Product Range

Six Core CNC Cutting Tool Categories

Six representative product groups are shown with unified technical image backgrounds, product photos and three focused specification points. Detailed parameter tables can be added later.

PCD Reamer
01

PCD Reamer

  • Extreme Accuracy and Surface QualityDesigned for micron-level accuracy and ultra-low surface roughness down to Ra 0.1, supporting IT6 and higher precision hole requirements.
  • Long Tool Life and Efficient ProductionPCD hardness is 3-4 times higher than carbide. Tool life can exceed carbide solutions by more than 20 times while supporting high cutting speeds.
  • Preferred for Difficult MaterialsEngineered for high-silicon aluminum alloys, CFRP and other difficult-to-machine materials in automotive and aerospace manufacturing.
PCD Inserts
02

PCD Inserts

  • Ultra-Hard and Wear ResistantHardness up to 8000 HV, 8-12 times higher than carbide. In aluminum machining, tool life can increase by dozens or even hundreds of times.
  • Mirror Finish by TurningA very low friction coefficient reduces built-up edge and enables Ra 0.05-0.1 um mirror finishes, replacing grinding in suitable operations.
  • Grades Matched to ApplicationDiamond grain size is selected by material and finish target: fine grain for finishing and low-silicon aluminum, coarse grain for high-silicon aluminum above 12% Si.
PCD Milling Cutter
03

PCD Milling Cutter

  • High Efficiency for AluminumDesigned for high-speed milling with cutting speeds up to 7000 m/min. In aluminum alloys, productivity can be up to 10 times higher than carbide tools.
  • Stable Precision MachiningMulti-flute cutting edge runout can be controlled within 0.002 mm, delivering Ra 0.6-1.2 um surface quality with sharp cutting edges.
  • Flexible Structures and One-Pass FormingAvailable as flat, ball nose, brazed, indexable or sintered structures. Custom form cutters can combine multiple operations into one pass.
Solid Carbide Drill
04

Solid Carbide Drill

  • High-Precision DrillingDiameter tolerance can reach 0-0.03 mm. Self-centering geometry supports high-quality hole walls and IT7-IT12 tolerance ranges without secondary finishing.
  • Rigid Structure for Productive CuttingThe solid carbide body handles high cutting loads. With TiAlN and other advanced coatings, feed rates can reach 0.70 mm/rev and cutting speed up to 220 m/min.
  • Advanced Cooling for Deep HolesOptimized internal coolant channels improve heat control and chip evacuation, supporting deep-hole machining up to 50xD in suitable conditions.
Solid Carbide End Mill
05

Solid Carbide End Mill

  • High Precision and High RigiditySolid carbide rigidity exceeds HSS tools, with runout controllable within 10 um and even down to 3 um for precision and micro-part machining.
  • High-Performance Cutting GeometryTiAlN, AlTiN and other PVD coatings combine with unequal pitch and variable helix anti-vibration designs to raise metal removal rates.
  • Broad Material Coverage and RegrindingSuitable for steel, stainless steel, aluminum, titanium, heat-resistant alloys and hardened steel up to HRC 65, with regrinding to reduce long-term cost.
Solid Carbide Boring Tool
06

Solid Carbide Boring Tool

  • High Rigidity for Deep BoringSolid carbide bending rigidity is far higher than steel boring bars, reducing chatter and deflection for stable machining at 5xD or even 10xD overhang.
  • Micron Accuracy for Precision HolesMicro boring tools can be produced down to 0.6 mm or even 0.3 mm diameter, with finishing accuracy below 0.005 mm and surface roughness below Ra 0.4 um.
  • Coated, Stable and DurableTiAlN, Al2O3 and other advanced coatings support cutting speeds of 100-400 m/min. Internal coolant improves chip evacuation and process stability.
