Adjustable hand reamer H1-3/8~13/32 (9.52~10.32 mm)

• Durable Carbon Steel Construction: Manufactured from premium-grade High Carbon Steel (HCS), this H1 reamer is engineered for superior hardness. It delivers sharp, consistent cutting edges, making it the ideal choice for precision field repairs and light machining tasks.
• 9.52 mm – 10.32 mm (3/8" to 13/32") Range: The H1 model provides a specialized adjustment span of approximately 0.8 mm. This tool is specifically designed for finishing "odd-sized" holes where standard drill bits fall short, offering complete flexibility for custom bore sizing.
• Effortless Dual-Nut Adjustment: Features high-precision restraining nuts at both ends. By loosening one nut and tightening the other, the blades slide smoothly along tapered grooves, allowing you to calibrate the cutting diameter at a micro-level to reach your exact required tolerance.
• Professional Epoxy Black Finish: The body is treated with a robust Epoxy Black coating, shielding the tool from moisture and rust in workshop environments. The precision-ground blades and shaft minimize friction during operation, ensuring a mirror-smooth internal finish.
• Specialist Tool for Unbroken Holes: The straight-flute geometry provides exceptional manual control and accuracy in unbroken holes (holes without axial gaps). It is optimized for light-duty manual projects and delicate finishing, allowing for maximum tactile feedback.
• Ultra-Lightweight & Portable: Weighing only 1.76 ounces (approx. 50 grams), this tool offers the perfect balance of structural strength and lightweight handling. Its compact design makes it exceptionally easy to use for on-site engine and machinery repairs.
• Versatile Repair Essential: Specifically engineered for metalworking, small engine maintenance, and engineering workshops. It is a dependable solution for resizing old bushings and providing a precise, clean finish to specialized bores.
