Boneham PT2412GB Headless Drill Bushing 0.199 in Id Steel

Product Description

The BONEHAM PT2412GB is a press fit headless drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. Carrying the industry code P, this bushing features a 0.199 inch inside diameter and a 3/8 inch outside diameter. It presses directly into a jig plate without a head flange, keeping the top surface flush for applications where a low-profile seating is required. Machined from steel and hardened to 60 to 65 HRC, the PT2412GB delivers the wear resistance needed for repetitive, high-cycle production drilling work in metalworking and fabrication environments.

This bushing is intended for use in drill jigs and fixture plates where precise hole location and tool guidance are critical. The headless, non-renewable design suits permanent installations in jig plates used in general machining, toolroom, and production floor settings. At 3/4 inch overall length, it provides adequate tool guidance depth for standard drill diameters in the No. 8 wire gauge range. Machinists, toolmakers, and fixture builders are the primary installers of this component.

Key Features

• Press fit installation method for a secure, permanent seat in the jig plate bore
• Headless design creates a flush top surface suitable for low-clearance fixture setups
• Steel construction hardened to 60 to 65 HRC for high wear resistance under repeated tool passes
• Inside diameter tolerance of +0.0001 to +0.0004 inches ensures consistent tool guidance
• Conforms to ANSI standards for drill bushing geometry and fitment
• Non-renewable configuration suited for fixed, long-run jig applications

Compatibility

Designed as a press fit headless drill bushing conforming to ANSI standards, suitable for installation in drill jig plates requiring a P-code headless bushing with a 0.199 inch ID and 3/8 inch OD.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press to drive the bushing flush into a precisely bored jig plate hole. Ensure the receiving bore in the jig plate is sized to the appropriate interference fit per ANSI specifications before pressing. Do not hammer the bushing directly without a proper pressing tool, as this can cause misalignment or damage to the bore. Once pressed in, this bushing is not intended to be removed and reused.
