Clearance 1/2″ Straight Shank Expansion Reamer HSS DWRRE1/2

Industrial expansion reamers are precision cutting tools used to enlarge and finish cylindrical bores with tight tolerances. This product combines a straight shank with high speed steel construction to deliver reliable performance in metalworking and fabrication environments.

Specs

Nominal size: 1/2″

Drive type: Straight shank

Material grade: High Speed Steel (HSS)

Features

Precise bore expansion: Enables final bore diameter control within tight tolerances for production fixtures and assemblies.

Adjustable diameter mechanism: Allows incremental adjustments to hole size without switching tools, reducing setup time in job shops.

Straight shank compatibility: Fits standard toolholders, chucks, and collets, minimizing runout and improving surface finish.

Material performance: High Speed Steel provides wear resistance and heat tolerance suitable for die, mold, and general metalworking operations.

Use cases: Hydraulic cylinder bores, OEM component housings, precision alignment features, and fixture work requiring accurate hole sizing.

Production durability: Designed for repeated reaming cycles in high-output environments with consistent results.
