Reamer 4EH7 12.0xD12x75

Description

Reamer 4EH7 12.0xD12x75 is a precision solid carbide finishing tool designed for producing highly accurate and smooth internal holes in CNC and conventional machining operations. With a 12 mm cutting diameter, 12 mm shank, and 75 mm overall length, this reamer offers excellent rigidity and concentricity, ensuring stable cutting performance and consistent hole geometry.

The H7 tolerance grade allows this reamer to achieve tight dimensional control, making it ideal for applications where exact hole size, roundness, and surface finish are critical. The 4-flute cutting geometry provides balanced cutting forces and efficient chip evacuation, reducing vibration and preventing chatter during high-speed machining. This results in improved bore quality and longer tool life.

Manufactured from high-quality solid carbide, the reamer delivers excellent wear resistance, heat stability, and edge retention, allowing it to perform reliably in steels, stainless steel, alloy steel, and medium-hard materials. It is widely used in die and mould manufacturing, auto component machining, jigs and fixtures, precision mechanical parts, and CNC machining centers.

The 12 mm shank ensures strong clamping in tool holders, minimizing run-out and improving bore accuracy. Whether used for finishing drilled holes or improving bore geometry, the Reamer 4F H7 12.0×D12×75 ensures high productivity, reduced tool changes, and superior surface finish in demanding industrial environments.
