Boneham SF6422NH Slip-fixed Drill Bushing 25/32 in Id

Product Description

The BONEHAM SF6422NH is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to ANSI standards, it features a 25/32 inch inside diameter and a 1 inch body outside diameter, with a 1-3/8 inch length under head. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance required for repeated production drilling operations. The head configuration and renewable design allow it to be removed and replaced without disturbing the fixture plate. Licensed HVAC, machining, and tooling professionals working with drill jigs will find this bushing meets standard slip-fixed SF industry specifications.

The SF6422NH is used in drill jig and fixture setups where accurate hole location and tool guidance are critical. The slip-fixed configuration allows the bushing to be inserted and locked into a liner bushing in the jig plate. This makes it well suited for production and job-shop environments where bushings are changed between operations while maintaining consistent hole geometry. It accepts an LS-2 compatible lock screw to secure it in position during drilling cycles.

Key Features

• Slip-fixed SF industry code configuration for use with standard liner bushings
• Steel construction hardened to 60 to 65 HRC for extended tool life in repetitive drilling
• Inside diameter tolerance of +0.0002 to +0.0006 inches for precise tool guidance
• Renewable bushing design allows in-plate replacement without fixture disassembly
• LS-2 compatible lock screw engagement secures bushing during operation
• Meets ANSI standards for drill bushing dimensions and performance

Compatibility

Designed as an ANSI-standard slip-fixed SF drill bushing compatible with standard liner bushings and LS-2 lock screws in drill jig and fixture assemblies.

Installation Notes

Installation is performed by toolmakers and machining professionals during jig and fixture setup or maintenance. Power down and lock out any associated machinery before installing or replacing bushings in a jig plate. Use the appropriate LS-2 lock screw to secure the bushing flush and perpendicular to the jig plate surface. Inspect the liner bushing bore for wear or damage before seating the replacement slip-fixed bushing.
