Multi Diameter Cavity Machining Tools

Star SU has perfected a line of cavity/porting tools that allows machining from either a solid or casted core condition. In some cases, these multi-step tools will allow cavity machining in one pass.

Star SU reamers are made in both multiple flute and multi-diameter types. Based on the overall length of the tool required to machine your feature, we can manufacture a solid carbide reamer or braze a solid carbide reamer head to a tubular steel body.

Super Round Tool (SRT)

Super Round Tool (SRT) is an original Star Cutter Company design and build product that offers a unique, patented design combining two tools into one — multiple straight flutes for consistent location and multiple helical flutes to ensure roundness and finish.

Valve Guide Reamers

Star SU valve guide reamers utilize pressurized coolant to force chips ahead of the tool to produce ultra-smooth, ultraprecise holes. They produce holes to tolerance of 0.0005″ (0.013 mm) and less in steel, cast iron, compacted graphite iron, nodular iron, aluminum, bronze and exotic materials.
