  • 240 GRIT SILICON CARBIDE CUTS FAST AND LASTS — The 4.125 in. (105 mm) cylinder hone delivers aggressive, consistent cutting action for a clean 45-degree cross-hatch finish on cast iron, steel, and mild steel.
  • SELF-CENTERING FLEXIBLE BALL HONE — Oversized flexible design self-centers and self-aligns inside the bore, holding uniform contact pressure for an even, repeatable finish without altering bore geometry. Chucks into any standard cordless drill.
  • DEGLAZE & RESTORE WORN CYLINDERS — Removes glaze, light rust, and surface imperfections while deburring bores and rounding edges. Preps cylinder walls so new piston rings seat correctly on first start-up.
  • BUILT FOR ENGINE REBUILDING — Restores automotive engine cylinders, block bores, and cylinder walls to like-new condition. A practical choice for DIY garage rebuilds and machine shops that need consistent surface finishing.
  • BRAKE & HYDRAULIC CYLINDER HONE — More than an engine tool: use it on brake calipers, wheel cylinders, and hydraulic or pneumatic blocks. Also at home on motorcycle repair and metal tubing work.
