The Cogsdill Burraway Deburring Tool is designed as a one-pass solution for simultaneous front and back hole-deburring operations. Operating on a basic spring-tension principle, the tool features a replaceable and adjustable cutting blade that extends upon entry to remove the front burr, automatically retracts as it passes through the workpiece without marring the inside surface of the hole, and re-extends upon emergence from the ID to remove the burr on the back side of the hole on the return stroke. Burraway tools can deburr two or more in-line holes in one pass and are available in both inch and metric programs.
- Double-Acting Operation: Standard tools are assembled with a Double-Acting Positive 4° rake (DAP) blade for deburring both the front and back sides of holes in a single pass.
- Tool Design Variations:
- Type A (Inch) & Type MA (Metric): Two-piece construction consisting of an interchangeable arbor assembly and shank adapter. Covers hole sizes from .093 through .203 in. (2mm to 5mm).
- Type B (Inch) & Type MB (Metric): Single-piece construction. Covers hole sizes from .218 through 1.00 in. (5.5mm through 19mm).
- Type C (Inch) & Type MC (Metric): Single-piece construction. Covers hole sizes from .750 through 2 in. (20mm through 50mm).
- Adjustment Mechanism: Features a tension adjustment mechanism to control the amount of edge break for consistent results. Types A, MA, B, and MB utilize a tension adjustment screw located in the shank end, while Types C and MC utilize a tension adjustment rod.
- Blade Options: Double-acting blades for front and back deburring, as well as dedicated front-cutting or back-cutting only blades. Alternative blade rake angles (Neutral 0°, Negative 4°), carbide-tipped blades, and TiN-coated blades are available.
