Bargain 1-7/16″ 4MT Straight Flute Taper Shank Bridge Reamer HSS DWRRBST1-7/16

Industrial-grade reaming tools for precision bore finishing in heavy manufacturing and metalworking environments. The 1-7/16 inch diameter bridge reamer with 4MT taper shank provides reliable alignment and finishing characteristics in machine tool applications.

Specs

Diameter: 1-7/16 inch

Drive type: Morse Taper size 4 (4MT)

Material grade: High Speed Steel

Features

Straight flute design: Facilitates consistent hole finishing and efficient chip evacuation during bore reaming, reducing tool deflection under load.

Bridge reamer geometry: Optimized for trueing bore diameter with controlled chamfer and straight-flute engagement to maintain concentricity with the shank.

Shank compatibility: 4MT taper shank fits standard machine tool spindles and adapters, enabling secure seating and repeatable runout performance.

Wear resistance: High Speed Steel construction provides durability for repetitive finishing tasks across steel, cast iron, and alloy workpieces, with coolant compatibility to extend tool life.

Industrial use cases: Ideal for finishing large-diameter through-holes in automotive housings, hydraulic manifolds, and aerospace components, as well as production-line bore finishing on CNC and manual machines.

Operational guidance: Apply appropriate cutting fluid or coolant, maintain proper spindle alignment, and use fresh, sharp tooling to ensure optimal surface finish and tool life.
