Value Collection SC05879549 Type C Rotary Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879549 is a Type C rotary tool holder bushing used in CNC machining and precision tooling applications. It provides a fixed, press-fit or slip-fit interface between a rotating tool and the tool holder or jig plate, keeping the tool accurately located during operation. The bushing features a 0.75-inch inside diameter, a 1.75-inch outside diameter, and a head thickness of 0.295 inches. With a length under head of 3.5 inches and a slot length of 3.125 inches, this bushing is sized for deeper tooling setups that require extended reach below the mounting surface. Machinists and tool and die technicians install this type of component during machine setup or fixture assembly.

This Type C bushing is suited for use in drill jigs, boring fixtures, and similar precision machining setups found in job shops, production machine shops, and maintenance environments. Its extended slot length makes it appropriate for applications where chip clearance or tool engagement depth is a design requirement. Installation is performed during fixture build or machine teardown and rebuild, typically on manual or CNC vertical machining centers and drill presses.

Key Features

• Type C bushing design with flanged head for positive axial location
• 0.75-inch inside diameter with 0.7500-inch decimal precision for close-tolerance tool fit
• 1.75-inch outside diameter provides a stable press or slip fit in the jig plate bore
• 3.5-inch length under head accommodates deep fixture or plate installations
• 3.125-inch slot length supports chip clearance and extended tool engagement
• Head thickness of 0.295 inches (approximately 3/16 inch) for a low-profile mounting face

Compatibility

Designed as an OEM-style replacement or direct fitment bushing for drill jig fixtures and tool holder assemblies requiring a Type C configuration with 0.75-inch ID and 1.75-inch OD.

Installation Notes

Tool holder bushings of this type are installed by machinists or toolmakers during fixture assembly or maintenance. Before installation, ensure the receiving bore in the jig plate is clean, free of burrs, and dimensionally verified to the required tolerance for the bushing type. Use appropriate press or arbor tooling when pressing the bushing into the plate to avoid cocking or surface damage. Follow shop-standard fixture assembly procedures and verify concentricity after installation before placing the fixture into service.
