Tube Reamer/Calibrator GEKO 20-25-32 mm model 125

GEKO Tube Reamer/Calibrator model 125 is a handheld tool designed to deburr, chamfer and calibrate tube ends for diameters 20 mm, 25 mm and 32 mm. The tool combines reaming and calibration functions to prepare pipe ends for cleaner joins and better fitment in plumbing, HVAC and light metalworking applications. Its compact design and dedicated size settings allow consistent results on plastic and metal tubing within the specified diameter range.

Advantages

The GEKO calibrator provides a straightforward way to remove burrs and create uniform chamfers on tube ends without the need for separate tools. It ensures repeatable calibration results for the three supported diameters, reducing assembly time and improving joint quality. The tool's ergonomic handle and simple operation make it suitable for on-site use and confined spaces. Materials and cutting geometry are designed to balance cutting efficiency with ease of use.

Suitable for

• Preparing pipe ends for soldering, brazing or mechanical fittings in plumbing work
• Deburring and chamfering tubing for HVAC installations
• Light metalworking tasks involving small-diameter tubes
• Field service and maintenance where quick tube end preparation is needed

Key specifications

• Supported tube diameters: 20 mm, 25 mm, 32 mm
• Functions: reaming (deburring) and calibration (chamfering)
• Handheld manual operation suitable for on-site use
• Compact, single-piece body with ergonomic handle for controlled operation
• Suitable for plastic and common metal tubes within specified diameters

How to use

Select the appropriate diameter setting and insert the tube end into the corresponding opening. Rotate the tool around the tube or rotate the tube against the cutter with steady pressure to ream out burrs and form a consistent chamfer. Inspect the tube end visually and by fit test with the intended fitting; repeat the operation if additional material removal or smoothing is required. Clean the tool and the prepared tube end after use to remove chips and debris.

Usage recommendations

Use personal protective equipment such as gloves and eye protection when reaming or calibrating tubes. Avoid excessive force to prevent deforming softer tubes; perform gradual passes until the desired finish is achieved. Keep the tool clean and store it dry to maintain cutting performance.
