HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (HY (8.7-9.5 MM))

• Premium HSS M2 Grade Blades: This adjustable hand reamer is engineered with high-quality High-Speed Steel (HSS) M2 grade blades. Renowned for superior hardness and exceptional wear resistance, this material ensures the tool maintains its sharpness and precision even when working with tougher metals.
• 8.7 mm – 9.5 mm Adjustable Range (Size HY): Achieve any custom diameter within the 8.7 mm to 9.5 mm span using this single precision tool. This versatility makes it the perfect solution for "odd-sized" holes where standard-sized fixed reamers fall short.
• Precision Dual-Nut 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 at a micro-level, ensuring perfect tolerances and a professional-grade fit for every project.
• Compact & Accurate Design: Featuring an Overall Length (OAL) of 113 mm and a 39.3 mm cutting blade length, the HY model provides excellent stability and tactile control. Its design is optimized for working in small, precise bores where maneuverability is key.
• Professional Grade Finishing Tool: An ideal choice for metalworking, automotive engine maintenance, and precision machining. It is the preferred tool for machinists needing to resize old bushings or perform final bore adjustments with high accuracy.
• Smooth & Chatter-Free Finish: The precision-ground circular geometry is designed to minimize vibration (chatter) during operation. This ensures a clean, smooth, and mirror-like internal finish that meets strict engineering standards.
• Reliable Workshop Quality: Manufactured to ASSORTS quality standards, this tool features a rust-resistant, precision-ground metal finish. This robust construction enhances durability and ensures consistent performance in demanding industrial environments.
