Boneham AM00000931 Slip-fixed Bushing Sfm 4.3mm Id

Product Description

The BONEHAM AM00000931 is a slip-fixed drill bushing with an SFM industry code, designed to guide cutting tools with precision during machining and drilling operations. It features a 4.3 mm inside diameter and a 10 mm body outside diameter, with a 25 mm length under the head. The slip-fixed design allows the bushing to be inserted and locked in place within a jig plate, providing repeatable hole location accuracy. This bushing is renewable, meaning it can be replaced independently of the jig body when worn. Installation is performed by machinists, toolmakers, and fixture builders working in production or repair environments.

This bushing is suited for use in drill jigs and fixture tooling where guided hole drilling is required. The SFM bushing type is a standard industry configuration commonly specified in tooling plates for light to medium production runs. The renewable feature makes it a practical choice for fixtures that see regular use and periodic bushing replacement without retiring the entire jig assembly.

Key Features

Compatibility

Designed as an OEM-style replacement or production bushing for standard drill jigs and fixture tooling requiring SFM-type slip-fixed renewable bushings.

Installation Notes

Installation is typically performed by a machinist or toolmaker. The bushing slips into a compatible headless liner and is locked with a lock screw to prevent rotation during drilling. Ensure the jig plate and liner bore are clean and free of chips before installation. Follow applicable shop safety procedures and de-energize any powered fixtures before servicing bushing components.
