Practical for workshop versatility, it simplifies blade changes and reduces the need for multiple arbors.

## Long description

Reducer GEKO 7178665 is an arbor adapter designed to convert a saw blade centre bore of 22.2 mm so the same arbor can accept blades with 20 mm, 16 mm and 12.7 mm bores. The adapter set increases compatibility between blades and machines, allowing blades with smaller centre holes to be mounted on spindles or arbors specified for 22.2 mm mounting.
Advantages
The GEKO 7178665 reducer set provides a simple mechanical solution to fit multiple blade diameters on a single 22.2 mm arbor without machining or additional specialised tools. It reduces the need to keep several arbors for different blade bore sizes, helps speed up blade changes and maintains correct concentric mounting when used with compatible blades and spindles.
Suitable for
 Circular saws and table saws with 22.2 mm arbors
 Angle grinders and powered cutting tools using 22.2 mm mounting
 Workshops and hobbyists who use blades with 20 mm, 16 mm or 12.7 mm centre holes

How to use
Select the reducer ring that matches the blade's centre bore (20 mm, 16 mm or 12.7 mm), press the ring into the blade centre hole and mount the blade onto the 22.2 mm arbor as usual. Ensure the reducer sits flush in the blade bore and that all locking nuts or flanges are tightened to the tool manufacturer's recommended torque before operation. Inspect concentricity and runout after installation and before cutting.
Usage recommendations
Use only with blades and machines whose maximum RPM and mounting instructions match the blade and adapter specifications; do not use damaged or deformed reducer rings. Regularly check secure fit and concentricity to prevent vibration and premature blade wear.
