Value Collection SC84949841 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949841 is a Type B rotary tool holder bushing designed for use in drill jigs, fixtures, and machine tooling setups. It features an inside diameter of 0.625 inches and an outside diameter of 1.75 inches, with a 3-inch length under the head and a head thickness of 0.295 inches. This bushing guides cutting tools such as drills, reamers, and boring bars during precision machining operations. Machinists, tool and die makers, and CNC setup technicians install these bushings in production and maintenance environments to maintain positional accuracy and reduce tool wander during drilling or boring cycles.

The SC84949841 is suited for use in drill jig assemblies in both production machine shops and maintenance repair operations. Its Type B designation identifies the head style, which is appropriate for applications where the bushing must be retained in the jig plate while allowing tool entry from the top. This bushing fits standard jig plate bores sized for 1.75-inch OD bushings and accepts tooling with a 0.625-inch shank or guide diameter.

Key Features

• Type B head style for retained-bushing jig plate installations
• Inside diameter of 0.625 inches for guiding compatible cutting tool shanks
• Outside diameter of 1.75 inches for standard jig plate bore fitment
• 3-inch length under head provides extended tool guidance depth
• Head thickness of 0.295 inches for positive seating against the jig plate surface

Compatibility

Designed as a standard Type B tool holder bushing for use in drill jigs and fixture plates bored to accept a 1.75-inch OD bushing with a 0.625-inch inside diameter guide bore.

Installation Notes

Installation is typically performed by machinists or toolmakers. The bushing is pressed or slip-fit into a prepared jig plate bore machined to the appropriate tolerance for the selected fit class. Ensure the jig plate bore is clean and free of burrs before installation. Do not force the bushing with a hammer strike to the head; use an appropriate press or driver to avoid damage to the head face or bore surface.
