HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (HV (6.35-7.15 MM))

• Premium HSS M2 Grade Micro-Blades: This HV size reamer is manufactured with high-speed steel (HSS) M2 grade blades. It provides exceptional hardness and heat resistance for small-diameter applications, ensuring the cutting edges remain "razor-sharp" even after extended use.
• 6.35 mm – 7.15 mm Adjustable Range (Size HV): Achieve any custom hole size from 1/4" (6.35 mm) up to 7.15 mm with this single micro-tool. This versatility is ideal for the repair of small precision instruments and delicate mechanical components.
• Precision Dual-Nut Fine Adjustment: Equipped with high-accuracy restraining nuts at both ends. By loosening one nut and tightening the other, you can expand or contract the blades with surgical precision, ensuring micro-level tolerances and a perfect fit.
• Compact Design for Delicate Work: With an Overall Length (OAL) of 90 mm and 36.5 mm cutting blades, the HV model is specifically designed for working in tight spaces. Its compact profile offers superior tactile control for sensitive hand-reaming tasks.
• Professional Finishing & Repair: An essential tool for providing an accurate finish in metalworking, watchmaking, small engine repair, and precision machining. It is the dependable choice for fitting small bushings and pins with high accuracy.
• Smooth & Chatter-Free Operation: The precision-ground finish and multi-blade circular geometry minimize vibration (chatter) during use. This results in a mirror-like smooth internal finish, even in the smallest diameter bores.
• Reliable Workshop Quality: Built to ASSORTS quality standards, this tool features a rust-resistant, precision-ground finish. It is the ultimate solution for finishing "odd-sized" small holes where standard drill bits simply cannot achieve the required precision.
