High Quality 1-7/16″ 4MT Spiral Flute Taper Shank Bridge Reamer HSS DWRRB1-7/16

The 1-7/16″ 4MT Spiral Flute Taper Shank Bridge Reamer is a precision finishing tool designed for high tolerance bore finishing within industrial components. It combines a taper shank for secure spindle seating with a spiral flute geometry to optimize chip evacuation and surface finish during reaming operations.

Specs

Diameter: 1-7/16″

Drive type: 4MT

Material grade: High Speed Steel

Features

Flute geometry: Spiral flute design provides effective chip removal and smooth cutting action, supporting precise hole finishing at high spindle speeds.

Mounting stability: Taper shank 4MT enables secure seating in compatible spindles, reducing runout and improving hole concentricity.

Material compatibility: Substrate delivers wear resistance and sharpness suitable for tool steel, cast iron, aluminum alloys, and other common engineering materials.

Use case: Ideal for reaming precision holes in tooling, dies, molds, hydraulic components, automotive assemblies, and aerospace hardware where tight tolerances and smooth surface finish are required.

Finish and wear characteristics: High Speed Steel base provides a balance of toughness and hardness for repetitive reaming operations with repeatable results.
