Product Description Product Detailed DescriptionThe SCPR3/SCPR6 small boring tool is engineered for high-precision machining of small-diameter holes (typically 3-12mm), making it an essential tool for industries requiring intricate hole finishing, such as aerospace, automotive parts, and precision electronics manufacturing. Designed to deliver exceptional accuracy and stability in confined spaces, this compact boring tool combines robust construction with optimized geometry to meet the demands of miniature hole machining.Key Features:High-Grade Carbide Construction: The cutting edge of the SCPR3/SCPR6 is crafted from ultra-fine grain carbide, ensuring superior hardness (≥90 HRA) and wear resistance. This allows for consistent performance even when machining hardened steels (up to 45 HRC) and alloy materials, extending tool life by 30% compared to standard small boring tools.Precision-Ground Geometry: Featuring a sharp, honed cutting edge and optimized rake angle, the tool minimizes cutting forces to reduce vibration-critical for maintaining tight tolerances (±0.002mm). The design also promotes smooth chip evacuation, preventing chip clogging in small holes and ensuring a burr-free surface finish (Ra ≤ 0.8μm).Compact & Rigid Design: With a slim shank diameter (3-6mm, corresponding to SCPR3/SCPR6 models), the tool easily accesses deep, narrow holes while maintaining rigidity. The integrated coolant channel (optional) enhances heat dissipation, protecting both the tool and workpiece during high-speed machining (up to 1500 RPM).Versatile Compatibility: Compatible with standard CNC lathes, milling machines, and miniature machining centers, the SCPR3/SCPR6 works seamlessly with common tool holders. It supports both through-hole and blind-hole machining, adapting to diverse workpiece geometries.Ideal Applications:Material Compatibility: Perfect for machining carbon steel, alloy steel, cast iron, and non-ferrous metals (aluminum, brass) in small-diameter holes.Industry Uses:Aerospace: Fuel injector nozzles, sensor mounting holes.Automotive: Precision valve guides, small hydraulic components.Electronics: Connector pin holes, micro-motor housing bores.
