BEVELLING BEVELLING CUTTERS AND TOOLS atagroup. com

Cutters can be used for bevelling and chamfering edges as well as rounding the edges with a perfect precise radius Cutters are applicable on Steel and Stainless-Steel applications Consistent results for angle or rounding applications, higher level of workpiece uniformity achievable Accurate and effortless process to create welding edges or machined chamfers Reduced vibration and noise levels compared to grinding or tools with inserts Reduction in air pollution and sparking around the working environment caused by ‘fine dust particles’ Reduced downtime when changing consumables compared to tools with inserts Minimal heat transmission into the workpiece Prevents discoloration and creates a clean surface that does not require additional treatment Welding metal is a skilled, physically demanding and time-consuming job. The quality of the weld preparation is key to ensure a strong weld. Similarly, the rounding of edges on metal has never been so important to ensure compliance with safety regulations. You can now chamfer and round edges more accurately and more efficiently with the Karnasch Bevelling Cutters and Tools. Make an accurate, precise smooth angle or radius in just one simple effortless step. Ideally suited for welding preparation, chamfering and radii profiling FEATURES & BENEFITS • Welding • Offshore • Pipeline • Shipbuilding • Marine • Steel construction • Bridge building • Vessel production • Tank building INDUSTRIES • Weld preparation • Deburring • Countersink connections • B evel heads are available with angles of 30° | 37.5° | 45° APPLICATIONS • Paint / coating adhesion • Smooth finish • Cable feed • R adius cutters are available with a radius (R=mm) of R2, R3, R4, R6, R8 cutters BEVELLING RADIUS 2

Flange Head Adjustable flange can cater for various cut depths Bevelling Air Tools Bevel faster with the range of Karnasch bevelling air tools. The tools have an excellent power to weight ratio, offering consistently high quality cutting with minimal physical effort. The bevel can be adjusted to various depths easily and can be replaced very quickly. For lighter bevelling and radius work, up to a depth of 6mm, Karnasch offers the P25-BT (130100) and SM16-BT (130110). Specially designed for quick rounding of small sheets, pipes and holes, with depth adjustments of 0.125mm increments, the tools are precise and easy to use. Designed for heavy-duty bevelling up to a depth of 12mm or radius work up to 8mm, with depth adjustments of 0.25mm increments, the RA14-BT (130120) offers a powerful 1.5HP motor ensuring that even the most physically demanding and time-consuming work is completed more efficiently. 130120 130110 RA14-BT SM16-BT 4

When bevelling, approach the workpiece at a 45° angle. Ensure that the flange head is flat on the workpiece. Do not use excessive force. To ensure a precise, uniform and consistent cut, the flange head must be flat on the workpiece. 90° For internal grinding use the tool in a clockwise motion. For external grinding use the tool in an anti-clockwise motion. 45° 10
