Iscar 2800950 Boring Grooving Bar Holder Series Picco

Product Description

The ISCAR 2800950 is a boring and grooving bar holder designed for precision internal machining operations. It features a 0.236-inch inner diameter and a 5/8-inch outer diameter, with an overall length (OAL) of 3 inches and a head diameter of 0.71 inches. The holder is equipped with through-coolant capability, allowing coolant to be delivered directly to the cutting zone for improved chip evacuation and tool life. Belonging to the ISCAR PICCO series, this holder accepts compatible boring and grooving bars for small-bore internal turning, grooving, and profiling work on CNC lathes and turning centers. Four lock-down screws secure the bar insert firmly during operation.

This bar holder is suited for small-diameter internal machining applications on CNC lathes and turning centers. Its compact head diameter and short OAL make it appropriate for tight-bore and close-quarter grooving operations in production and job-shop environments. Through-coolant support makes it a practical choice for deeper bore applications where chip clearance and heat management are critical. Machinists and tooling technicians working with the ISCAR PICCO series will find this holder a direct-fit component for existing PICCO bar setups.

Key Features

• 0.236-inch inner diameter and 5/8-inch outer diameter for small-bore internal applications
• 3-inch overall length (OAL) with 0.71-inch head diameter for close-clearance boring and grooving
• Through-coolant design delivers coolant directly to the cutting zone
• Four lock-down screws provide secure bar clamping and repeatable positioning
• Part of the ISCAR PICCO series for compatibility with the broader PICCO tooling system

Compatibility

Designed for use within the ISCAR PICCO series boring and grooving bar system. Compatible bars and inserts must conform to the 0.236-inch bore and 5/8-inch shank specifications of this holder. Refer to ISCAR PICCO series documentation to confirm bar and insert pairing.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC lathe tooling setup. Power down and lock out the machine spindle before mounting or removing the bar holder. Ensure through-coolant lines are properly connected and free of obstruction before resuming operation. Verify torque and clamping requirements per the machine tool and ISCAR PICCO series tooling documentation before use.
