Value Collection SC05879135 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879135 is a Type J rotary tool holder bushing used to locate and support cutting tools in drill jigs and tooling fixtures. With a 1.25-inch inside diameter, a 1.5-inch outside diameter, and a 2.5-inch length under the head, this bushing guides twist drills, reamers, and boring bars with consistent positional accuracy. The head thickness measures 0.265 inches, providing a stable shoulder that seats flush against the jig plate. This component is installed by machinists, tool and die makers, and production tooling technicians as part of fixed or renewable bushing assemblies.

Type J bushings are used in drill jig applications across metalworking, manufacturing, and general machining environments. This bushing fits into standard jig plate bores where a headed, press-fit or slip-fit design is required to maintain tool alignment during drilling and reaming operations. The 1.125-inch distance between hole centers spec supports accurate multi-hole jig layouts. Suitable for both prototype and production tooling setups in machine shops and fabrication facilities.

Key Features

• Type J bushing geometry with a 0.265-inch head thickness for positive shoulder seating
• 1.25-inch inside diameter accommodates standard tool shanks and drill bodies
• 1.5-inch outside diameter for press or slip fit into standard jig plate bores
• 2.5-inch length under head provides extended tool guidance for deeper workpieces
• 1.125-inch distance between hole centers supports multi-hole jig layouts

Compatibility

Designed as a standard Type J tool holder bushing for use in drill jigs and machining fixtures requiring a 1.25-inch ID and 1.5-inch OD headed bushing configuration.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Press-fit bushings should be installed using an arbor press to avoid damage to the bore or bushing head. Verify jig plate bore diameter and finish before installation. Do not hammer bushings directly without a proper installation driver, as this can distort the OD and affect tool guidance accuracy.
