RUKO Drill Bush Size 09, Ø15.0 mm, DIN 172 A, H7, Tool Steel

In drill jigs and fixtures, precise guidance of twist drills and reamers is critical for repeatable hole accuracy. This RUKO drill bush, size 09 with 15.0 mm inner diameter, provides hardened, ground and lapped surfaces to maintain exact concentricity and alignment during production drilling.

Who is it for

Machinists, toolmakers, and production engineers who build or maintain drill jigs, fixtures, and templates requiring press-fit, replaceable guide bushes for high-precision drilling operations.

Main features

• Plain (headless) design for flush press-fit mounting in jig plates.
