Industrial-grade chucking reamer optimized for precision bore finishing in metalworking environments. This High Speed Steel tool is designed for production machining where repeatable hole size and smooth bore surfaces are essential.

Specs

Size: #3

Material Grade: High Speed Steel

Features

Hole finishing accuracy: Finishes drilled holes to final size with a smooth bore finish, reducing rework and improving part quality in high-volume production.

Chucking compatibility: Engineered for use with standard machine tool chucks, enabling quick tool changes and consistent runout control during production milling and drilling.

Wear resistance: High Speed Steel composition offers edge retention and predictable wear characteristics under typical cutting conditions with proper lubrication.

Material versatility: Suitable for common metallic workpieces including carbon steel, alloy steel, stainless steel, and aluminum when used with appropriate feed and coolant strategy.

Use cases: Automotive components, structural members, and industrial equipment housings requiring tight bore tolerances and high surface finish.

Operational guidelines: Apply coolant or cutting fluid and use a conservative feed rate to minimize heat buildup and maintain bore roundness during finishing passes.
