Rohrentgrater EK Water Blocks EK-HD Tube Reamer

The EK-HD Tube Reamer is an external and internal tube reamer designed to remove burrs and rough edges from freshly cut tubing. Constructed from plastic and steel, the tool accommodates tubes with a minimum inner diameter of 5 mm and a maximum outer diameter of 30 mm, and is intended primarily for use with acrylic, PETG, copper, aluminum, brass, and carbon fiber tubing used in liquid cooling systems.

Advantages

The reamer provides both internal and external deburring in a single tool, enabling clean, concentric tube ends. Its combination of durable plastic and steel parts offers a balance of lightweight handling and structural strength. The design supports a wide range of common tubing materials used in PC water-cooling applications and helps prepare tube ends for better fittings and seals.

Suitable for

• Deburring and finishing freshly cut acrylic and PETG tubes
• Preparing copper, aluminum and brass tubing ends
• Working with carbon fiber tubing (external and internal finishing)
• Tube preparation in custom liquid cooling loop assembly and maintenance

Key specifications

• Supported tube inner diameter: from 5 mm
• Supported tube outer diameter: up to 30 mm
• Function: internal and external reaming (deburring and finishing)
• Materials compatibility: acrylic, PETG, copper, aluminum, brass, carbon fiber
• Construction: plastic body with steel working parts

How to use

After cutting the tube to length, insert the appropriate end into the internal reamer and rotate the tool to remove internal burrs. For external finishing, place the external part of the tool over the tube end and rotate to smooth the outside edge. Repeat as needed until the cut edge is even and free of roughness. Inspect the tube end visually and by feel before installing fittings.
