Product Description Product Detailed DescriptionThe SCPR6-30L-R0.2-D6 small boring tool is a specialized precision cutting tool engineered for high-accuracy boring of miniature holes, designed to meet the strict tolerances of electronics, medical, and aerospace component manufacturing. Each parameter in its model code is optimized for targeted performance: SCPR6 (standard indexable insert type for small boring), 30L (30mm effective cutting length for deep micro-holes), R0.2 (0.2mm nose radius for smooth surface finishes), and D6 (6mm tool shank diameter for stable clamping).Key Application ScenariosElectronics Manufacturing: Perfect for finishing micro-holes (3-8mm diameter) in printed circuit board (PCB) substrates, semiconductor device housings, and smartphone component frames. Its R0.2 nose radius eliminates sharp edges on aluminum or brass parts, ensuring compliance with electronic component safety standards.Medical Device Production: Ideal for boring precision holes in stainless steel or titanium medical instruments (e.g., surgical drill guides, catheter connectors) where hole roundness (≤0.002mm) and surface smoothness (Ra ≤0.8μm) are critical for biocompatibility and fluid flow.Aerospace Miniature Components: Suitable for machining small holes in lightweight alloy parts (e.g., aluminum alloy sensor brackets, titanium valve cores) on CNC lathes. The 30mm effective length enables boring of deep holes (up to 5× diameter depth) without vibration.Precision Mold & Die Making: Used for finishing cooling holes in plastic injection molds (e.g., PEEK mold inserts), where the D6 shank diameter ensures tight clamping in CNC tool holders, reducing runout to ≤0.001mm. Core AdvantagesExceptional Precision: The R0.2mm nose radius delivers consistent surface finishes (Ra ≤0.6μm) on both ferrous and non-ferrous materials, while the tool's overall runout tolerance (≤0.0015mm) guarantees hole concentricity-critical for press-fit component assembly.Stable Deep-Hole Performance: The 30mm effective cutting length (30L) is paired with a rigid carbide shank, minimizing deflection during deep micro-boring (e.g., 6mm diameter × 30mm depth holes in steel). This reduces tool breakage by 40% compared to standard short-length small boring tools.Versatile Compatibility: Designed to fit SCPR6 indexable inserts (compatible with ISO-standard inserts from Kennametal etc.) and standard CNC lathe tool holders (e.g., C6-type collets) via its D6 (6mm) shank. No custom tooling is required for integration into existing setups.Wear Resistance: The tool shank features a TiAlN coating that resists heat and friction, extending tool life by 30% when machining alloy steel (e.g., 4140) at cutting speeds up to 80 m/min. The R0.2 nose radius also reduces edge chipping in brittle materials like cast iron.Cost-Effective Efficiency: Indexable insert design allows quick replacement of worn cutting edges (without replacing the entire tool), cutting tool changeover time by 50%. This makes it ideal for both small-batch prototyping and high-volume production.
