Iscar 3260104 Replaceable-tip Drill Sumocham Series

Product Description

The ISCAR 3260104 is a replaceable-tip drill body from the SumoCham series, designed for holemaking operations in metal cutting applications. The drill body accepts ICK, ICM, and ICP style inserts at insert seat size 26, allowing the cutting tip to be swapped without removing the holder from the machine. It covers a drilling diameter range of 1.024 to 1.059 inches with a maximum drill depth of 3.07 inches, representing a 3xD depth-to-diameter ratio. The DCN-style toolholder body measures 4.7 inches in body length and 7.06 inches overall, with through-coolant capability to flush chips and manage heat at the cutting zone. Shank diameter is 1.25 inches with a Weldon flat configuration. Package weight is 0.25 pounds.

This drill body is suited for production machining environments where consistent hole quality and fast tip changeovers are required. The replaceable-tip design reduces downtime by eliminating the need to regrind or replace the entire drill assembly. Through-coolant delivery makes it well-suited for deep-hole work in ferrous and non-ferrous materials where chip evacuation is critical. The Weldon flat shank seats securely in standard driven toolholders and machining center spindles. Machinists and CNC operators performing holemaking on production lines, job shops, or maintenance machining will find this body a direct fit for high-volume drilling cycles.

Key Features

• Replaceable-tip design accepts ICK, ICM, and ICP insert styles at seat size 26 for fast tip changes
• Through-coolant construction channels fluid directly to the cutting zone for chip evacuation and heat control
• 3xD depth-to-diameter ratio supports drilling up to 3.07 inches deep in a single pass
• Weldon flat shank at 1.25 inches diameter provides positive drive and slip resistance in standard holders
• SumoCham DCN series body conforms to ISO 13399 tooling data standards
• Compact 0.25-pound body weight reduces spindle load during extended drilling cycles

Compatibility

Compatible with ICK, ICM, and ICP style replaceable drill tips at insert seat size 26. Designed for use with standard Weldon flat-driven toolholders accepting a 1.25-inch shank diameter. Drilling diameter range of 1.024 to 1.059 inches is determined by the insert tip selected.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or CNC tooling technician with the machine spindle fully stopped and locked out. Ensure the Weldon flat shank is fully seated and the drive screw is properly tightened against the flat before operation. Verify coolant passages are clear and through-coolant pressure is set per the machining center specifications before drilling. Follow the toolholder manufacturer torque guidance for the drive screw and inspect the insert seat for debris or wear at each tip change.
