Star Cutter’s family of reamer products is engineered to improve hole quality, accuracy, and overall machining efficiency. Designed for CNC and production environments, these custom carbide reamers utilize optimized geometries, coolant strategies, and advanced coatings to deliver consistent performance across a wide range of applications.
Ideally suited for enlarging existing hole conditions, Star Cutter pressure‑coolant reamers are custom‑designed with strategic coolant passages, optimized flute configurations, and specialized coatings to enhance tool performance and deliver superior results.
This unique, patented design combines two tools into one, featuring multiple straight flutes for consistent location and multiple helical flutes to ensure exceptional roundness and surface finish. Our products deliver micron level accuracy across a wide range of applications, including powdered metal, all iron materials, and more. The SRT offers:
Star Cutter valve guide reamers utilize pressurized coolant to force chips ahead of the tool, producing ultrasmooth, ultraprecise holes in powdered metal and cast iron. Star Cutter valve guide reamers provide higher penetration rates and closer size tolerances.
Our advanced engineering group works hand in hand with valve guide material manufactures R&D centers to optimize our tooling designs to ensure the machinability based on the guide material grade machined. Cutting feeds and speeds are recommended based on the design of the product and the part requirements.
Star Cutter Company has developed into a world leader in the cutting tool industry. Each of our six manufacturing facilities specializes in producing a specific type of product or service: solid carbide cutting tools, carbide blanks and preforms, gundrills, gear cutting tools, and 5-axis CNC tool and cutter grinding machines.
