Iscar 3202790 Replaceable-tip Drill 12-12.4mm 16mm Shank

Product Description

The ISCAR 3202790 is a replaceable-tip drill from the SumoCham series, designed for precision holemaking in metalworking and machining operations. It accepts a range of interchangeable insert tips to allow diameter adjustment from 12 to 12.4 mm without replacing the full drill body. The DCN-style toolholder body measures 101 mm in overall length with a 16 mm straight-cylindrical shank. Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting longer tool life and improved chip evacuation in deep-hole applications. Seat size 12 inserts are compatible with this body. This tool is typically installed and operated by machinists and CNC tooling specialists in production shop environments.

The 3202790 is suited for holemaking operations requiring a maximum drill depth of 36 mm, with a 3xD depth-to-diameter ratio. The through-coolant design makes it well-suited for ferrous and non-ferrous materials where heat and chip buildup are concerns. Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M, giving the operator flexibility in cutting geometry selection based on workpiece material and application requirements. This drill body is appropriate for use in CNC machining centers and other machine tools with coolant-through spindle capability.

Key Features

• Replaceable-tip design with seat size 12 accepts FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M insert styles
• Through-coolant construction directs fluid to the cutting edge for improved chip evacuation and thermal control
• Drill diameter range of 12 to 12.4 mm accommodates slight diameter variation without changing the body
• 3xD depth-to-diameter ratio supports a maximum drilling depth of 36 mm
• 16 mm straight-cylindrical shank for secure, repeatable tool holding in standard chuck or collet systems
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Compatible insert styles for this drill body are FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M at seat size 12. Designed as an OEM-style replacement or primary tooling selection for CNC holemaking setups using SumoCham series DCN-style drill bodies.

Installation Notes

Installation and insert changes should be performed by qualified machinists following the machine tool manufacturer lockout and energy-isolation procedures before any tooling work. Ensure the straight-cylindrical shank is fully seated and clamped to the torque specification defined by the toolholder manufacturer. Through-coolant systems should be verified for proper pressure and flow before initiating a drilling cycle. Consult the insert manufacturer documentation for recommended cutting parameters, as this drill body is a holder only and performance depends on the selected insert geometry.
