About the Press-Fit Drill Bushing, 3 mm ID
Press-fit drill bushings are pressed permanently into a fixture-plate hole sized slightly smaller than the bushing body, so drill bits and other cutting tools are guided precisely while the plate itself is protected from wear. This Press-Fit Drill Bushing 3 mm ID is a headless metric bushing with a 6 mm outside diameter and 12 mm length, catalogued under supplier reference 8486A25. Being headless, it can be pressed flush with — or below — the fixture-plate surface, allowing the workpiece to sit directly against the plate and letting the bushing be located anywhere in the plate thickness. The 12 mm length provides generous guidance for a 3 mm drill, four bore-diameters of support that helps the drill enter on location without wandering. McMaster-Carr lists its metric press-fit drill bushings as hardened, ground steel, so the bore resists wear and keeps hole position repeatable over long fixture service. Installation is by manual or hydraulic press into an interference-fit hole.

Typical applications
Choose this bushing for jig plates around 12 mm thick that must guide 3 mm drills flush with the plate face — for instance templates for tapping-size holes ahead of M3-class fasteners in brackets and enclosures. The flush headless form suits fixtures where the workpiece must clamp flat against the plate without a protruding shoulder.
