Adapter reducers for discs GEKO set of 4 (G00195) for power tool cutting/grinding discs

Set of four GEKO adapter reducers designed to adapt cutting and grinding discs with smaller centre holes to power tools with larger spindles. These metal reducers provide accurate centring and stable attachment of discs, reducing runout and ensuring reliable rotation during cutting, grinding or sanding operations. The set is intended for workshop, metalworking, construction and DIY use where disc-to-arbor compatibility is required.

Advantages

The adapter reducers are made of durable metal to withstand rotational forces and repeated mounting. Supplied as a set of four, they cover common disc-to-arbor conversion needs and enable fast installation and removal without additional tools. Their precise bore and flange surfaces promote concentric mounting, which helps reduce vibration and uneven wear of discs. The compact design keeps the reduction distance minimal, maintaining tool balance and performance.

Suitable for

• Adapting cutting discs to grinders with larger spindles
• Using grinding or flap discs with incompatible centre hole diameters
• Workshop and metal fabrication tasks requiring secure disc mounting
• Renovation, construction and general DIY cutting or grinding jobs

Key specifications

• Quantity: set of 4 reducers
• Material: metal construction for strength and wear resistance
• Purpose: centre-hole reduction for cutting and grinding discs
• Compatibility: fits discs with smaller centre holes to tools with larger spindles (check spindle and disc hole sizes before use)
• Design: low-profile flange to maintain balance and reduce runout

How to use

Select the reducer that matches the disc centre hole and the tool spindle. Place the reducer into the disc centre hole, align the disc on the tool spindle and mount the disc assembly following the tool manufacturer’s spindle nut or clamping instructions. Ensure the reducer sits flush in the disc hole and the disc is properly centred before tightening. After mounting, manually rotate the disc to check for wobble or misalignment and re-seat if necessary. Regularly inspect reducers for wear or deformation and replace if damaged.

Usage recommendations

Use the adapter reducers only with discs and tools rated for the operational speed of your power tool. Always follow the disc and tool manufacturer safety instructions, wear appropriate personal protective equipment, and avoid using damaged or excessively worn reducers or discs.
