Boneham P1312BT Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P1312BT is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing features a 0.0635-inch inside diameter corresponding to a No. 52 wire gauge drill size, a 13/64-inch body outside diameter, and a 3/4-inch overall length. It installs without a head flange, making it suited for applications where a flush or below-surface profile is required. The inside diameter holds a tolerance of positive 0.0001 to positive 0.0004 inches, ensuring consistent, repeatable hole location across production runs. This is a non-renewable style bushing intended for permanent press fit installation in drill jig plates.

This bushing is used in precision drilling, reaming, and boring operations in manufacturing, toolroom, and production environments. Its headless design allows use in close-spacing layouts and in situations where multiple bushings must be positioned without interference. The counterbored body configuration accommodates specific jig plate setups where additional clearance or seating depth is needed. Machinists, toolmakers, and fixture builders working in metalworking and fabrication shops will encounter this part as a standard component in drill jig assemblies.

Key Features

• Industry code P bushing with press fit installation — no locking mechanism required
• 0.0635-inch inside diameter fits No. 52 wire gauge drill size
• Inside diameter tolerance of positive 0.0001 to positive 0.0004 inches for accurate tool guidance
• Headless design provides flush or sub-flush seating in drill jig plates
• Counterbored body for precise seating depth in compatible jig plate bores
• Steel construction for durability in repetitive drilling operations

Compatibility

Designed as an OEM-style replacement or direct-use drill jig component for press fit headless bushing applications requiring a No. 52 wire gauge inside diameter and a 13/64-inch outside diameter per industry standard P-series bushing specifications.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The jig plate bore must be machined to the appropriate interference fit tolerance before pressing the bushing into place. This is a non-renewable bushing and is not designed for removal and reinstallation. Verify that the bushing is fully seated and square to the jig plate surface before putting the fixture into service.
