the Flex-Hone® Tool BRM's Flex-Hone Tool is protected by... USA Patent Numbers 3384915, 3871139, 5211725, 5353553 US & Foreign Patents Allowed or Pending For Any Type And Size of Cylinder... The Flex-Hone® Process (Super finishing) produces a controlled surface condition unobtainable by any other method. It involves finish, geometry and metallurgical structure. A high percentage plateau free of cut, torn and folded metal (with radiused ports). A resilient, flexible, honing tool with a soft cutting action. The abrasive (points) globules each have independent suspension that assures the Flex-Hone® to be self-centering, self aligning to the bore, and self-compensating for wear. Specifically, it is a low-temperature abrading process that exposes the undisturbed base metal structure to produce a long wearing surface. It is a method of developing a surface on a metal part which is optically smooth and metallurgically free of any fragmented, amorphous or smeared metal from previous operations. It is accomplished at a low pressure where the “stones” float across the surface. The final achieved finish ensures a superior performance in situations dependant on the condition of the surface. The particular type of Flex-Hone® crosshatch is extremely efficient in providing a multiplicity of oil grooves or valleys for oil retention as opposed to the often undirectional or uneven valleys common to the conventional type rigid hone. A crosshatch that usually remains as the cylinder wall has been wear-reduced by the FlexHone®.   WHAT'S NEW with HONE TOOLS... The Diamond Flex-Hone tool is designed for use on any type or size of cylinder from 4mm up to 20mm in diameter. Other sizes are available by special order. Designed for surface finishing and cross hole deburring of harder materials such as carbide, ceramic and space age alloys. This remarkable new Flex-Hone is an efficient solution to your toughest applications. Available in three different grit selections. NOTE: Order by bore size, 4mm- 3/16 are 6" OAL 5mm-20mm" are 8" OAL   If Your Specifications Call For: Developing a surface plateau of over 60% Producing an oil holding cross-hatch pattern Reducing Ra, Rpk and Rvk values Increased bearing area If You Want benefits of: Lowered oil consumption Less blow-by Less friction Improved sealing surface

A hone tool's diameter is determined by the nominal bore size in which the tool is to be operate. A cylinder hone is always produced and used in an oversize condition. The degree of oversize creates pressure and a soft cutting action on cylinder walls. For example a 1" Flex-Hone tool is ordered if a 1" bore (I.D.) is to be finished, the built in oversize provides the proper cut. Remember that all tools are provided in oversized, so do not add inches or mm's to the ID that you are machining. If the bore size is between standard Flex-Hone sizes, the next larger standard Flex-Hone should be selected. Important note: If the Ra (surface finish) of the part being machined needs to change more than 20 to 30 points, you may need to use steps to acheive the proper final Ra. As an example, if you were trying to change a 80 Ra to a 20 Ra, you may need to start with a 120 or 180 grit hone and then finish with a 240 or 320 grit. This stepping concept reduces the chance of damaging the tool due to over heating, when too fine a grit is used for an extended run time to try and remove excessive roughness.   Brake Cylinders, Hydraulics, Valve Guides, etc. 4mm - 3/16" are 6" OAL Balance 8" OAL       Catalog Number MM For Bore Sizes   BC 4mm (.157")     BC 4.5mm (.177")     BC 3/16" (4.75mm)     BC 5mm (.197")     BC 5.5mm (.217")     BC 6.4mm (.250")     BC 7mm (.276")     BC 8mm (.315")     BC 9mm (.354")     BC 9.5mm (.375")     BC 10mm (.394")     BC 11mm (.433")     BC 12mm (.472")     BC 1/2" (12.7 mm)     BC 14mm (.552")     BC 5/8" (16 mm)     BC 18mm (.709")     BC 3/4" (19 mm)     BC 20mm (.787")     BC 7/8" (22 mm)     BC 15/16" (23.8 mm)     BC 1" (25.4 mm)     BC 1 1/8" (29 mm)     BC 1 1/4" (31.8 mm)     BC 1 3/8" (35 mm)     BC 1 1/2" (38 mm)     BC 1 5/8" (41 mm)     BC 1 3/4" (45 mm)     BC 1 7/8" (48 mm)     BC 2" (51 mm)     BC 2 1/8" (54 mm)     BC 2 1/4" (57 mm)     BC 2 3/8" (60 mm)     BC 2 1/2" (64 mm)     BC 2 5/8" (67 mm)     BC 2 3/4" (70 mm)     BC 2 7/8" (73 mm)     BC 3" (76 mm)             Disc Brakes (5" OAL) Catalog Number MM For Bore Sizes DBC 1 1/2" (38 mm)     DBC 1 3/4" (45 mm)     DBC 2 1/8" (54 mm)     DBC 2 1/2" (64 mm)     DBC 2 3/4" (70 mm)     DBC 3 1/8" (79 mm)
