Boneham SFT168DV Slip-fixed Drill Bushing Steel 1/8 in Id

Product Description

The BONEHAM SFT168DV is a slip-fixed (SF) drill bushing used in jig and fixture tooling to guide cutting tools with precision and repeatability. It features an inside diameter of 0.125 inches with a tight tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 0.250 inches, and a length under head of 0.500 inches. Constructed from steel, it is a renewable bushing design — meaning it can be replaced in the liner without disturbing the jig plate. Installation and removal are performed by machinists and toolmakers during fixture setup and maintenance operations.

This bushing is suited for use in drill jigs and production tooling fixtures where guided hole operations — drilling, reaming, or boring — require consistent positional accuracy across repeated cycles. The headed design seats against the jig plate face for positive axial location. Its renewable configuration makes it appropriate for high-cycle production environments where bushing wear is expected and scheduled replacement is part of standard toolroom maintenance practice.

Key Features

• Inside diameter of 0.125 inches held to a +0.0001 to +0.0004 inch tolerance for precise tool guidance
• Body outside diameter of 0.250 inches with a head outside diameter of 0.4375 inches
• Length under head of 0.500 inches; head height of 0.250 inches
• Steel construction for durability in repetitive jig fixture applications
• Renewable bushing design allows field replacement without jig plate rework
• Compatible with LS-TW-2 lock screw for secure retention in the liner bushing

Compatibility

Designed for use with LS-TW-2 compatible lock screws. Fits standard SF-style liner bushings sized to accept a 0.250 inch body outside diameter renewable bushing.

Installation Notes

Installation of drill bushings is typically performed by toolmakers or machinist-level technicians during jig assembly or bushing replacement cycles. The bushing should be pressed or slip-fitted into the appropriate liner bushing by hand; do not strike the head directly with a hammer. Secure with the compatible LS-TW-2 lock screw to prevent rotation or axial movement during cutting operations. Verify inside diameter clearance against the intended drill or reamer shank before placing the jig into production.
