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.
| Series | Increment | Material | Flute Style | Hole Type | Recommended Materials | Applications |
|---|---|---|---|---|---|---|
| MRU714 | 0.01mm | Japanese Carbide | Straight | Through Hole | General Purpose | Optimized for CNC Machining Centers |
| MRU717 | 0.01mm | Japanese Carbide | LH Helical | Through Hole | General & Steel (Best) | Short flute; for Automatic Lathes & CNC Centers |
| MRU607 | 0.5mm | European Carbide | LH Helical | Through Hole | General & Steel (Best) | Optimized for CNC Machining Centers |
| MRU777 | 0.01mm | HSSE-Co (Japan) | LH Helical | Through Hole | Unheated Mat. (HRC<20) | Unstable conditions; Low-medium speeds. Automatic Lathes & CNC |
Diverse Material & Structural Options
Optimizing Performance for Different Conditions
Depending on the specific machining environment, we recommend selecting reamers based on material characteristics:
- Solid Carbide Reamers: Superior wear resistance with a lifespan 5–10 times longer than HSS; ideal for medium-to-high speed cutting.
- HSSE-Co (Cobalt HSS) Reamers: Economical and durable for unstable machining environments or low-to-medium speed operations.
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.
