FLEX HONE GB41824 Cylinder Hone, 4-1/8" Bore, 240 Grit, Silicon Carbide

FLEX HONE GB41824 Cylinder Hone, 4.125" Bore, 240 Grit, Silicon Carbide

• The FLEX HONE GB41824 is a standard duty cylinder hone designed for bore sizes between 3.751" and 4.125", used for plateau finishing, deburring, and edge blending in engine, hydraulic, and pneumatic cylinder resurfacing. It uses 240 grit silicon carbide abrasive globules on flexible nylon filaments and measures 4.125" in diameter by 13.5" 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.
  • 4" abrasive section with a 0.31" stem, for use in rotating spindles such as drills and drill presses.
  • Typically achieves a surface finish of 24-32 microinch (0.6-0.8 micrometer) Ra.
  • Recommended operating speed of 600-900 RPM, with a feed rate of 10-2,500 IPM.
