HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (H3 (11.0-12.0 mm))

• Premium HSS M2 Grade Blades: This adjustable hand reamer is manufactured with industrial-grade High-Speed Steel (HSS) M2 grade blades, celebrated for their exceptional hardness and wear resistance. This premium material ensures the tool maintains its sharpness over long periods and delivers consistently precise cutting performance.
• 11.0 mm – 12.0 mm Adjustable Range (Size H3): Achieve any custom hole size within the 11 mm to 12 mm span with this single precision tool. This versatility saves you the expense of purchasing an extensive inventory of individual fixed-sized 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. It is the dependable choice for resizing worn bushings and providing a flawless final internal finish to any bore.
• Smooth & Chatter-Free Operation: The precision-ground finish and multi-blade circular geometry significantly minimize vibration (chatter) during use. This results in an exceptionally clean, mirror-like smooth internal finish that meets strict engineering standards.
• Durable & Compact Design: Weighing only 1.1 pounds, this tool is well-balanced and easy to maneuver, making it perfect for high-precision field work. Its robust construction is engineered to withstand demanding heavy-duty metalworking tasks.
• Versatile Selection: As part of the premium ASSORTS range (spanning HV to H19), the H3 model is your ultimate solution for finishing "odd-sized" holes and projects requiring exact tolerances where standard drill bits fall short.
