Seco 00056767 Boring Head Shank Extension Graflex 6

Product Description

The SECO 00056767 is a boring head shank extension designed for precision metal-cutting operations on machining centers and boring mills. It features a Graflex 6 inside modular connection and a Graflex 6 outside modular connection, making it a same-size pass-through extension within Graflex 6 tooling assemblies. The 4.724-inch projection adds reach between the spindle and the boring head, allowing access to deeper bores or recessed features without changing the core tooling setup. The nose diameter measures 2.48 inches. This component is handled and installed by machinists or tooling technicians working with modular boring systems.

This shank extension is suited for horizontal and vertical boring operations in manufacturing environments where extended reach is required. It fits into modular tooling chains that use Graflex 6 interfaces on both the machine side and the tool side. Typical applications include deep-bore finishing, large-diameter rough boring, and tooling assemblies on CNC machining centers or dedicated boring mills where standard-length holders fall short of the workpiece feature depth.

Key Features

• Graflex 6 inside modular connection for direct spindle or adapter interface
• Graflex 6 outside modular connection for compatible boring head attachment
• 4.724-inch projection provides extended reach for deep-bore applications
• 2.48-inch nose diameter supports large-diameter boring head configurations
• Modular design integrates into existing Graflex 6 tooling chains without additional adapters

Compatibility

Designed for use in modular boring tooling assemblies that utilize Graflex 6 inside and outside modular connections on both the machine and tool interfaces.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before assembling or disassembling modular tooling components. Clean all mating surfaces and connection interfaces before assembly to ensure proper seating and runout accuracy. Follow the machine tool manufacturer's torque and clamping specifications for the Graflex modular connection system.
