Boneham CB00001310 Slip-fixed Drill Bushing 0.136 in Id

Product Description

The BONEHAM CB00001310 is a slip-fixed drill bushing designed to guide drill bits and other 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 for repetitive drilling operations. It features an inside diameter of 0.136 inches (wire size 29), a body outside diameter of 0.3125 inches (5/16 inch), and a length under head of 0.75 inches (3/4 inch). The head outside diameter measures 35/64 inch with a head height of 1/4 inch. The SF industry code designation identifies it as a slip-fixed type, meaning it is pressed into a liner bushing and secured in position. It is compatible with LS-1 lock screws and meets ANSI standards.

Slip-fixed drill bushings are used in production drilling jigs where a single bushing must remain stationary during the full drilling cycle. This part is suited for machine shops, tool rooms, and manufacturing environments where consistent hole location and tight tolerances are required across high-volume production runs. It is typically installed and serviced by toolmakers, machinists, and precision fabricators working with drill jig assemblies. The renewable design allows the bushing to be replaced without replacing the entire jig body, reducing tooling maintenance costs over time.

Key Features

• Slip-fixed (SF) bushing type — locks into liner bushing via LS-1 compatible lock screw
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Renewable bushing design supports in-place replacement within existing jig fixtures
• Headed configuration with 35/64 inch head OD and 1/4 inch head height for positive seating
• Meets ANSI standards for drill bushing geometry and dimensional accuracy

Compatibility

Designed for use with ANSI-standard liner bushings in slip-fixed drill jig assemblies. Compatible with LS-1 lock screws. Fits jig plates and fixture bodies bored to accept a 5/16 inch body outside diameter bushing.

Installation Notes

Installation is typically performed by a toolmaker or machinist using a bushing press or arbor press to seat the bushing into its liner without damaging the bore. Ensure the jig plate and liner bushing bore are clean and free of chips or burrs before installation. Secure with a compatible LS-1 lock screw to prevent rotation during operation. Do not hammer the bushing directly without a proper driver to avoid distorting the bore or head seating surface.
