Reamer

Reamers are precision finishing tools designed to enlarge and refine pre-machined holes, ensuring they meet strict requirements for size, roundness, and surface quality. Unlike drilling, which focuses on creating the hole, reaming guarantees superior accuracy and finish, making it essential for high-precision assembly and machining processes.

Performance & Functional Advantages

Dohre reamers provide excellent dimensional stability, low roughness, and minimal tolerance deviation. Their optimized cutting geometry and controlled edge sharpness ensure smooth cutting action, reduced vibration, and consistent results even in tight-tolerance machining. They significantly improve hole quality while reducing secondary finishing operations.

Dohre’s Manufacturing Quality

Each Dohre reamer is produced from premium carbide or high-performance tool steel and shaped through advanced CNC grinding technology to achieve precise geometry and balanced performance.

Strict inspection of cutting edges, runout accuracy, and coating adhesion ensures reliability and long tool life across continuous production tasks.

Drill vs Reamer Comparison

Feature	Drill	Reamer
Main Function	Creates the initial hole in the workpiece.	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	General hole-making across industries.	Precision hole-finishing in aerospace, automotive, mold-making, and medical.

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.
