Adjustable Hand Reamer (10–26 mm) — precise, durable reaming for metalwork Why you need this reamer Achieve accurate hole sizes without changing tools: the adjustable 10–26 mm range lets you set the exact diameter you need for multiple jobs. Improve fit and finish: high-speed steel cutting edges reduce surface roughness and deliver a cleaner bore for semi-finishing operations. Simplify work and retain control: manual operation gives full tactile control over cutting pressure and feed, so you can fine-tune results without complex machinery. Key benefits and what makes it stand out Precision adjustment: a single tool covers a wide diameter range (10–26 mm), reducing tool swaps and saving time. Durable cutting material: made from high-speed steel (HSS) for reliable wear resistance and consistent cutting performance. Better surface quality: designed to smooth and refine bores, making it ideal for semi-finish tasks where dimensional accuracy and surface condition matter. Versatile compatibility: works on steel, alloy steel, cast iron and aluminum, so it handles most common metalworking needs. Easy to use: manual design provides simple, intuitive control suitable for both professionals and DIY users. Typical applications Auto repair: finish or slightly enlarge engine or transmission bores and mating holes to restore fit and reduce vibration. Metal fabrication and maintenance: refine drilled holes in steel frames, brackets, and fittings to ensure proper alignment and fastener seating. DIY and workshop projects: adjust and finish holes in aluminum panels, cast parts and alloy components without needing a machine reamer. Practical features at a glance Adjustable diameter: 10–26 mm Material: high-speed steel (HSS) Suitable for: steel, alloy steel, cast iron, aluminum Operation: manual hand reaming for controlled, semi-finishing work What you can expect Consistent, controllable hole sizing across a range of diameters Improved surface finish compared with rough-drilled holes A single, durable tool that covers multiple jobs and materials Use this adjustable hand reamer when you need precise, clean bores without the expense or setup of powered machines.
