Kolvoii TCT Annular Cutter 11/16" Diameter x 1‑3/8" Depth, Mag Drill Bit
- 【Superior Carbide-Tipped Performance】Experience unparalleled efficiency with this 11/16" 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 seamlessly integrates with most magnetic drills from Dewalt, Hougen, Alfra, and more. The secure clamping design guarantees maximum stability, making it a reliable choice for both professionals and DIYers
- 【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. Products includes a sturdy plastic case with 1 annular cutter, 1 pilot pin, and 1 hex wrench

Select a product to estimate shipping.Why should I choose TCT (Carbide Tipped) over standard HSS bits?
TCT carbide-tipped cutters is a game-changer for industrial drilling. HSS bits burn out fast on stainless steel and hardened I-beams, but our TCT mag drill bits cut these tough materials smoothly, cutting per-hole costs for heavy-duty jobs.
Can I use this TCT cutter for AR400 or AR500 steel plates?
We do not recommend using these cutters for AR400 or AR500 plates. These materials are exceptionally hard and abrasive, which can lead to premature chipping of the carbide teeth if not used with industrial-grade cooling and precision RPM control.
Will this TCT annular cutter fit my specific brand of magnetic drill?
Absolutely. Our annular cutters feature a standard 3/4" Weldon Shank with two precision-ground flats. It is compatible with major brands including Alfra, BDS, Hougen, Evolution, Milwaukee, Dewalt, and Jancy.
What is the best way to prevent the carbide tips from chipping or breaking?
Carbide is hard but can be brittle if mishandled. To maximize tool life: 1.Always use cutting fluid or coolant to reduce heat. 2.Maintain a steady, even feed rate. 3.Fix the magnetic base tightly on clean, flat steel surface to stop vibration.
Can these annular bits drill through a truck frame or hardened alloy steel?
Our TCT cutters are engineered for tough workpieces like hardened truck frames, stainless steel and alloys that ruin ordinary bits. Use low RPM plus steady coolant supply for smooth, clean cuts.
