Iscar 3201801 Indexable Insert Drill 1-1/4 in 2xd

Product Description

The ISCAR 3201801 is an indexable insert drill from the DR-TWIST series, designed for holemaking operations in machining environments. It accepts two SOMT-style inserts and produces holes up to 1.25 inches in diameter at depths up to 2.5 inches, delivering a 2xD depth-to-diameter ratio. The straight cylindrical shank measures 1.25 inches in diameter and 3.0 inches in length, allowing secure clamping in standard tool holders. Coolant-through capability is supported at both the shank end and body side, improving chip evacuation and extending insert life during general-purpose drilling applications. This tool is installed and operated by machinists and CNC operators in production and job-shop environments.

The 3201801 is suited for general-purpose holemaking in CNC machining centers and manual machines where a 1.25-inch diameter straight-shank drill body is required. The 2xD ratio makes it appropriate for through-holes and shallow blind holes in a range of workpiece materials depending on insert grade selection. The drill body measures 6.80 inches overall length with a 3.80-inch body length, and accommodates SOMT insert styles including SOMT-DT, SOMT-GF, and SOMT-HD in size code 09.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the tool holder de-energized before mounting or insert indexing. Confirm shank clamping torque and runout per the machine tool builder specifications before cutting. Coolant-through connections at both ends should be verified for proper seating and thread engagement before operation.
