Drill America #7 High Speed Steel Helical Flute Taper Pin Reamer

Description

Product Overview

The Drill America #7 High Speed Steel Helical Flute Taper Pin Reamer is engineered for professionals who demand accuracy, durability, and efficiency in every machining operation. Constructed from premium high‑speed steel (HSS), this reamer offers a superior balance of hardness and toughness, ensuring long‑lasting wear resistance even under the most demanding conditions. Its helical flute design actively removes chips from the cutting zone, reducing heat buildup and preventing reamer binding, which translates into smoother cuts and extended tool life. The reamer features a precise taper geometry with a 0.3297‑inch short end and a 0.422‑inch large end, delivering consistent bore dimensions across a range of material thicknesses. The round shank is compatible with standard tool‑holding systems, allowing seamless integration into existing CNC setups or manual tool posts. Package dimensions of 6.5 × 1.1 × 0.5 inches and a lightweight 2.4 oz design make it easy to store and handle, while the DWRRTPH7 model number ensures quick identification and inventory management. Since its introduction on March 30, 2013, this reamer has earned a solid reputation, ranking #66 in the Taper Pin Reamer category on Amazon, reflecting its popularity among machinists seeking reliable performance.

Usage

Designed for a broad spectrum of applications, the Drill America #7 reamer excels in aerospace component fabrication, automotive engine part machining, and general precision engineering tasks. Its high‑speed steel composition makes it suitable for machining hardened steels, stainless steels, and alloyed materials where other tool materials might falter. The helical flute efficiently evacuates chips, making it ideal for deep‑hole reaming where chip congestion can compromise surface finish. Whether mounted on a CNC spindle for high‑volume production or used in a manual lathe for custom prototyping, the reamer delivers consistent bore quality and tight tolerances. The round shank ensures compatibility with a variety of collet sizes, allowing users to select the optimal grip for their specific machine setup. This flexibility makes the reamer a valuable addition to any workshop, from small job shops to large manufacturing facilities.
