Kolvoii TCT Annular Cutter 13/16" Diameter x 2" Depth, Mag Drill Bit

Key features

• PRECISE SPECIFICATIONS & READY TO USE: This 13/16" cutting diameter x 2" depth of cut TCT annular cutter is designed for precision deep-hole drilling in thick structural members. To ensure a seamless workflow, each bit comes with a matched pilot pin and L-wrench, providing a complete, "out of the box" professional solution for your metal fabrication needs.
• INDUSTRIAL TCT PERFORMANCE: Engineered with premium Tungsten Carbide Tipped (TCT) teeth, these cutters outperform HSS bits in speed and longevity. Specifically designed for mild steel, stainless steel, and alloys. NOTE: These are NOT intended for ultra-hardened wear plates like AR400 or AR500. Using them on such materials will cause the carbide teeth to dull or chip immediately.
• UNIVERSAL 3/4" WELDON SHANK: Features a standard 3/4-inch Weldon shank with 2 flat surfaces, ensuring a secure, non-slip fit in most major magnetic drill presses like Evolution, Hougen, Milwaukee, and Dewalt. The precision-ground shank provides a stable connection, minimizing vibration and ensuring maximum safety during high-torque operations.
• ADVANCED GEOMETRY & RAPID CHIP REMOVAL: The specialized flute design and heat-resistant carbide tips maximize chip evacuation while minimizing friction. This advanced geometry prevents heat buildup—the #1 cause of bit failure—resulting in cleaner, burr-free, "to-size" holes every time with minimal effort.
• BUILT FOR DEMANDING INDUSTRIAL SCENARIOS: Whether you’re building a custom welding table, repairing bridge I-beams, or working on heavy machinery frames, these cutters deliver unmatched precision. They are optimized for professional use in mild steel, cast iron, and aluminum, making them a staple for any fabrication shop.
