Boneham CB00001226 Slip-fixed Drill Bushing 0.204 in Id

Product Description

The BONEHAM CB00001226 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built from steel, it features a 0.204 inch inside diameter and a 0.5 inch body outside diameter with a 1 inch length under the head. The head-style design seats flush against the jig plate and is secured in place with an LS-1 compatible lock screw, preventing rotation during operation. Inside diameter tolerance is held to +0.0001 to +0.0004 inches, making it suitable for applications that demand close positional accuracy. It is classified under bushing industry code SF and carries UNSPSC code 31171603. Installed by tool-and-die makers, jig builders, and production machinists.

This bushing is used in drill jig fixtures across production and maintenance machining environments. The renewable design allows the bushing to be removed and replaced without disturbing the jig plate, reducing downtime on repetitive drilling operations. Typical applications include close-tolerance hole location in steel and cast-iron workpieces where consistent drill entry point and perpendicularity are required. The LS-1 lock screw compatibility ensures the bushing is positively retained in the jig liner during high-cycle operations.

Key Features

• Slip-fixed (SF) bushing industry code for use with standard drill jig liners
• 0.204 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches
• Renewable bushing design allows in-place replacement without jig disassembly
• Head-type construction with 51/64 inch head outside diameter and 1/4 inch head height
• LS-1 compatible lock screw seat secures bushing against rotation and axial movement
• Steel construction for durability in production drilling environments

Compatibility

Designed as an OEM-style replacement slip-fixed drill bushing for use with LS-1 lock screws in standard drill jig liner assemblies.

Installation Notes

Installation is typically performed by machinists or tool-and-die professionals during jig setup or bushing replacement. The jig fixture must be fully secured and all spindle drives powered down before removing or seating a drill bushing. Use the appropriate lock screw driver to engage the LS-1 compatible set screw after the bushing is fully seated in its liner. Verify inside diameter clearance against the intended drill or reamer shank before production use.
