Kolvoii Carbide-Tipped Annular Cutter, 1/2" Diameter x 1-3/8" Depth, 3/4" Weldon Shank (2 Flat) TCT Mag Drill Bit for Stainless Steel, Cast Iron, Hard Steel, High-Speed Cutting with Pilot Pin
【Superior Carbide-Tipped Performance】Experience unparalleled efficiency with this 1/2" x 1-3/8" Carbide-Tipped Annular Cutter. It slices through stainless steel, iron, and hard steel 3-5 times faster than standard HSS. This TCT annular cutter achieves smooth, burr-free holes with rapid feed and minimal vibration, drastically reducing drilling time
【Universal Fit for All Major Mag Drills】Equipped with a standard 3/4" Weldon shank, this annular drill bit is seamlessly compatible with most magnetic drills including Alfra, BDS, CHAMPION, Dewalt, Euroboor, Hougen, Milwaukee. CAUTION: A separate arbor is needed for mills & large drill presses (arbor not included)
【Advanced Triple-Edge Cutting】Our innovative three-edge design on these TCT annular bits distributes cutting force evenly. This not only boosts speed and accuracy but also reduces heat and friction. The result is smoother operation on hard metals and an extended lifespan for these annular cutters
【Built for Extreme Durability】Forged from premium carbide tips, this robust mag drill bit excels in resisting heat and abrasion. It retains its razor-sharp edge through the toughest jobs, ensuring long-term use, minimized tool replacement, and substantial cost savings for your workshop
【Pro Tips for 1000+ Cuts】Maximize the life of your annular cutter drill bit. First, align the shank's flats for secure mounting. Second, use cutting fluid (enables 1000+ cuts) instead of water (fails after 3-5). Finally, optimize RPM and feed rate to double your drilling efficiency. Attention: This annular cutter is not designed for steel plates harder than 300 HBW, including abrasion-resistant steels like AR400 and AR500
