Precision HSS M2 Pilot H12 Expandable Reamers DIY Finishing Hand Tool

• Precision Pilot Guide for Perfect Alignment: The H12 reamer is equipped with an integrated pilot guide that self-centers within the hole before cutting begins. This feature ensures absolute straight-line alignment in long bushings and deep bores—an essential requirement for critical kingpin and spindle repairs.
• Premium HSS M2 Grade (6-Blade Design): This tool features six High-Speed Steel (HSS) M2 grade blades, renowned for their superior hardness and heat resistance. These blades provide a clean, chatter-free, and highly precise finish, even when working with tougher industrial metals.
• 27.0 mm – 30.0 mm Versatile Range: The H12 model allows you to achieve any custom diameter between 27 mm and 30 mm. This wide adjustment flexibility eliminates the need to invest in a large inventory of expensive fixed-size reamers.
• Extended 430 mm Overall Length: With a substantial 430 mm (approx. 17") Overall Length (OAL) and an 85 mm cutting blade length, this reamer reaches deep into bores and recessed areas where standard-length tools fail to perform.
• Effortless Size Adjustment: High-precision restraining nuts at both ends allow you to expand or contract the blades with surgical accuracy. The dual-nut locking system ensures the tool remains stable and the size remains locked during heavy-duty manual operations.
• Industrial Heavy-Duty Build: Weighing 2.94 lbs (approx. 1.33 kg) and forged with a solid tool-steel body, this reamer is engineered for the rigors of professional-grade metalworking and automotive turning operations.
• Professional Grade Finish: Featuring a precision-ground, rust-resistant finish, this tool is built for maximum longevity in demanding workshop environments. It is the ultimate solution for resizing worn bushings and achieving a high-tolerance final internal finish.
