Boneham AM00000946 Slip-fixed Drill Bushing Sfm

Product Description

The BONEHAM AM00000946 is a slip-fixed drill bushing with an SFM industry code, designed to guide cutting tools accurately during drilling, reaming, and boring operations. The bushing features a 4.7 mm inside diameter, a 10 mm body outside diameter, and a 25 mm length under the head. It installs into a jig plate using a slip-fixed installation method, allowing the bushing to be held in place by a lock while remaining removable for tool changes or replacement. Machinists and tooling specialists working with drill jigs and fixture tooling are the primary users of this component.

This bushing is suited for use in drill jig applications where accurate hole location and repeatability are critical. The slip-fixed configuration is commonly specified when a bushing must be exchanged during a multi-operation sequence - for example, swapping from a drill bushing to a reamer bushing at the same station. It is appropriate for light to medium production tooling in both job shop and manufacturing environments where SFM-style bushings are called out on fixture drawings.

Key Features

• SFM industry code slip-fixed installation method for secure, removable positioning in jig plates
• 4.7 mm inside diameter provides precise tool guidance for drilling and reaming operations
• 10 mm body outside diameter for compatibility with standard SFM liner bushings
• 25 mm length under head accommodates tooling setups requiring adequate guide length
• Renewable bushing design allows replacement without replacing the full jig assembly

Compatibility

Designed as an OEM-style replacement or new-installation slip-fixed drill bushing conforming to SFM industry standards for use in standard drill jig fixtures accepting SFM-style liner bushings.

Installation Notes

Slip-fixed bushings are installed and removed by a qualified machinist or tooling technician using the appropriate bushing lock. Ensure the mating liner bushing and lock are free of debris and in serviceable condition before installation. Secure all workholding and deactivate any automated feed equipment before exchanging bushings mid-operation. Follow applicable shop safety procedures and fixture manufacturer specifications for proper seating and lock engagement.
