FLEX HONE GBD50024 Heavy Duty Cylinder Hone, 5" Bore, 240 Grit, Silicon Carbide

FLEX HONE GBD50024 Heavy Duty Cylinder Hone, 5" Bore, 240 Grit, Silicon Carbide

• The FLEX HONE GBD50024 is a heavy duty cylinder hone designed for bore sizes between 4.501" and 5", used for plateau finishing in engine blocks, hydraulic cylinders, and industrial bores. It uses 240 grit silicon carbide abrasive globules on flexible nylon filaments and measures 5" in diameter by 17.5" in overall length.
• Features:
  • 240 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.
  • 6" abrasive section with a 0.35" stem, for use in rotating spindles such as drills and drill presses.
  • Heavy duty GBD series construction suited for larger bore applications.
  • Typically achieves a surface finish of 24-32 microinch (0.6-0.8 micrometer) Ra.
  • Recommended operating speed of 350-600 RPM, with a feed rate of 10-2,500 IPM.
