Boneham SF206DE Slip-fixed Drill Bushing 0.104 in Id Steel

Product Description

The BONEHAM SF206DE is a slip-fixed drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Built from steel with a hardness of 60 to 65 HRC, this SF-series bushing features a 0.104 inch inside diameter (wire size number 37) and a 0.3125 inch body outside diameter. The inside diameter tolerance is held to +0.0001 to +0.0004 inches, ensuring consistent hole location across repeated operations. The head-style design and renewable construction make it suitable for production drilling environments where bushing replacement is part of routine maintenance. Machinists, tool and die makers, and fixture builders are the primary installers.

This bushing is used in drill jigs and machining fixtures where guided drilling, reaming, or boring operations require repeatable accuracy. The slip-fixed configuration allows the bushing to be seated and secured in a jig plate liner bushing using an LS-1 compatible lock screw. The 0.375 inch length under head accommodates standard jig plate thicknesses in light to medium production setups. The renewable design means the bushing can be replaced without disturbing the liner bushing already pressed into the fixture plate, reducing downtime between production runs.

Key Features

• SF-series slip-fixed bushing with head for positive seating in liner bushings
• 0.104 inch inside diameter (wire gauge number 37) with tight tolerance of +0.0001 to +0.0004 inches
• Steel construction hardened to 60 to 65 HRC for wear resistance under repeated tool contact
• Renewable design allows bushing replacement without removing the liner from the fixture plate
• Compatible with LS-1 lock screw for secure, rotation-resistant seating
• Meets ANSI standards for drill bushing dimensions and interchangeability

Compatibility

Designed for use with LS-1 compatible lock screws and standard ANSI-dimensioned liner bushings in drill jig and fixture applications. Conforms to ANSI slip-fixed bushing standards for dimensional interchangeability.

Installation Notes

Installation is typically performed by machinists or tool and die makers during fixture setup or bushing replacement. The fixture plate and any associated tooling should be fully de-energized and secured before bushing service. Insert the bushing into the liner bushing and rotate to align the head notch with the lock screw, then secure with an LS-1 compatible screw. Do not force or hammer the bushing into the liner, as this can damage the bore or alter inside diameter tolerance.
