## Long description

External Countersink Cutter GEKO 3–19 mm (40) is a single-tool solution for creating chamfers and removing burrs from external edges of metal, plastic and wood where material compatibility allows. Designed for use with handheld drills and drill presses, this countersink cutter provides adjustable removable countersinking up to 19 mm diameter and is suitable for finishing operations in workshops, repair tasks and mechanical assembly work.
Advantages
The GEKO external countersink cutter combines a compact design with a wide working range, enabling one tool to cover diameters from 3 to 19 mm. It is intended for quick attachment to standard drill chucks and offers repeatable chamfering performance with minimal setup. The cutter’s geometry is optimized for smooth deburring and consistent chamfer profiles across compatible materials.
Suitable for
Deburring external edges on metal components
Creating chamfers for countersunk fasteners or assembly alignment
Finishing plastic and wooden parts where material properties permit
Workshop repair and maintenance tasks with handheld drills or drill presses
Key specifications
Working diameter range: 3–19 mm
Use type: external countersinking and deburring
Compatible tools: handheld drills and drill presses with standard chucks
Material compatibility: metal, plastic, wood (subject to cutter geometry and material hardness)
Design: removable/adjustable cutting element for variable countersink size
How to use
Secure the countersink cutter in the drill chuck according to the drill manufacturer’s instructions, ensuring the cutter is held firmly and concentric. Select an appropriate rotational speed for the workpiece material and feed the cutter to the external edge evenly, applying steady axial pressure. Make one or more light passes until the required chamfer size and surface finish are achieved. Stop periodically to inspect the chamfer and remove swarf or chips from the cutting area.
Usage recommendations
Use appropriate personal protective equipment, such as safety glasses and gloves, and clamp small or thin workpieces securely to prevent movement. Match cutting speed and feed to the workpiece material: lower speeds for hard metals, higher speeds for plastics and softwoods. Replace or sharpen cutting elements if quality of chamfering decreases to maintain consistent results.
