BC9M18 Flexible Cylinder Hone 180 Grit","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe BRUSH RESEARCH MFG. BC9M18 is a flexible cylinder hone designed for precision bore finishing in tight cylindrical passages. It uses silicon carbide abrasive balls bonded to flexible filaments, allowing the tool to self-center and conform to the bore as it works. The extra fine 180-grit rating makes it suited for finish honing, light material removal, and surface conditioning rather than aggressive stock removal. With an overall length of 8 inches and a maximum bore diameter of 0.35 inches, it is built for small-bore applications. HVAC service techs, machinists, and engine rebuilders use this tool with a standard drill or drill press.\u003c\/p\u003e\u003cp\u003eThis hone is sized for small-diameter bores up to 0.35 inches, making it practical for valve bodies, hydraulic cylinders, small engine cylinders, and similar tight passages. The 2-inch abrasive length provides consistent contact across a short working zone. Compatible material applications include mild steel, stainless steel, and cast iron, covering a wide range of common service scenarios in mechanical and industrial settings. The 0.14-inch shank diameter fits standard drill chucks without an adapter in most cases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive rated at 180 grit for extra fine surface finishing\u003c\/li\u003e\n\u003cli\u003eMaximum bore diameter of 0.35 inches suits small-bore valve and cylinder work\u003c\/li\u003e\n\u003cli\u003eFlexible filament design self-centers in the bore for even abrasive contact\u003c\/li\u003e\n\u003cli\u003e2-inch abrasive length provides a focused working zone in short bores\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 1200 RPM for use with standard drills\u003c\/li\u003e\n\u003cli\u003eCompatible with mild steel, stainless steel, and cast iron workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for bore finishing in mild steel, stainless steel, and cast iron components with bore diameters up to 0.35 inches.
