Key features

• •Premium-Quality Material: Crafted from M2 high-speed steel (HSS), this 5PCS Taper Chucking Reamer Set ensures exceptional durability and precise cutting performance, maintaining sharp edges even through heavy-duty applications. The HSS construction resists wear and heat buildup, ideal for prolonged use in demanding projects.
• •Versatile 5-Size Set: This comprehensive set includes five commonly used reamer sizes to align or enlarge existing holes to 3/8", 1/2", 5/8", 3/4", and 1", catering to diverse industrial and DIY needs. Each size is precision-ground to deliver consistent hole diameters with minimal tolerance variation.
• •Wide Application Range: Known as Bridge/Construction reamers for their robust metal-penetrating capability, these bits excel in materials like steel, metal, wood, alloy, aluminum, brass, plastic, iron, nickel, copper, and cast iron. Their taper design allows smooth hole enlargement while reducing burr formation.
• •Efficient and Precise Performance: Engineered for heavy-duty use, these reamers align and expand pre-drilled holes with tear-free accuracy, producing smooth, deburred edges. Perfect for bridge construction, steel erection, automotive applications (truck/trailer steering knuckles, pitman arms), and any project requiring precise hole finishing.
• •Secure Grip Design: The shank features three symmetrical flats for a non-slip hold in portable electric and pneumatic tools, minimizing slippage during high-torque operations. To optimize lifespan and cutting efficiency, apply cutting oil before, during, and after use.
