A solid carbide lathe boring tool (micro turning bar) is a high-precision cutting tool designed for small-diameter internal turning, boring, and fine-finishing operations on CNC lathes or Swiss-type machines. These tools are ideal for achieving tight tolerances and superior surface finishes in micro-machining applications.

• Diameter Range: Ø 0.1mm - Ø3mm (sub-millimeter tools available)
• Reach: 4 ×D to 10×D (e.g., a 0.5mm bar can bore 5mm deep)
• Tolerances: ± 0.002mm (for medical/dental implants)
• Coatings: Diamond-like (DLC) or TiAlN for non-ferrous/steels
• Coolant: With or Without Through-tool coolant (critical for chip evacuation)

• Sharp, polished edges - Burr-free finishes (Ra
• Negative rake angles - For stability in hardened steels
• Reduced neck design - Maximizes rigidity in deep holes

• Tool Holding: Hydraulic chucks (e.g., SCHUNK Tendo Nano) for 0.005mm.
• Workpiece Stability: Use micro chucks or vacuum fixtures for
• Vibration Control: Dampened tool holders (e.g., Big Kaiser Micro).

• Medical (Bone Screws, Dental Implants)
• Watchmaking (Gear Pivots,
• Aerospace (Fuel Nozzles, Inconel Micro-Holes)

• Advanced grinding machines: All of our grinding machines are WALTER and SAACKE brands.
• Advanced inspection machines: We have ZOLLER, OMEGA, PG1000, etc. for inspecting each carbide tool.
• Highly skilled design team: Specialized in producing complicated customized carbide tools with designs tailored to workpieces.
• Fast feedback: 24 hours online service.
• Strict quality control: Three-stage inspection process (raw material, semi-finished product, final pre-shipment check).
