Boneham AM00000844 Slip-fixed Drill Bushing Sfm 19mm Id

Product Description

The BONEHAM AM00000844 is a slip-fixed drill bushing in the SFM industry code series, designed to guide cutting tools accurately through jig plates and fixture bodies. With a 19 mm inside diameter and a 30 mm body outside diameter, this bushing provides precise hole location and tool alignment during drilling, reaming, or boring operations. The 56 mm length under head gives adequate tool guidance depth for medium to thick workpieces. Fabricated for renewable service, it can be pressed in or slipped into a liner bushing without permanent fixture modification. Machinists, toolmakers, and fixture builders install this type of bushing in production and prototype jig setups where repeatable hole placement is critical.

This bushing is suited for use in drill jigs, modular fixturing systems, and production tooling where the SFM slip-fixed configuration is specified. The renewable design allows the bushing to be exchanged during a job run without disturbing the liner or fixture plate. It is appropriate for both job-shop and high-volume manufacturing environments. When a standard SFM series bushing is called out on a fixture drawing or tooling print, this part directly satisfies that specification.

Compatibility

Designed as an OEM-style replacement or direct-specification slip-fixed drill bushing for fixtures and drill jigs requiring an SFM series bushing with a 19 mm inside diameter and 30 mm body outside diameter.

Installation Notes

Installation and removal should be performed by a qualified toolmaker or machinist using proper bushing press or extraction tools. Before servicing any fixture, ensure all machine power is locked out and the workpiece is fully secured. Do not hammer the bushing directly without a proper driver to avoid damage to the bushing bore or the liner. Verify inside diameter, body outside diameter, and length under head against the fixture drawing before installation.
