Special Grinding and Honing Brush 30x200 mm, Grit 180

* Brush Ø: 9.0-64.0 [mm] * Overall length: 200 mm

* Application:

* Automotive:

* Engine cylinders, connecting rods, bores in shafts and cranks, pneumatic and hydraulic cylinders, valve guides, compressed air equipment, wheel brake cylinders, brake control cylinders, pipes and hoses and many other applications in automotive repair * Aerospace * Hydraulics * Heat exchangers etc.

* Features:

* robust, self-centering honing tool for gentle grinding process * Due to the flexible construction of the brush, the grinding media spheres adapt to the surface. The brush can thus be used for edge breaking and finishing of surfaces (also in non-round bores). * ideal tool for producing a uniformly fine ground surface with high bearing area, the so-called plateau finish, creating a cross-hatch pattern that is an excellent carrier for possible oil film adhesion, resulting in a surface free of cold-deformed and deformed material * easy handling on both hand drill machines and in honing machines and automats * How to work with the grinding and honing brush? * always wear safety glasses and gloves * Select brush diameter according to bore diameter if not available, select a larger diameter (e.g.: For bore Ø 11.5 = use brush for bore Ø 12)

* use oil with viscosity 10 to 30 or honing oil, on hydraulic brake cylinders use brake fluid instead * recommended speed: 350 - 700 rpm * Rotation: 60 to 120 strokes/min * Accelerated rotation produces a cross-hatch of 45° to 60° * Cleaning of the bore with hot water or detergent using nylon pipe brushes * lightly oil bore after cleaning * Honing time: approximately 20 to 40 seconds
