Product: Adjustable Manual Hand Reamer (10 mm – 26 mm) Key benefits Delivers precise hole finishing and consistent cylindrical results to correct drill oversize, reduce surface roughness, and meet tight tolerances (H8 fit). Saves time by producing accurate, straight holes without the need for remachining or additional tooling. Durable, longlasting cutting performance thanks to six speed steel (HSS) cutting edges designed for smooth operation across common metals. What it is and how it works Manual adjustable hand reamer with a working diameter range covering 10 mm to 26 mm. Uses six balanced HSS cutting edges for stable cutting action and dimensional stability during reaming. Cylindrical reaming profile engineered to avoid material deformation and maintain straightness and roundness. Sizes and compatibility Available in 10 selectable diameter ranges (for example, 10–10.75 mm up to 23–26 mm); each model is clearly labeled by its cutting range for quick identification. Produces holes to an H8 tolerance fit, suitable for applications that require reliable hole size control. Compatible with generalpurpose machine chucks and suitable for use in manual reaming operations in machining centers and milling setups. Materials and performance Cutting edges made of speed steel (HSS) for wear resistance and long life. Designed for use on A3 steel, alloy steel, cast iron, and aluminum. Provides smooth finishes and improved hole dimensions after drilling, reducing the need for secondary finishing. Typical applications / use scenarios Machine : Final sizing and finishing of bolt holes and bearing seats on milled parts to H8 tolerances before assembly. Maintenance and : Truing and resizing holes in gear housings, brackets, or welded assemblies where rebuilt parts must accept fasteners or bearings. Light production: Hand or machineassisted reaming of aluminum and steel components in smallbatch fabrication or prototyping where flexibility across a range of diameters is needed. Practical notes Select the model covering the desired diameter range; adjust carefully and feed with steady, even pressure to preserve blade life and achieve the H8 fit. Suitable for use by hand or in generalpurpose machine chucks; avoid excessive radial force to maintain roundness and avoid blade damage.
