#11 HIGH Speed Steel Straight Flute Taper PIN Reamer

Description

Product Overview

The High Speed Steel Straight Flute Taper Pin Reamer is engineered for professionals who demand exacting tolerances and reliable performance in high‑stress environments. Crafted from premium high‑speed steel (HSS), the tool offers superior hardness, heat resistance, and wear resistance, ensuring a long service life even under continuous use. Its straight‑flute geometry provides smooth chip evacuation, reducing heat buildup and extending cutting efficiency. With an overall length of 11-1/4 inches, the reamer fits a wide range of machine setups while maintaining a compact profile that eases handling and storage. The product ships in a compact 4 × 4 × 3‑inch package weighing approximately 2 pounds, making it convenient for both workshop inventory and on‑site applications. Designed to meet the exacting standards of aerospace and automotive manufacturing, this taper pin reamer delivers consistent hole diameters and surface finishes, minimizing the need for secondary finishing operations. Its robust construction, combined with a precision‑ground tip, ensures that each pass produces clean, burr‑free holes, enhancing overall assembly quality and reducing rework costs.

Usage

This reamer excels in a variety of industrial settings, including aerospace component machining, automotive engine block preparation, and precision equipment manufacturing. It is ideal for creating tapered holes that accommodate pins, dowels, and alignment fixtures, providing a secure fit that resists loosening under vibration. The tool is compatible with CNC milling machines, manual drill presses, and handheld power tools, offering flexibility for both automated production lines and custom, low‑volume projects. Operators appreciate the straight‑flute design for its ability to clear chips quickly, which is especially beneficial when working with difficult‑to‑cut alloys such as titanium or high‑strength steels. The reamer’s high‑speed steel composition allows it to maintain cutting edge integrity at elevated spindle speeds, reducing cycle times and improving throughput. Whether you are reaming holes for hydraulic fittings, gear shafts, or structural fasteners, the consistent taper geometry ensures a precise fit that meets engineering specifications without the need for additional machining steps.
