Deburring Tool For Uneven Surfaces

COFA, a deburring tool, was made for dirough-hole NC deburring applications. The device provides even deburring on uneven surfaces, front and back deburring in a single pass without stopping or reversing the spindle, consistent edge break every time, straight hole and ID deburring of 1/4" or larger, and carbide TiN-coated blades that are said to outlast HSS blades. The tool has no adjusting screws or presetting requirements. Tle tool"s carbide cutting blade follows the contours of the hole"s edge, removing all burrs while creating a radius-tapered edge rather than a 45 degree angle corner break. Using the company"s cutting geometry, the blade pivots around the hole"s edge and passes through without damaging the bore"s surface. The tool comes in three sizes of cutting blades. Four spring types are available determined by workpiece material: soft (for aluminium, brass, and so on), normal (cast iron, steel, and similar materials), hard (such as hardened steel), and super hard (nickel alloys, and so on). All tool bodies within each series use the same spare parts and blades. Recommended hole-to-cross-hole ratio is less than 2 to 1. Recommended surface angle is less than 15 degrees. The tool also comes with a back-cutting blade only.
