Mitigate Jobsite Bind-Up Risks and Maintain Continuous High-Torque Mechanical Boring
The DEWALT DCD446B 20V MAX XR Brushless 1/2-Inch Right Angle Stud and Joist Drill is a compact cordless wood-boring power tool engineered to deliver up to 1,845 max watts out for rigorous framing installations. This heavy-duty right-angle unit drives up to a 4-inch hole saw or a 2-9/16-inch self-feed bit through dense framing timber while spinning at a maximum speed of 1,250 RPM. Outfitted with an advanced electronic Anti-Rotation System that monitors rotational motion and automatically cuts motor power during excessive tool twist, this bare tool maximizes trade productivity for structural electrical and plumbing layouts.
**Battery and charger sold separately.
Best Used For:
- Plumbing Layout Openings: Boring large 4-inch structural clearance holes using hole saws through joists and studs to pass commercial drain lines.
- Electrical Conduit Channels: Drilling serial 2-9/16-inch or auger pass-through routes cleanly across structural framing lumber to run distribution cabling.
- Confined Framing Intersections: Executing high-torque right-angle bit entries inside restrictive stud bays, low overhead clearances, and tight corner layouts.
Key Performance & Safety Features
- Anti-Rotation Protection Technology: Senses sudden torque adjustments and immediately kills tool power, alerting the user via a red structural LED indicator light.
- High-Efficiency Brushless Motor: Delivers advanced motor lifetime and maximizes continuous-run power output under extreme resistance.
- Large Drilling Diameter Threshold: Sustains deep cutting capacity to run up to 4-inch hole saws or 2-9/16-inch self-feed bits safely.
- XR Battery Power Enhancement: Harnesses intelligent power scaling to produce up to 79% more max watts out when stepping up to a DCB2108 pack over basic batteries.
- Tool Connect Smart Integration: Outfitted with an on-board chip pocket configured to accept DCE042 smart tags for effortless cloud tracking on the site manager app.
- Industrial Keyed Chuck Assembly: Utilizes a heavy-duty 1/2-inch keyed chuck interface to guarantee a firm lock and prevent bit slip under load.

PRO-TIP: Although the integrated electronic Anti-Rotation System acts quickly to cut powertrain rotation when a bit binds, always maintain a firm two-handed stance with your secondary support arm extended against the structural framing joists. Providing a reliable structural bracing point allows the high-torque brushless gears to advance with zero lever flex.

outstanding and highly informative book
Format: Paperback
MAoS - Malware Analysis on Steroids: Fighting Malware to the Death - Real-World Threats and Reverse Engineering Tactics by Uriel Kosayev is an outstanding and highly informative book. This is the second book I’ve read from him, after Antivirus Bypass Techniques, and once again I found the content to be extremely practical, well-structured, and insightful. Uriel has a way of explaining complex malware analysis and reverse engineering concepts in a way that is both approachable and deeply technical. The real-world tactics and examples make it not just a book you read once, but a reference you’ll return to often. Without a doubt, another excellent resource—I’m giving it 5 stars.

Great book on Android malware reverse engineering and detection!
Format: Paperback
This book offers a holistic approach for learning how to deal with malware targeting Android platform. I find this book to be equally interesting to read for both people with little experience in the domain of malware analysis as quick-start guide as well as for experienced reverse engineers who would want to translate their knowledge from malware analysis in other platforms to Android. This book is definitely worth the time reading it.
The first half of the book is a great source of information on reverse engineering Android malware. Chapters on categories of Android Malware and examples of the malware in the wild set up the necessary context for the readers and help to better understand why Android malware focuses on certain infection/monetization techniques. It also bring context in the evolution of mitigation and hardening in Android platform.
Chapters on static and dynamic analysis are very practical and engaging to read which I probably enjoyed the most in the book. They teach readers how to do reverse engineering of Android malware -- covers tooling, methodologies, hints to look for in the code or binary artifacts when doing reverse engineering.
The second half of the book is dedicated to using machine learning techniques for detecting malware. It starts with a concise yet self-contained necessary theoretical background. In my point of view the authors hit a very good balance for making material accurate and comprehensive yet easy to read and follow along for people without extensive background in the field (which is not a trivial thing for math texts). As it is probably impossible to fit all the necessary theoretical material in a single (or even couple of chapters) they text offers references to sources which cover certain topics in-depth -- for those readers who would like to dive deeper in machine learning. Finally, the book wraps with application of the discussed machine learning techniques to certain malware families.
