HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (H15 (38.0-46.0 mm))

• Premium HSS M2 Grade Blades: Manufactured from industrial-grade High-Speed Steel (HSS) M2 grade, these blades are celebrated for their extreme toughness and superior heat resistance. This high-performance material ensures the tool maintains its razor-sharp edge and dimensional accuracy even when working with heavy industrial materials.
• 38.0 mm – 46.0 mm Wide Expansion Range (Size H15): This single tool offers a substantial 8 mm adjustment span. It allows you to achieve any custom diameter between 38 mm and 46 mm, effectively replacing the need for an extensive collection of individual fixed-size reamers.
• Precision Dual-Nut Adjustment System: Equipped with heavy-duty 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 secure, custom fit.
• Industrial Heavy-Duty Build: With a length of approximately 16 inches and weighing 4.36 lbs (approx. 2 kg), the H15 model is specifically engineered for large bores and heavy machinery maintenance. Its substantial weight provides the necessary stability and leverage for manual reaming of larger diameters.
• Professional Grade Finishing & Repair: An ideal solution for automotive engine overhauls, ship maintenance, and heavy plant engineering. It is the essential choice for resizing oversized bushings and providing high-accuracy finishes to critical industrial bores.
• Smooth & Chatter-Free Performance: The precision-ground finish and multi-blade configuration work together to minimize vibration (chatter). This ensures a clean, mirror-like smooth internal finish, even in large-diameter applications.
• Versatile Selection: As a key part of the premium ASSORTS range (HV to H19), the H15 model is designed for major projects where durability, accuracy, and precise alignment are the highest priorities.
