HSS M2 Grade Precision Expandable Reamers DIY Finishing Hand Tool (H16 (46.0-56.0 mm))

• Premium HSS M2 Grade Blades: This adjustable hand reamer is manufactured with industrial-grade High-Speed Steel (HSS) M2 grade blades, renowned for their extreme hardness and superior heat resistance. It maintains a sharp cutting edge and strict dimensional accuracy even when working with heavy industrial-grade materials.
• 46.0 mm – 56.0 mm Extra-Wide Range (Size H16): This single tool provides a massive 10 mm adjustment span. It allows you to achieve any custom diameter between 46 mm and 56 mm, effectively performing the work of several large fixed-size reamers in one versatile tool.
• 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 professional-grade custom fit for large-scale bores.
• Heavy-Duty Industrial Dimensions: Featuring an Overall Length (OAL) of 400 mm (approx. 16") and 140 mm long cutting blades, the H16 model is specifically designed for heavy machinery maintenance. Its substantial size provides the stability and leverage required for large-diameter manual reaming.
• Professional Grade Finishing & Repair: Ideal for heavy automotive engine overhauls, industrial plant maintenance, and large-scale fabrication. It is the essential solution for resizing oversized bushings and providing a high-accuracy finish to critical industrial bores.
• Smooth & Chatter-Free Performance: The precision-ground finish and multi-blade circular geometry work together to minimize vibration (chatter). This ensures a clean, mirror-like smooth finish, even when reaming larger diameters.
• Reliable Workshop Essential: As a key part of the premium ASSORTS range (HV to H19), the H16 model is perfect for major projects where accuracy, durability, and precise alignment are of the utmost importance.
