Boneham P5612LZ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P5612LZ is a headless press fit drill bushing designed to guide drill bits and other cutting tools with precision during machining operations. Manufactured from steel, this Type P bushing measures 37/64 inches inner diameter, 7/8 inches outer diameter, and 3/4 inches overall length. The press fit installation method means the bushing is driven directly into the jig plate and remains fixed during use, providing consistent hole location accuracy without a locking head. It is used by machinists, tool and die makers, and precision fabricators wherever repeatable hole positioning is required.

This bushing is suited for drill jig applications in production and prototype machining environments. The headless design sits flush with the jig plate surface, making it appropriate for close-clearance setups where a headed bushing would interfere with workpiece clamping or tooling. It is a non-renewable bushing, meaning it is pressed in permanently rather than designed for routine field replacement. Typical installation is performed during jig assembly or maintenance by toolmakers working with a drill press, arbor press, or similar equipment.

Key Features

• Type P headless design sits flush with jig plate surface for close-clearance applications
• Press fit installation method secures bushing permanently without a locking head or retaining collar
• 37/64 inches ID with a tight inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for accurate tool guidance
• Steel construction provides durability and wear resistance in repetitive drilling operations
• Non-renewable, fixed-position bushing suited for permanent jig assemblies
• Compact 3/4 inches overall length fits standard jig plate thicknesses

Compatibility

Designed as a standard Type P headless press fit drill bushing for use in drill jig plates requiring a 7/8 inches OD pressed bore and a 37/64 inches tool bore.

Installation Notes

Installation is typically performed by a toolmaker or machinist using an arbor press or hydraulic press. The receiving bore in the jig plate must be machined to the correct press fit tolerance before installation. Once pressed in, this bushing is not designed for removal and reuse. Verify bore alignment and bushing seating before placing the jig into production service.
