Parlec PC4-4405 Boring Head Twin Cutter PC4 Modular

Product Description

The PARLEC PC4-4405 is a twin-cutter boring head designed for precision diameter machining on CNC machining centers and manual boring applications. The head features an integral PC4 modular connection mount, allowing direct installation onto compatible modular tooling shanks without an adapter. With a 1.5-inch body diameter and a projection of 1.85 inches, this unit delivers rigid, compact performance in tight spindle environments. It accepts insert holders in sizes 41 and 42 and is actuated manually for fine bore diameter adjustment. Licensed machinists and tooling technicians are the primary installers and operators of this head.

The PC4-4405 is suited for use in job shops, tool rooms, and production machining environments where precise bore sizing is required. The twin-cutter design balances cutting forces and supports higher feed rates compared to single-point configurations. Minimum bore diameter is 1.58 inches (40.13 mm) and maximum bore diameter is 2.53 inches (64.26 mm), covering a practical range of finish-bore applications in steel, cast iron, and non-ferrous workpieces.

Compatibility

Designed for use with PC4 modular connection tooling systems. Compatible with insert holder sizes 41 and 42. Consult machine tool and modular tooling interface specifications to confirm spindle and shank compatibility before installation.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician familiar with modular tooling systems. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring head. Verify that all mating modular connection surfaces are clean and free of chips or burrs before assembly. Bore diameter adjustments must be made with the spindle stopped; never adjust the head while the machine is running.
