Product Details

✓[IN THE BOX]: 1 each Pro-Graad TwistFlex Size: 3 1/2" 3.5" (64mm) Bore Diameter, Grit: 400 Silicon Carbide, Working Length of Brush 3 1/2", Shaft Diameter 0.315", Overall Length 13.5". NOTE: ORDER BY THE BORE SIZE – THIS SIZE HONE IS for USE ON BORE DIAMETERS 3.3" - 3.5".

✓[PRECISE DESIGN]: The Pro-Graad TwistFlex 3 1/2 Cylinder Honing & Deburring Tool is manufactured oversized - ORDER BY THE BORE SIZE. Brush will be approximately ten percent oversized, but will easily conform and fit into the bore size diameter due to the flexibility of the honing tool stems.

✓[EVEN PRESSURE & FINISHING]: Pro-Graad TwistFlex Cylinder Honing & Deburring Tool brushes have round abrasive spheres fastened to ends of flexible stems, which produces pressure and finishing evenly and consistently. Excels on mild steel, stainless steel, cast iron and other softer ferrous materials.

✓[VERSATILE APPLICATION]: The Pro-Graad TwistFlex Cylinder Honing & Deburring Tool can be run with hand tools, drill press, or CNC equipment. Apply a lubricant liberally such as a honing tool lubricant, 10-30 weight motor oil, or transmission fluid prior to using honing tool brush. Max RPM is 600, however optimum range is 300 - 500 RPM. Tip: If producing cross-hatching pattern, less is best - maximum of two passes should be done with brush within 20-45 seconds of total run time, averaging between 10-55 strokes.

✓[AUTOMATIC ALIGNMENT]: The 3.5 inch TwistFlex Cylinder Honing & Deburring Tool is self-centering, self-aligning and will conform to the bore diameter to provide consistent surface finishing, as well as deburring any cross-drilled holes. The brush is self-compensating to produce a consistent finish throughout the life of the tool.
