## Features

- 【Specifications】 - KEENTECH Annular Cutter features a premium carbide cutting edge for outstanding durability, making it ideal for drilling harder materials like stainless steel. It offers a 7/16" cutting diameter and a 1-3/8" cutting depth, and comes with a free pilot pin. The 3/4" weldon shank design is compatible with various magnetic drills, including but not limited to Alfra, Evolution, Dewalt, Vevor, Zelcan and Hougen.
- 【Higher Speed Cutting】- KEENTECH TCT Annular Cutters – engineered to cut faster, last longer, and outperform conventional HSS tools. Featuring an ultra-hard carbide-tipped head and a innovative triple-edge design, the workload is evenly distributed for smoother, more precise cuts – all at 3–5 times the speed of standard HSS cutters. Whether you're working with carbon steel, stainless steel, cast iron, or tough alloys, experience unmatched efficiency and a flawless finish every time.
- 【Better Heat Resistance】- Don't let the heat slow you down! KEENTECH mag drill bits are tipped with premium carbide, engineered to withstand intense temperatures without losing their edge. That means exceptional hardness for faster feeds, cleaner cuts, and maximum productivity. Best of all, you'll slash costs by dramatically reducing tool wear and failure. Get the speed and savings you deserve.
- 【Clean & Crisp Cutting】- For flawless results in high-precision machining, choose KEENTECH TCT Drill Bits. The ultra-sharp cutting edges require less force, ensuring an exceptionally smooth process with reduced friction. This not only delivers a superior surface finish but also minimizes heat buildup, effectively protecting your materials from thermal deformation and burnishing.
- 【Usage Instructions】- To ensure stable cutting and maximize the lifespan of your tool, begin by aligning the two flats of the Weldon shank with the set screws during installation. For optimal performance, always use the recommended cutting fluid, which enables over 1000 cuts, rather than water which may limit you to just 3-5. Finally, by employing the correct RPM and feed rate, you can effectively double your operational efficiency.
