Reamers are precision tools developed specifically for finishing and sizing pre-machined holes. Unlike drilling, which focuses on creating the hole, reaming ensures that the hole reaches the required dimensional accuracy, roundness, and fine surface quality. Dohre reamers are designed to provide stable cutting performance, reduce tolerance deviations, and minimize roughness for superior hole processing results.
With strict control over tool geometry, edge sharpness, and surface coating, our reamers are suitable for a wide range of materials, from steel and stainless steel to non-ferrous metals. Whether for high-speed machining lines or precision assembly components, Dohre reamers help manufacturers achieve high consistency and efficiency in hole finishing.
Enlarges and finishes pre-drilled holes to exact size.
Dimensional Accuracy
Moderate, tolerance usually higher.
Very high, capable of tight tolerances (e.g., H7, H8).
Surface Finish
Rougher finish, may require further machining.
Smooth finish with excellent roundness and straightness.
Material Removal
Removes a larger amount of material quickly.
Removes only a small amount of material to refine accuracy.
Cutting Speed
Higher cutting speed for faster hole creation.
Lower cutting speed for controlled and stable cutting.
Tool Life
Shorter when used for precision finishing.
Longer life in finishing applications due to light material removal.
Applications

Dohre Reamer Avdantages
Exceptional Dimensional Accuracy
Our reamers are manufactured with ultra-precise grinding to ensure consistent hole sizes and minimal tolerance variations. This accuracy guarantees better assembly performance and reduces the risk of rework.
Smooth Surface Finish
Special edge geometry and optimized cutting parameters allow Dohre reamers to deliver holes with fine finishes, reducing friction and improving the lifespan of mating components.
Optimized Tool Life
With advanced carbide substrates and high-performance coatings, our reamers resist wear and maintain cutting stability, even in demanding production environments. This results in longer tool life and fewer tool changes.
Efficiency in Mass Production
Stable performance, fast cutting speeds, and reliable repeatability make our reamers highly suitable for automated and high-volume machining lines, helping customers achieve cost savings and consistent product quality.
Reamer FAQ
What is the main purpose of a reamer?
A reamer is designed for finishing and sizing pre-drilled holes, ensuring high dimensional accuracy, roundness, and smooth surface quality.
What materials can Dohre reamers process?
Our reamers can be used for steel, stainless steel, cast iron, aluminum, copper alloys, and hardened steel, depending on the tool material and coating selection.
What is the difference between HSS and carbide reamers?
HSS reamers are cost-effective and suitable for general machining, while carbide reamers provide higher wear resistance, stability, and performance for high-speed or mass production.
Can reamers achieve tighter tolerances than drills?
Yes. Reamers are specifically designed to correct hole size deviations and improve surface finish, often reaching tighter tolerances than standard drilling.
How can I choose the right reamer for my application?
Selection depends on the workpiece material, required tolerance, surface finish, and production volume. Our technical team can recommend the most suitable reamer for your needs.
What materials can DOHRE reamers machine?
DOHRE reamers are suitable for a wide range of materials, including carbon steel, alloy steel, stainless steel, cast iron, aluminum, and high-performance alloys.
