Value Collection SC84949718 Rotary Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949718 is a Type B rotary tool holder bushing designed for use in drill jigs, fixtures, and precision machining setups. It provides a hardened, accurately sized bore to guide cutting tools and maintain positional accuracy during repeated drilling operations. With a 0.375-inch inside diameter, a 1.25-inch outside diameter, and a 2.125-inch length under the head, this bushing fits standard press-fit or liner-bushing installations common in production and toolroom environments. The 0.265-inch head thickness seats flush against the jig plate to prevent axial movement during operation. Machinists, toolmakers, and CNC setup technicians are the primary installers.

This Type B bushing is suited for fixed renewable and press-fit jig bushing applications in both production machining and one-off fixture work. It is commonly installed in drill jig plates where repeatable hole location is required across multiple workpieces. The head style prevents the bushing from being pushed through the jig plate under downward tool pressure. Applications include drilling, reaming, and light boring operations on metalworking fixtures in job shop and manufacturing environments.

Key Features

• Type B head style seats against jig plate surface to resist axial push-through
• 0.375-inch inside diameter for standard drill and reamer guidance
• 1.25-inch outside diameter for common liner bushing and press-fit bore sizing
• 2.125-inch length under head accommodates jig plates of varying thickness
• 0.265-inch head thickness provides a low-profile, stable seating surface
• Sold individually, no minimum pack quantity required

Compatibility

Designed as a standard Type B rotary tool holder bushing for use in drill jig fixtures requiring a 0.375-inch bore and 1.25-inch outside diameter press or liner fit.

Installation Notes

Installation is typically performed by toolmakers or machinist personnel using an arbor press to seat the bushing into a precision-bored jig plate hole. Ensure the receiving bore is clean, properly sized, and free of burrs before pressing the bushing into position. Do not hammer the bushing directly without a suitable driver to avoid damaging the head or distorting the bore. Verify inside diameter clearance with the intended drill or reamer before final assembly.
