Value Collection SC84949809 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949809 is a Type B rotary tool holder bushing used in machine tool setups to locate and support cutting tools within a drill jig or fixture. It features a 0.875-inch inside diameter, a 1.5-inch outside diameter, and a 2.5-inch length under the head. The head thickness measures 0.265 inches. This bushing is installed by machinists and toolroom technicians working with drill presses, CNC machining centers, and manual milling or boring equipment where precise tool alignment is required. The hardened construction typical of this bushing type provides wear resistance during repeated drilling or reaming cycles.

Type B tool holder bushings are used in jig and fixture applications across general machining, production manufacturing, and toolroom environments. They are seated into a mating liner bushing or directly into a jig plate to guide drill bits, reamers, or other rotary cutting tools on-center. This bushing is suited to setups requiring a renewable, slip-fit or press-fit component that can be replaced without reworking the fixture. It is applicable in both light-duty prototype work and higher-volume production drilling operations.

Key Features

• Type B bushing configuration with a flanged head for positive axial location
• Inside diameter of 0.875 inches for standard tooling compatibility
• Outside diameter of 1.5 inches for seating in matching liner bushings or jig plates
• Length under head of 2.5 inches provides extended tool guidance depth
• Head thickness of 0.265 inches for secure flange seating against the fixture surface
• Weighs 1.804 pounds — solid construction suitable for repeated use in production fixtures

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig and fixture assemblies requiring a Type B rotary tool holder bushing with a 0.875-inch ID and 1.5-inch OD.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the mating jig plate bore or liner bushing is clean and dimensionally verified before seating. Disengage all power to the machine and secure the workpiece fixture before removing or installing the bushing. Do not force the bushing into an undersized bore; verify fit class before pressing or sliding into position.
