace the entire tool body when the cutting edge wears. The drill covers a diameter range of 11.5 to 11.9 mm with a maximum drill depth of 17 mm. It features a 16 mm straight-cylindrical shank and an overall length of 81.9 mm. Through-coolant capability is built in, supporting effective chip evacuation and heat control during drilling operations. This tool body is used by machinists and CNC operators working in job shops, production environments, and precision component manufacturing.

The 3203344 is suited for holemaking operations on CNC machining centers and drill presses where modular tooling systems are preferred. The DCN R toolholder style and SumoCham platform are widely used in high-volume production drilling of ferrous and non-ferrous materials. The replaceable-tip design reduces downtime between tool changes and supports consistent hole geometry across runs. Compatible insert styles include FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving the operator flexibility in selecting the appropriate tip geometry for the workpiece material.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the machine locked out before inserting or removing the drill body or tip insert. Ensure the shank seating surface and coolant port are clean and free of chips before installation. Follow the toolholder manufacturer's clamping torque procedure and verify tip seating before initiating a cutting cycle.
