Brush Research Flex-Hone GBD40032 GBD Heavy Duty Flexible Cylinder Hone, 4" Bore, 320 Grit, Silicon Carbide, for Cylinder Bore Finishing and Deburring

Brush Research Flex-Hone GBD40032 GBD Heavy Duty Flexible Cylinder Hone, 4" Bore, 320 Grit, Silicon Carbide, for Cylinder Bore Finishing and Deburring

• Brush Research GBD40032 is a Flex-Hone GBD heavy duty flexible cylinder hone designed for surface finishing and deburring cylinder bores from 3.751 to 4.000 inches. Its 320 grit silicon carbide abrasive and 6 inch abrasive part help produce a controlled finish for automotive and general industrial cylinder applications.
• Features:
  • 4 inch bore diameter with a 3.751 to 4.000 inches bore range helps match nominal 4 inch cylinder bores for consistent tool fit.
  • 320 grit silicon carbide abrasive supports extra fine surface finishing and deburring on mild steel, stainless steel, cast iron, and other softer ferrous materials.
  • 6 inch abrasive part and 13.5 inches overall length help maintain stable engagement through longer bores while operating in a rotating spindle.
  • Self-centering, self-aligning, and self-compensating for wear construction helps maintain uniform bore contact for repeatable results.
  • Recommended 350 to 600 RPM operation with lubrication required supports controlled cutting action and helps reduce abrasive loading.
