kwb 551400 Ponta abrasiva para cerâmica, cone redondo, cabeça de 20 mm, encabadouro de 6 mm, 1 unid.

Metalworkers and welders reach for this ceramic grinding pin when they need to deburr or shape steel, cast iron, or welds in tight spots. The round cone profile handles both edge work and surface blending, and the noble corundum abrasive holds its edge longer than standard aluminum oxide.

Key specifications

• Shape: Round cone
• Abrasive material: Noble corundum (ceramic)
• Head diameter: 20 mm
• Head length: 30 mm
• Shank diameter: 6 mm
• Maximum rotational speed: 25,000 RPM
• Grit: K60
• Quantity: 1 piece

Why choose it

Ceramic abrasive cuts cooler and stays sharper than conventional grains, so you spend less time dressing the pin and more time grinding. The 6 mm cylindrical shank fits most die grinders and rotary tools, and the cone shape reaches into corners that flat discs cannot.

Ideal use cases

• Deburring machined edges on steel components
• Cleaning and blending welds on frames and brackets
• Shaping cast iron parts before finishing
• Grinding in confined areas with a die grinder

Good to know

Run the pin at or below the rated 25,000 RPM and let the abrasive do the work—excessive pressure shortens tool life. For best results, use a light touch and keep the pin moving to avoid gouging the workpiece.
