MGR series tungsten steel small hole grooving tool 0.3-4mm precision grooving carbide multi-edge boring tool
Material and Process
Using high-quality tungsten steel alloy or cemented carbide material, the hardness can reach HRA92 or above, and the wear resistance and impact resistance are significantly better than ordinary high-speed steel.
Special surface coating treatment (such as nano blue coating) further reduces the friction coefficient and extends the tool life to 3-5 times that of ordinary tools.
Anti-vibration tool bar technology: The built-in shock-absorbing structure can reduce the vibration amplitude by 50%, ensuring that the aperture tolerance is controlled within ±0.005mm.
Modular tool head: supports rapid replacement of 1-10mm diameter range to meet different working conditions.
Precision machinery field
Aerospace: Processing of fuel nozzle micropores (minimum aperture 0.8mm.
Medical equipment: Finishing of titanium alloy artificial joint inner holes (surface roughness Ra≤0.4μm.
Challenges of complex working conditions
Processing of stainless steel 304 material: cutting speed can reach 120m/min, and chip breaking effect is excellent.
45° blind hole expansion: The taper design of the tool body ensures processing stability and avoids tool tip breakage.
Industrial Revolution of Micro-hole Processing
In the field of precision manufacturing, micro-hole processing with a hole diameter less than 10mm has long faced three major pain points: short tool life, low dimensional accuracy, and poor material adaptability. When traditional high-speed steel tools process titanium alloys, the life of a single blade is less than 200 pieces; and the processing yield rate of difficult-to-cut materials such as hardened steel is even lower than 80%. The birth of the MFR series of small hole boring tools has pushed micro-hole processing into a new era of "nano-level precision + thousand-piece life" through the dual breakthroughs of material science and structural mechanics.

The MFR series small hole boring tool is not only a tool, but also a cross-border integration of material science, precision machinery and digital technology. In the process of transition from Industry 4.0 to 5.0, it redefines the possibility of micro-hole processing with "nano-level precision, military-level reliability, and mass production-level cost", and has become a model of domestic substitution in the field of high-end manufacturing.
