What it is: Adjustable hand reamer for finishing holes in metal, with a working diameter range from 10 mm to 26 mm. Key benefits (why you need it): One tool covers a wide range of hole sizes (10–26 mm), reducing the number of reamers you need to buy and store. Delivers precise, repeatable hole size and shape with H8 accuracy for reliable fits. Designed for finishing work: refines bore roundness and surface finish after drilling or boring. Performance and construction: Made from high-speed steel (HSS) for toughness and long life in finishing operations. Six flutes provide efficient cutting and stable reaming action. Adjustable design lets you dial in the exact diameter within the 10–26 mm range for versatile use. Materials and compatibility: Suitable for steel, alloyed steel, cast iron and aluminum. Works for both professional machinists and home workshop use where accurate bores are required. How it solves common problems: Corrects oversize or slightly out-of-round holes to restore proper fits for bolts, pins or bearings. Eliminates the need to stock many fixed-size reamers by offering a single adjustable tool. Produces consistent H8 tolerance results to improve assembly quality and reduce rework. Typical applications / use scenarios: 1. Repairing and restoring threaded or worn bolt holes in automotive or industrial assemblies to precise diameter for proper fastener fit. 2. Finishing bores in castings and machined parts to accept dowel pins, bushings or press-fit components with controlled tolerance. 3. Small-shop fabrication and maintenance: enlarging and precisely sizing holes in aluminum brackets, steel plates or alloy parts for accurate alignment. Practical notes: Intended for hand reaming/finishing operations; follow standard reaming technique for best results. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. This adjustable HSS hand reamer combines flexibility (10–26 mm range), durable construction (HSS, six flutes) and precise H8 accuracy to deliver dependable finishing results on steel, alloy steel, cast iron and aluminum.
