HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (H7 (16.75-18.24 mm))

• Premium HSS M2 Grade Blades: Manufactured from industrial-grade High-Speed Steel (HSS) M2 grade, these blades are renowned for their exceptional hardness and heat resistance. This high-performance material ensures the tool maintains a sharp cutting edge and delivers precise results over a long service life.
• 16.75 mm – 18.24 mm Adjustable Range (Size H7): Achieve any custom hole size within the 16.75 mm to 18.24 mm span with this single precision tool. This versatility offers a cost-effective alternative to purchasing a wide array of fixed-size reamers.
• 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 with surgical precision, guaranteeing perfect tolerances and a professional custom fit.
• Professional Finishing Tool: An essential asset for metalworking, automotive repair, and precision machining. This tool is specifically designed for resizing worn bushings and providing a high-accuracy finish to pre-drilled holes where standard sizes fall short.
• Smooth & Chatter-Free Operation: The precision-ground finish and multi-blade circular geometry significantly minimize vibration (chatter) during operation. This ensures an exceptionally clean, mirror-like smooth internal finish that meets strict engineering standards.
• Lightweight & Industrial Build: Weighing just 5.6 ounces (approx. 160 grams), this tool is easy to handle and perfect for high-precision field work. Despite its light weight, its robust construction is built to withstand heavy-duty metalworking tasks.
• Versatile Selection: As part of the premium ASSORTS range (HV to H19), the H7 model is your go-to solution for "odd-sized" holes and high-tolerance projects where accuracy is the highest priority.
