FLEX HONE BC23432 Cylinder Hone, 2.75" Bore, 320 Grit, Silicon Carbide

FLEX HONE BC23432 Cylinder Hone, 2.75" Bore, 320 Grit, Silicon Carbide

• The FLEX HONE BC23432 is a standard duty cylinder hone designed for bore sizes between 2.626" and 2.75" (69.9mm), used for surface finishing, deburring, and edge breaking. It uses 320 grit silicon carbide abrasive globules on flexible nylon filaments and measures 2.75" in diameter by 8" in overall length.
• Features:
  • 320 grit silicon carbide abrasive globules for controlled material removal.
  • Self-centering, self-aligning, self-compensating-for-wear design produces a non-directional, cross-hatched finish.
  • Flexible nylon filaments allow the abrasive globules to float, helping maintain bore alignment.
  • 3" abrasive section with a 0.245" stem, for use in rotating spindles such as drills and drill presses.
  • Typically achieves a surface finish of 18-30 microinch (0.5-0.7 micrometer) Ra.
  • Recommended operating speed of 600-900 RPM, with a feed rate of 10-2,500 IPM.
