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″ (0.13 mm) and less in steel, cast iron, compacted graphite iron, nodular iron, aluminum, bronze and exotic materials.

Higher Penetration Rates and Closer Size Tolerance

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.

Ideally adapted to the sizing and enlarging of previously drilled or cored holes, Star SU valve guide reamers provide higher penetration rates and closer size tolerance.

Star SU valve guide reamer diameters start at .1875″ (4.76 mm). Cutting feeds and speeds are recommended based on the design of the product and the part requirements.

Star SU reamers are made in both multiple flute and multi-diameter types. They can have solid carbide heads brazed to a tubular steel body in sizes up to 2.0″ diameter and with brazed inserts in 2.0″ to 4.0″ diameter ranges.
