Description
Overview:
The Brushcutter/Trimmer Reduction Ring 1 inch to 20mm is a precision-machined metal adapter used to match blade bores to machine arbors on brushcutters and trimmers. It reduces a 1 inch blade centre hole to 20 mm (1 inch = 25.4 mm), allowing a 25.4 mm bore blade to be safely fitted to a 20 mm spindle. The ring sits inside the blade bore to centralise the blade, improve clamping, and maintain correct alignment. Suitable for petrol or battery brushcutters and clearing saws using metal cutting blades, grass blades, or brush knives. Designed for dependable day-to-day use in garden, estate, and site maintenance. Manufacturer Part Number: 350 184.
