About this item

  • RESTORES OPTIMAL ENGINE PERFORMANCE: Designed for professional engine rebuilding, this cylinder hone tool effectively removes glaze and carbon deposits from cylinder walls. It creates a precise 45-degree crosshatch surface finish, ensuring rapid and proper piston ring seating to restore optimal compression and prevent blow-by.
  • PREMIUM SILICON CARBIDE ABRASIVES: Constructed with industrial-grade 240 grit silicon carbide abrasive globules suspended on flexible nylon filaments. Unlike cheap metal stones that can gouge cylinders, our ball hone provides a soft cutting action. It maintains accurate cylinder geometry without altering the bore size, making it safe for cast iron and aluminum blocks.
  • EXACT SIZING FOR 4.125" (105MM) BORES: Size matters for a perfect hone. This specific engine cylinder brush is engineered for bore sizes around 4.125 inches (105mm). The tool itself is manufactured slightly oversized to provide the correct wall tension.
  • EASY TO USE & MULTI-PURPOSE: Designed for use with any standard hand drill or drill press (recommended 350-700 RPM). Beyond automotive engine blocks, this bore honing tool is highly effective for smoothing hydraulic cylinders, brake master cylinders, pneumatic tools, and marine engine tubes.
  • CRITICAL LUBRICATION & CLEANING REQUIRED: To achieve the best surface finish and prolong tool life, always use high-quality honing oil or SAE 30 weight motor oil during operation (never use dry). After honing, thoroughly scrub the cylinder wall with hot soapy water and a stiff nylon brush until a white lint-free cloth comes out perfectly clean.
