Iscar 3201795 Indexable Insert Drill 1 in 2xd

Product Description

The ISCAR 3201795 is a 1-inch diameter indexable insert drill from the DR-TWIST series, designed for general-purpose holemaking in metal-cutting applications. It achieves a maximum drill depth of 2 inches at a 2xD depth-to-diameter ratio and accepts two SOMT 09T306 series inserts for reliable, replaceable cutting edges. The straight cylindrical shank measures 1.25 inches in diameter, making it compatible with standard milling machine and machining center toolholders. Coolant-through capability is supported via body-side and shank-end coolant ports, helping to extend insert life and improve chip evacuation during deep-hole operations.

This drill is suited for production and job-shop environments where consistent, repeatable hole quality is required in ferrous and non-ferrous materials. The DR-TWIST platform is a common choice for CNC machining centers performing high-volume holemaking. Right-hand cutting direction is standard. The 2xD configuration is well-matched to shallow-to-moderate depth bores where rigidity and chip control are priorities. Maximum achievable drill diameter reaches 1.161 inches depending on insert selection within the SOMT 09 family.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle and toolholder are fully powered down and locked out before mounting or dismounting the drill body. Verify that the toolholder bore matches the 1.25-inch shank diameter and that the tool is seated to the correct gauge length before operation. Confirm coolant supply lines and pressure settings are appropriate for through-coolant tooling before initiating a cut.
