Oregon Tool 28840 Replacement Grinding Stones 5/32 in 3 Pack

Product Description

The OREGON TOOL 28840 is a set of three replacement grinding stones designed for use with compatible electric chainsaw sharpeners. Each stone measures 5/32 inches in diameter and is built for heavy-duty, extended-service use. These stones are the consumable cutting media in bench-mounted electric sharpeners, doing the work of re-profiling dull chainsaw chain teeth to restore proper cutting geometry. Licensed chainsaw technicians, equipment dealers, and professional tree care crews install these as routine maintenance items. The pack contains three stones, sold as a single unit.

These grinding stones are intended for use with electric chainsaw sharpening equipment in shop and field maintenance settings. They are suited for professional chain servicing operations where consistent, repeatable sharpening results are required. Typical users include logging crews, arborists, rental yards, and landscape contractors who sharpen chain on a regular basis rather than replacing it. The 3-count pack supports ongoing maintenance schedules without frequent reorder.

Key Features

• 5/32 inch diameter grinding stones for precise chain tooth engagement

Installation Notes

Replacement grinding stones are typically swapped by a qualified equipment technician or experienced chainsaw operator. Disconnect and power down the electric sharpener completely before removing a worn stone or installing a new one. Follow the sharpener manufacturer's instructions for proper stone seating and guard positioning. Do not operate the sharpener without all guards in place.
