Boneham CB00001177 Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM CB00001177 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built from steel, this renewable bushing carries industry code SF and features a 0.277-inch inside diameter (Letter J) with a close tolerance of +0.0001 to +0.0005 inches, ensuring consistent hole location and concentricity across production runs. The headed design sits flush against the jig plate surface, and LS-1 lock screw compatibility keeps the bushing locked firmly in place under cutting forces. It is installed by machinists and toolmakers in drill jig fixtures across metalworking, fabrication, and general manufacturing environments.

This bushing is suited for headed-style drill jig applications requiring a renewable insert. The slip-fixed configuration allows the bushing to be removed and replaced without disturbing the liner bushing pressed into the jig body, making it practical for fixtures that accommodate multiple drill sizes or require periodic bushing replacement due to wear. The 1-inch length under the head provides adequate guidance for standard drill operations in steel jig plates.

Key Features

• Slip-fixed (SF) industry code design for renewable jig bushing applications
• 0.277-inch (Letter J) inside diameter with +0.0001 to +0.0005-inch tolerance for precise tool guidance
• 0.5-inch body outside diameter fits standard SF-series liner bushings
• 1-inch length under head provides full tool engagement and guidance depth
• Steel construction for durability under repeated drill press and machining cycles
• LS-1 compatible lock screw slot to prevent rotation and axial movement during use

Compatibility

Designed as an OEM-style replacement or production slip-fixed drill bushing compatible with LS-1 lock screws and standard SF-series liner bushings used in drill jig fixtures.

Installation Notes

Slip-fixed bushings are installed and removed by toolmakers or machinists using the appropriate LS-1 lock screw without pressing equipment. Ensure the mating liner bushing bore and the jig plate are clean and free of chips before seating the bushing. Do not force the bushing into a liner with a mallet, as this can damage the tolerance fit. Always verify bushing alignment and lock screw engagement before beginning a drilling operation.
