Value Collection SC97305627 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC97305627 is a Type B rotary tool holder bushing designed for use in drill press and CNC tooling applications. It features a 1/4 inch (0.2500 inch) inside diameter and a 1-1/4 inch (1.2500 inch) outside diameter, with a length under head of 2-1/8 inches (2.1250 inches). The head thickness measures 0.265 inches. This bushing locates and guides cutting tools accurately within a drill jig or tool holder, maintaining precise alignment during drilling, reaming, or boring operations. Machinists, tool and die makers, and CNC setup technicians install this type of component during fixture assembly and production setups.

Type B tool holder bushings are used in drill jig fixtures across light manufacturing, job shops, and maintenance environments. They press or slip into a jig plate to guide twist drills, reamers, or other rotating tools on a repeatable centerline. This bushing is suited for applications requiring a 1/4 inch bore with a standard flanged head configuration that seats flush against the jig plate surface, preventing the bushing from being pushed through under axial load.

Key Features

• Type B flanged head configuration seats against the jig plate to resist axial push-through
• 1/4 inch (0.2500 inch) inside diameter for guiding quarter-inch shank tooling
• 1-1/4 inch (1.2500 inch) outside diameter for standard bushing bore fitment
• 2-1/8 inch (2.1250 inch) length under head provides adequate tool guidance depth
• 0.265 inch head thickness for positive seating against jig plate surface

Compatibility

Designed as an OEM-style replacement or direct fitment for standard Type B drill jig bushing applications requiring a 1/4 inch ID and 1-1/4 inch OD configuration.

Installation Notes

Installation is typically performed by a machinist or tool and die maker during fixture assembly or maintenance. Press-fit bushings should be installed using an arbor press to avoid damage to the bushing bore or jig plate; never drive with a hammer directly on the bushing face. Verify jig plate bore diameter and finish prior to installation to ensure proper fit class. Clean the bore and bushing exterior of chips and debris before pressing into place.
