Boneham SP00005503 Slip-fixed Drill Bushing 17/32 in Id

Product Description

The BONEHAM SP00005503 is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel and hardened to 60 to 65 HRC, this bushing provides a durable, wear-resistant bore surface for repeated drilling, reaming, or boring operations. The inside diameter measures 17/32 inches with a tolerance of plus 0.0001 to plus 0.0005 inches, ensuring close control over tool guidance. The body outside diameter is 0.75 inches and the length under the head is 1.5 inches. It is compatible with an LS-1 lock screw for positive retention in the liner bushing. This part is installed by machinists, toolmakers, and fixture builders in production and maintenance environments.

This bushing is used in drill jigs and machining fixtures where a removable, locking bushing is required over a installed liner bushing. The slip-fixed design allows the bushing to be installed and locked in place during a machining operation and removed for tool changes or part loading. It is suited for production environments where consistent hole location and tool guidance are critical across repeated part runs. The ANSI-standard industry code SF designation confirms it meets recognized dimensional standards for interchangeability.

Key Features

• Steel construction hardened to 60 to 65 HRC for long service life in abrasive drilling and reaming applications
• Inside diameter of 17/32 inches with plus 0.0001 to plus 0.0005 inch tolerance for precise tool guidance
• Body outside diameter of 0.75 inches fits standard SF-series liner bushings
• 1.5 inches length under head provides adequate tool guidance depth for typical jig plate thicknesses
• LS-1 lock screw compatibility allows secure retention and quick removal without special tooling
• Renewable bushing design — replaceable without disturbing the liner or jig plate
• Meets ANSI standards for SF bushing industry interchangeability

Compatibility

Designed as an OEM-style replacement or direct-fit slip-fixed drill bushing conforming to ANSI SF industry standards, compatible with standard SF liner bushings and LS-1 series lock screws.

Installation Notes

Installation is performed by machinists or toolmakers during jig setup or bushing replacement. The liner bushing must be fully seated in the jig plate before installing this slip-fixed bushing. Rotate the bushing to align the lock screw slot, then thread in the LS-1 lock screw to secure it against rotation and withdrawal during the machining cycle. Inspect bore condition and replace the bushing when inside diameter wear exceeds acceptable tool-guidance tolerances.
