Value Collection SC05879812 Type Z Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879812 is a Type Z rotary tool holder bushing designed for use in drill press and milling machine tooling setups. It features a 0.75-inch inside diameter and a 1.5-inch outside diameter, with a length under head of 3.25 inches and a slot length of 2.875 inches. The head thickness measures 0.75 inches. This bushing is used to locate and support cutting tools, drill bits, or tool shanks within a tooling block or jig plate, providing accurate alignment and reducing runout during machining operations. Installation is typically performed by machinists and toolroom technicians.

This Type Z bushing is suited for precision tooling applications in both manual and CNC-assisted machine shop environments. It fits standard tool holder blocks and jig bushings where a slotted, press-fit or slip-fit retention style is required. The slot accommodates a locking pin or drive key, securing the bushing in place under rotational load. It is appropriate for light to moderate-duty drilling, reaming, and boring operations in production and maintenance machining contexts.

Key Features

• Type Z bushing style with slotted head for keyed or pin-lock retention
• Inside diameter of 0.75 inches for standard 3/4-inch shank tooling
• Outside diameter of 1.5 inches for standard tool holder block seating
• Length under head of 3.25 inches provides extended tool support depth
• Slot length of 2.875 inches accommodates standard drive key engagement
• Head thickness of 0.75 inches for positive axial seating against the jig plate

Compatibility

Designed as an OEM-style replacement or standard toolroom component for Type Z rotary tool holder bushing applications requiring a 0.75-inch inside diameter and 1.5-inch outside diameter seating.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the tool holder block or jig plate bore is clean and free of burrs before seating the bushing. Power down and lock out all machine tools before installing or removing bushings. Do not force the bushing into an undersized bore; verify bore tolerance compatibility before pressing.
