Machine Reamer Series — High-Efficiency Solutions for Precision Machining & Indexable Inserts

Achieve 0~+0.005mm diameter tolerance and high process stability for precision hole machining in Aluminum, Stainless Steel, and Cast Iron.

In daily machining, we understand that hole diameter accuracy and surface quality are critical to the final performance of a product. Our Machine Reamer Series is the result of rigorous material selection and process validation. It is designed for high-precision, high-efficiency environments and integrates seamlessly with our broader range of cutting tools and indexable insert solutions for maximum productivity.

Why Choose Our Machine Reamers?

After testing countless tools on-site, we know that few can maintain stability over the long term. Our reamers are manufactured using premium Carbide rods from Japan and Europe and Swiss precision equipment, ensuring a diameter tolerance of 0~+0.005mm.

Whether it is the straight flute MRU714 Series or the left-hand helical flute MRU717 Series, these tools deliver stable performance on CNC machining centers and automatic lathes. They work in tandem with professional indexable inserts to meet diverse machining requirements.

Machine Reamer Series Comparison

Optimizing Performance for Different Conditions

Depending on the specific machining environment, we recommend selecting reamers based on material characteristics:

Structurally, straight flutes are suitable for general-purpose tasks, while helical flutes provide superior surface finish control, particularly in Steel, Stainless Steel, and Cast Iron. When combined with high-performance cutting tools, they significantly improve chip evacuation.

The Advantage of Precision Machining

Based on numerous projects, using our machine reamers effectively reduces hole diameter variance and burr formation while improving roundness and surface smoothness. Especially in Aluminum and Stainless Steel, helical flutes significantly enhance chip removal to prevent clogging, extending tool life—particularly when paired with high-precision indexable inserts for deep-hole applications.

Customization & Expert Solutions

For clients with extremely strict requirements—such as 0.005mm dimensional control or imperial size needs—we provide bespoke solutions. We offer complete cutting parameter recommendations and troubleshooting based on material properties and equipment, ensuring your cutting tools and indexable inserts achieve maximum efficiency.
