Description
Overview:
The Draper Cylinder Hone 25mm-57mm is a spring-loaded three-leg honing tool for restoring and deglazing small-bore cylinders found in motorcycles, scooters and other compact petrol engines. Built with a flexible steel drive shaft and three abrasive 220-grit stones, it aligns easily to the bore and follows minor imperfections for an even finish. It fits standard handheld drills, whether mains electric or air-powered, and is rated up to 2400 r/min. With an overall length of 210mm, it provides good reach and control when working in confined engine bays. Compatible bore range is 25-57mm (approximately 1-2.24 inches), making it suitable for many small engines used in garden and construction equipment. Manufacturer Part Number (MPN): 56244.
Key Features:
- Working range suits small cylinders: 1-2.24 in (25.4-56.9 mm) within the stated 25-57 mm tool capacity
- Flexible drive shaft for easy alignment and smooth, concentric operation
- Adjustable honing pressure for controlled stock removal and surface finish
- Supplied with 220-grit stones; replacements available to extend tool life
- Suitable for electric and air drills; operates up to 2400 r/min
- Overall length 210 mm for improved access and handling
- Steel arms and robust construction designed for repeat workshop use
- Even contact across the bore helps deglaze and prepare for new piston rings
- Simple setup; stones compress to enter the bore and expand under spring tension
- Practical for maintenance routines where accuracy and repeatability matter
Typical Applications:
Deglazing and finishing small engine cylinder bores before fitting new rings, removing light glaze and minor high spots, and improving crosshatch on motorcycle and moped engines. Also useful on compact garden and site equipment such as lawnmowers, brushcutters, generators, water pumps and small compressors, provided the bore size falls within 25-57 mm.
