Specs

Dimensions: Diameter 1-1/4″

Material grade: High Speed Steel

Features

Straight flute geometry: Maintains axial alignment and reduces bore wander during manual enlargement.

Manual operation: Designed for hand reaming with standard tooling; no power drive required.

Surface finish: Produces a smooth bore with minimal burr formation when used with proper lubrication and controlled feed.

Material compatibility: Suitable for steel, cast iron, and common industrial alloys encountered in machined housings and blocks.

Durability: High Speed Steel construction offers edge retention for multiple reaming passes in typical workshop cycles.

Use cases: Ideal for enlarging predrilled holes to achieve precise pin fitment, alignment features, or bore refinement in assembly components.
