Achieve Precise Finishing at a Competitive Price
Flex-Hone GB41824 is a 4-1/8" (105mm) diameter abrasive cylinder hone produced by Brush Research Manufacturing, imported from USA. It features a self-centering, self-aligning design with 240 grit Silicon Carbide beads, ideal for finishing and deburring steel, cast iron, and softer ferrous materials. The tool creates a cross hatch pattern and a true plateau finish, reducing peak metal and improving oil retention in engine cylinders, hydraulic, pneumatic applications. Its engineered oversize creates optimal pressure, ensuring easy use and wear compensation. Suitable for use in hand drills, CNC machines, and other rotating spindles, it supports rapid ring seating, seal performance, and longer seal life.
Reviewers report excellent results on mild steel and cast iron, achieving a finish of 24-32 Microinch (.6-.8 Micrometer). Its versatility extends to firearm chambers, brake cylinders, and port radiusing, making it a preferred choice for automotive and industrial honing tasks. The tool's self-centering feature reduces setup time and ensures consistent results, even in automated machining processes. Delivered from USA, it arrives in 1-2 weeks with all duties included, ensuring a hassle-free import experience.
