Value Collection 950-12041 Bxa Boring Bar Holder

Product Description

The VALUE COLLECTION 950-12041 is a Number 4 Boring Bar Holder designed for use with BXA series quick-change tool post systems on engine lathes. It accepts boring bars up to 1 inch in diameter and supports a centerline height of 7/8 inches, making it suited for internal turning and boring operations. The holder is compatible with lathes in the 10 to 15 inch swing range and provides a secure, repeatable setup for production and maintenance machining environments. Machinists and toolroom technicians install this holder as part of a BXA quick-change system to reduce setup time between operations.

This boring bar holder fits lathes with a swing of 10 to 15 inches, placing it in the mid-size engine lathe category common in job shops, apprentice training facilities, and industrial maintenance departments. It is intended for use wherever BXA series tool post hardware is already installed. A 3/4 inch boring bar size with bushing option allows the holder to accommodate smaller-diameter bars when a reducing bushing is used, adding versatility for shops running varied internal bore diameters.

Installation Notes

Installation is performed by a machinist or toolroom technician familiar with lathe tooling setups. Power down and lock out the lathe before mounting or removing any tool post holder. Secure the boring bar firmly in the holder using the appropriate clamping screws before resuming spindle operation. Verify tool centerline height alignment against the lathe spindle centerline prior to taking a cut.
