Value Collection 210-7807 Bt to Jacobs Taper Adapter

Product Description

The VALUE COLLECTION 210-7807 is a BT to Jacobs Taper adapter designed to connect BT30 taper spindles to JT6 taper tooling. It serves as a mechanical interface in machining setups, allowing drill chucks and other Jacobs Taper-mounted tools to be seated in BT30-style spindles. The adapter features a BT30 outside taper for spindle engagement and a JT6 inside taper for chuck or tool mounting. With a projection of 1.18 inches, it provides a compact connection point suitable for space-constrained setups. Installation is handled by machinists and toolroom technicians during toolholder assembly or chuck replacement operations.

This adapter is used in vertical and horizontal machining centers, drill presses, and CNC equipment equipped with BT30 spindle interfaces. It is a common solution when mounting Jacobs Taper drill chucks onto BT30 spindle toolholders for drilling, reaming, or tapping operations in both production and job-shop environments. The single-piece construction makes it a straightforward drop-in interface between compatible spindle and chuck configurations.

Key Features

• BT30 outside taper for direct engagement with BT30 spindle toolholders
• JT6 inside taper accepts standard Jacobs Taper No. 6 drill chucks and tooling
• 1.18 inch projection for compact toolholder stack height
• Single-piece adapter construction for rigid, direct taper-to-taper connection
• Weighs 0.5 pounds for easy handling during toolholder changes

Compatibility

Designed as a standard replacement and interface adapter for machining setups using BT30 outside taper spindles paired with JT6 inside taper drill chucks or tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and de-energize the machine spindle before seating or removing any toolholder adapter. Ensure both the BT30 spindle bore and the JT6 chuck shank are clean and free of chips or burrs before assembly to maintain proper taper contact. Never drive taper connections together with excessive impact, as this can damage the seating surfaces and affect runout.
