Boneham AM00000843 Slip-fixed Drill Bushing Sfm 19mm Id

Product Description

The BONEHAM AM00000843 is a slip-fixed drill bushing conforming to the SFM industry standard. It features an inside diameter of 19 mm, a body outside diameter of 30 mm, and a length under head of 45 mm. This bushing is designed to guide cutting tools accurately during drilling operations, providing a hardened, renewable wear surface inside a jig plate or fixture body. Machinists and tooling engineers install this type of bushing in production drill jigs where repeatable hole location and tool guidance are critical to maintaining part quality and dimensional consistency.

Slip-fixed bushings in the SFM configuration are used in drill jig applications across metalworking and manufacturing environments. The slip-fixed design allows the bushing to be locked in place during a drilling operation and removed when the jig is not in service, making it well suited for operations where chip clearance or tool changes require bushing removal between cycles. This part is a renewable bushing, meaning it can be replaced independently of the jig liner, extending the service life of the overall fixture assembly.

Key Features

• SFM industry code conformance for standardized slip-fixed bushing interchangeability
• 19 mm inside diameter for precise cutting tool guidance
• 30 mm body outside diameter for secure seating in the jig liner
• 45 mm length under head to accommodate workpiece thickness and chip clearance requirements
• Renewable bushing design allows field replacement without replacing the press-fit liner

Compatibility

Designed as a standard SFM-type slip-fixed drill bushing for use with compatible SFM press-fit liners in production drill jig fixtures requiring a 19 mm tool bore.

Installation Notes

Slip-fixed bushings are installed and removed by hand or with a bushing puller tool; no pressing equipment is required for the bushing itself, though the mating liner must already be properly seated in the jig plate. Ensure the jig plate and workpiece are securely fixtured before engaging the cutting tool. Always verify the bushing ID is matched to the cutting tool or tool holder diameter before use. Replace the bushing when inside diameter wear exceeds allowable tolerance for the application.
