Brush Research Flex-Hone GBD41432 GBD Heavy Duty Flexible Cylinder Hone, 4-1/4" Bore, 320 Grit, Silicon Carbide, for Bore Finishing and Deburring

Brush Research Flex-Hone GBD41432 GBD Heavy Duty Flexible Cylinder Hone, 4-1/4" Bore, 320 Grit, Silicon Carbide, for Bore Finishing and Deburring

• Brush Research GBD41432 is a Flex-Hone GBD heavy duty flexible cylinder hone designed for surface finishing and deburring in bores from 4.001 inches to 4.25 inches. It uses 320 grit silicon carbide abrasive globules with a 6 inch abrasive part and 13.5 inches overall length to help create a consistent bore finish.
• Features:
  • 4.25 inches bore diameter with a 4.001 inches to 4.25 inches bore range helps match nominal 4-1/4 inch applications for proper 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 helps maintain stable contact through longer bores for repeatable finishing results.
  • Self-centering, self-aligning, and self-compensating for wear construction helps maintain uniform bore contact during operation.
  • Recommended 350 to 600 RPM operation with lubrication required supports controlled cutting action and helps reduce abrasive loading.
