Industrial-grade reaming tools for precision bore finishing in high-demand manufacturing environments. The 1 inch diameter, 3MT Straight Flute Car Reamer is engineered from High Speed Steel to deliver consistent hole geometry and extended tool life in automotive, aerospace, and heavy equipment machining.

Key attributes include 3MT shank, Straight Flute geometry, and High Speed Steel construction for wear resistance and long tool life. The design supports clean break-in and controlled material removal in automotive engine blocks, transmission housings, and hydraulic components where bore finish and straightness are critical.

Recommended usage emphasizes stable workholding, appropriate lubrication, and consistent speeds and feeds to optimize surface finish and dimensional accuracy. Ideal for finishing cylinder bores and related features after rough drilling in high production environments, this tool helps maintain bore roundness and compatibility with subsequent installation of liners, sleeves, or other cylindrical components.
