Iscar 3201336 Indexable Insert Drill 21/32 in 4xd

Product Description

The ISCAR 3201336 is a straight-shank indexable insert drill from the DR-TWIST series, designed for holemaking in metal fabrication and machining operations. It accepts two indexable inserts and produces a nominal hole diameter of 21/32 inches (0.6560 inches decimal) with a maximum drill diameter of 0.7130 inches. Maximum drill depth reaches 2.63 inches at a 4xD depth-to-diameter ratio. The 3/4-inch straight cylindrical shank seats securely in standard drill chucks or tool holders. Coolant-through capability is built in, supporting both body-side and shank-end coolant delivery for heat management and chip evacuation during general-purpose drilling.

This drill body is suited for general-purpose holemaking in production machining environments, including CNC machining centers and drill presses equipped for indexable tooling. The 4xD depth ratio makes it appropriate for moderate-depth holes in ferrous and non-ferrous materials. It is installed and serviced by machinists and tool-crib technicians working with standard indexable insert tooling systems. Compatible insert grades and geometries allow the same body to be configured for a range of workpiece materials without changing the drill body itself.

Key Features

• 21/32 inches (0.6560 inches) nominal drill diameter with 0.7130 inches maximum drill diameter
• 4xD depth ratio with 2.63 inches maximum drill depth
• Accepts 2 indexable inserts — compatible with SOGX-AL, SOMX-DT, and SOMX-GF insert styles
• Coolant-through design with body-side 1/16-27 thread and shank-end 1/4-18 thread coolant ports

Compatibility

Compatible insert styles include SOGX-AL, SOMX-DT, and SOMX-GF. This drill body is part of the ISCAR DR-TWIST series and uses a 3/4 inches modular connection size. Verify insert compatibility against the specific insert grade and geometry required for the workpiece material before ordering inserts separately.

Installation Notes

Installation and insert indexing should be performed by a qualified machinist with the machine powered down and locked out per applicable safety procedures. Ensure the shank is fully seated and clamped to the specified tool-holder torque per the machine manufacturer guidelines before operation. Coolant line connections at both the body-side and shank-end ports should be inspected for proper seating to maintain through-coolant flow. Handle indexable inserts with care during changeover to avoid edge chipping.
