Internal-external pipe reamer Rems 3–35 mm model 113900

Rems internal-external pipe reamer for pipes with diameters from 3 to 35 mm (model 113900) is a handheld tool designed to deburr and ream both inner and outer edges of metal and plastic pipes. It provides consistent edge removal and surface finishing to prepare pipe ends for soldering, brazing, compression fittings or push-fit connections. The compact design allows use in tight spaces common in plumbing and HVAC installations.

Advantages

The reamer integrates inner and outer cutting edges in a single tool, allowing quick transition between internal and external reaming without changing attachments. Hardened cutting surfaces maintain sharpness when used on common pipe materials, and the ergonomic handle offers controlled rotation for uniform chamfering. The tool accommodates a wide diameter range, reducing the need for multiple separate reaming tools.

Suitable for

• Deburring and chamfering copper, steel, stainless steel and plastic pipes
• Preparing pipe ends for soldering, brazing, or mechanical fittings
• On-site plumbing and HVAC installation and repair work
• Workshop pipe preparation and general maintenance tasks

Key specifications

• Pipe diameter range: 3–35 mm
• Functions: internal and external reaming (deburring and chamfering)
• Material compatibility: metal and plastic pipes
• Handheld, manual operation with ergonomic handle

How to use

Select the pipe end and identify whether internal or external deburring is required. Insert the appropriate cutting edge into the pipe bore for internal reaming or position the outer edge around the pipe for external chamfering. Rotate the tool evenly around the pipe axis while applying moderate axial pressure until the burrs are removed and a smooth chamfer is achieved. Inspect the edge and repeat as needed, then clean the pipe surface to remove chips and debris before joining.

Usage recommendations

Use steady, controlled rotations and avoid excessive force to prevent scoring the pipe. For best results on harder materials, perform several light passes rather than aggressive cuts. Keep the tool clean and dry after use and check cutting edges regularly for wear; replace the tool if edges become blunt or damaged.
