Grinding and honing brush 28x200 mm, grain 180 - Bore processing

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

* Application:

* Automotive:

* Engine cylinders, connecting rods, bores on shafts and cranks, pneumatic and hydraulic cylinders, valve guides, compressed air equipment, wheel brake cylinders, brake control cylinders, tubes 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 abrasive beads adapt to the surface. The brush can thus be used for deburring and finishing surfaces (even in non-round bores). * ideal tool for creating a uniformly finely ground surface with high contact area, the so-called plateau finish, creating a cross-hatch that is an excellent carrier for potential oil film adhesion, resulting in a surface free of cold-formed and deformed material * easy handling on both hand drilling machines and 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, for hydraulic brake cylinders use brake fluid instead * recommended speed: 350 - 700 rpm * Rotation: 60 to 120 strokes/min * Accelerated rotation produces cross-hatch of 45° to 60° * Clean bore with hot water or cleaning agent using nylon tube brushes * Lightly oil bore after cleaning * Honing time: approximately 20 to 40 seconds
