FLEX-HONE GB33412 Cylinder Hone Tool, 3-3/4" Bore, 120 Grit

FLEX-HONE GB33412 Cylinder Hone Tool, 3-3/4" Bore, 120 Grit

• The FLEX-HONE GB33412 Cylinder Hone Tool from Brush Research Manufacturing is a standard-duty brush-type hone designed for surface finishing, deburring, and plateau finishing in cylinder bores. Sized for a 3-3/4" bore with a 13-1/2" overall length, this Flex-Hone uses silicon carbide abrasive in 120 grit to help produce a consistent cross-hatch finish. The self-centering and self-aligning design makes it useful for automotive engines, industrial equipment, hydraulic components, marine applications, manufacturing, and general bore finishing work.
• Features
  • 3-3/4" Bore Size – Designed for 3-3/4" cylinder bore finishing and related bore service applications.
  • 120 Grit Silicon Carbide – Provides effective cutting action for surface finishing, deburring, and plateau finishing.
  • Brush-Type Flex-Hone Design – Flexible abrasive globules conform to the bore surface for a consistent finish.
  • Self-Centering and Self-Aligning – Helps maintain consistent contact in the bore without complex rigid setups.
  • Surface Finishing – Helps reduce Ra, Rk, and Rpk values while maintaining oil-retention characteristics.
  • Deburring Capability – Can remove burrs from cross-drilled holes and leave a clean, radiused intersection.
  • Plateau Finish Support – Helps create a cross-hatch plateau finish for improved ring and seal seating.
  • Made in USA – Manufactured in the United States by Brush Research Manufacturing.
