Iscar 2801147 Internal Grooving Toolholder Gehi Cut Grip

Product Description

The ISCAR 2801147 is a right-hand internal indexable grooving toolholder in the ISCAR Cut Grip series, designed for precision internal groove cutting on CNC lathes and turning centers. It accepts GEMI and GEPI insert families via a clamp-style insert holding method and delivers a maximum depth of cut of 0.102 inches with a groove width range of 0.075 to 0.095 inches. Overall length is 5.0 inches, shank diameter is 0.625 inches, and shank length is 4.0 inches. Through-coolant capability supports extended tool life and chip evacuation in demanding turning operations. This toolholder is installed by machinist-level CNC operators and toolroom technicians working with internal grooving and snap-ring groove applications.

The 2801147 is suited for internal grooving in both production and job-shop environments on CNC turning equipment. Its minimum bore entry requires a hole diameter of at least 0.551 inches, making it applicable for small-to-mid bore internal work. The head length is 1.0 inch with a center-to-cutting-edge dimension of 0.430 inches. The universal primary workpiece material classification covers a broad range of materials including steel, stainless, cast iron, non-ferrous, and high-temp alloys. Compatible insert size codes include GEMI, GEMI Full Radius, GEPI, GEPI Full Radius, GEPI-MT, and GEPI-WT.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CNC lathe tooling setup. Ensure the machine spindle is fully stopped and all axis motion is locked before changing or indexing inserts. Verify bore clearance meets the 0.551-inch minimum hole diameter requirement before mounting to avoid holder interference. Through-coolant connections should be confirmed leak-free before resuming cutting operations.
