HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (H-9 (19.75-21.5 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 extreme hardness and heat resistance. This premium material ensures that the tool maintains its sharpness and dimensional accuracy over long-term professional use.
• 19.75 mm – 21.5 mm Adjustable Range (Size H9): This single tool provides a precise adjustment span of 1.75 mm. It allows you to achieve any custom diameter between 19.75 mm and 21.5 mm, effectively eliminating the need for an expensive inventory of multiple 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.
• Industrial Grade Dimensions: Featuring an Overall Length (OAL) of 188 mm and 67 mm long cutting blades, the H9 model is built to provide maximum stability and tactile control. It is perfectly sized for heavy-duty bores and complex automotive repairs.
• Professional Finishing Tool: The preferred choice for machinists involved in metalworking, automotive engine repairs, and precision machining. It is the dependable solution for resizing worn bushings and delivering a high-accuracy finish to internal bores.
• Smooth & Chatter-Free Operation: The precision-ground finish and multi-blade circular geometry significantly minimize vibration (chatter) during operation. This results in an exceptionally clean, mirror-like smooth internal finish that meets strict engineering standards.
• Durable Metal Ground Finish: Built to ASSORTS quality standards, this tool features a rust-resistant, precision-ground finish. This robust construction enhances tool life and ensures consistent, professional performance in demanding industrial environments.
