Value Collection SC84949908 Rotary Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949908 is a Type B rotary tool holder bushing designed for use in drill jigs and precision machining setups. The bushing features a 0.5-inch inside diameter, a 2-inch outside diameter, and a 3.5-inch length under the head, with a head thickness of 0.295 inches. This style of press-fit or slip-renewable bushing guides cutting tools such as drills, reamers, and counterbores with consistent positional accuracy. Machinists, tool and die makers, and CNC setup technicians install this type of component when a jig fixture requires a replaceable wear element to maintain hole-location tolerances over repeated production cycles.

Type B rotary tool holder bushings are suited for applications where the bushing must rotate with the tool rather than remaining stationary in the jig plate. This makes them appropriate for moderate-speed drilling and reaming operations in both production and job-shop environments. The 2-inch OD and 3.5-inch length under head accommodate deeper workpiece sections or thicker jig plates that require extended tool guidance. This part is sold individually and is a standard catalog item for toolroom and fixturing applications.

Key Features

• Type B configuration allows bushing rotation with the cutting tool for reduced friction during operation
• 0.5-inch inside diameter guides standard drill and reamer shanks with close tolerances
• 2-inch outside diameter seats securely in compatible jig plate bores
• 3.5-inch length under head provides extended tool guidance for thicker workpieces or jig plates
• 0.295-inch head thickness retains the bushing axially against the jig plate surface
• Weighs 2.09 pounds, indicating a solid, full-section construction appropriate for repeated production use

Compatibility

Designed as a standard Type B rotary tool holder bushing for use in drill jig fixtures requiring a rotating-style liner bushing with a 0.5-inch bore and 2-inch OD seating diameter.

Installation Notes

Installation is typically performed by a machinist or toolroom technician during jig assembly or bushing replacement. Ensure the mating jig plate bore is clean and dimensionally correct before seating the bushing. Do not force the bushing with impact tools if resistance is encountered, as this may damage the bore or distort the bushing head. Always verify that the jig plate and fixture are secured before resuming cutting operations.
