MFR Mini Boring Bar For Steel/Stainless/Titanium Micro Fine Boring Internal Grooving 1mm-8mm Range
Introduction:
Our MFR Mini Boring Bar is a precision solid carbide tool designed for micro fine boring, internal grooving, and small-diameter machining in steel, stainless steel, and titanium. Engineered with ultra-fine grain carbide and optimized geometry, this industrial-grade boring bar delivers exceptional accuracy (±0.005mm), superior surface finishes (Ra < 0.4μm), and extended tool life—ideal for CNC lathes, Swiss-type machines, and machining centers.
Features:
✔ Solid Carbide Construction – High rigidity for vibration-free machining.
✔ Micro-Diameter Range (1mm-8mm) – Precision boring in tight spaces.
✔ Optimized Flute Design – Efficient chip evacuation in deep holes.
✔ Threaded/Shank Options – Compatible with MFR, C5, C6, and other standard tool holders.
✔ Through-Coolant Capability – Optional internal coolant channels for heat management.
✔ High-Precision Ground Edges – Ensures consistent bore quality and tight tolerances.
✔ Multi-Material Ready – Works on steel (HRC 45+), stainless (304/316), titanium (Grade 5), and superalloys.
✅ Ultra-Fine Boring Accuracy (±0.005mm) – Perfect for medical, aerospace, and automotive components.
✅ Reduced Vibration – Balanced design prevents chatter in deep-hole machining.
✅ Longer Tool Life – 3X durability vs. HSS boring bars.
✅ Internal Grooving & Undercutting – Versatile for complex internal features.
✅ High-Speed Compatible – Stable performance at 20,000+ RPM.
Medical Implants – Precision boring of bone screws, dental fixtures.
Aerospace Components – Fuel nozzles, hydraulic valves, turbine blades.
Automotive Injectors – Micro-hole boring for fuel injection systems.
Watchmaking & Electronics – Ultra-precise bushing and bearing bores.
Mold & Die – Ejector pin holes, micro-cavities.
