Key benefits Accurate taper control: 1:10 conical degree provides predictable, repeatable taper geometry for precise fits and smooth assembly. Durable cutting edge: manual pin and blade are made from HSS alloy steel 9XC for wear resistance and consistent cutting performance. Wide size range: available in 8, 10, 12, 14, 16, 18, and 20 mm to match common tapered-bore requirements without compromise. Built for repeated use: body made of 96# silicon material for reliable durability in regular machining tasks. What this tool does for you Produces clean, accurately tapered bores for press fits, bearing seats, and tapered components. Reduces rework by delivering a consistent taper and finish when used with appropriate machines. Offers flexibility across multiple projects thanks to the range of sizes and compatibility with standard taper shank setups. Features and specifications Taper: 1:10 conical degree. Cutting material: HSS alloy steel 9XC (manual pin and blade). Body material: 96# silicon. Type: tapered chucking spiral reamer. Available sizes: 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm. Intended for use with taper shank machine reamers, CNC tools, and similar machining equipment. Practical use scenarios Precision repair: Refinish worn tapered bores in machinery to restore proper bearing and shaft alignment. Production finishing: Use on a CNC or taper-shank machine to put the final taper and surface finish on components before assembly. Toolroom and maintenance: Create or fine-tune tapered holes in fixtures, housings, or custom parts during prototyping and maintenance work. Compatibility and tips Designed to work with taper shank machines and standard CNC setups—confirm machine tooling and holding method match the reamer shank. Choose the reamer size that matches the intended final bore diameter; use steady feed and correct RPM for best finish. Inspect cutting edges and reamer condition regularly; replace when wear affects accuracy or finish. Materials, sizes, and performance are consistent with the original specifications: 1:10 taper, HSS 9XC blade/manual pin, 96# silicon body, and available in 8–20 mm sizes.
