Product Description

Solid Carbide Expansion Reamer with Spiral Flutes Thread Shank Adjustable Diameter for Precision Boring, 1/8" to 3/4"

Our premium solid carbide expansion reamer features an innovative spiral flute design with micro-adjustable diameter capability, engineered for precision hole finishing in demanding industrial applications. The threaded shank ensures secure mounting in CNC machines, lathes, or machining centers, while the expansion mechanism allows precise sizing adjustments within ±0.005mm. Manufactured from ultra-fine grain tungsten carbide, this professional-grade tool delivers exceptional wear resistance and surface finishes up to Ra 0.4μm.

Key Features
  • Solid carbide construction (Grade K30) for maximum rigidity
  • Spiral flute design (35° helix) for superior chip evacuation
  • Precision ground cutting edges with 6-8 flutes
  • Micro-adjustable diameter range: 1/8" to 3/4" (3-19mm)
  • Threaded shank (1/2"-20 UNF standard, other threads available)
  • Adjustable in 0.001" (0.025mm) increments
  • TiAlN or AlCrN coating options
Competitive Advantages
  • Maintains tight tolerances (±0.005mm) in production runs
  • 3X longer tool life than HSS reamers
  • Reduced cutting vibration through balanced spiral design
  • Single tool replaces multiple fixed-size reamers
  • Saves setup time with quick diameter adjustments
  • Excellent results in interrupted cut applications
Typical Applications
  • Precision bore finishing in engine blocks/cylinders
  • Hydraulic component manufacturing
  • Aerospace bearing housings
  • Medical implant fixture holes
  • Die/mold guide pin holes
  • High-volume automotive components
