Ryobi ONE+ HP Drill
Score: 80/100Rankings

The Ryobi ONE+ HP 18V Cordless Compact Brushless 1/2" Drill/Driver (PSBDD01) is a lightweight, compact tool designed for tight spaces and overhead applications, offering 400 in-lbs of torque in a package that is 30% smaller than its predecessor. It features a brushless motor for extended runtime and life, fitting into Ryobi's extensive 18V ONE+ ecosystem of over 300 compatible tools. While excellent for DIYers and homeowners needing a portable solution, it lacks the sustained power required for heavy-duty professional construction work.

The DeWalt DCD777B is a compact, lightweight 20V MAX brushless cordless drill/driver designed for versatility in DIY and professional applications. It features a 340 UWO power output and a ratcheting chuck, making it suitable for drilling and driving tasks in tight spaces. While it offers good portability and runtime, the lower max RPM and plastic chuck are notable trade-offs for heavy-duty users.

Professional reviewers acknowledge the DCD777B as a solid, well-built unit with good ergonomic design. However, the primary limitation cited is the maximum RPM of 1,600, which falls short of competitors, along with concerns about the plastic ratcheting chuck's durability.
Users maintain a generally positive reception, praising portability and ergonomic balance. Common concerns include the limited RPM and worries about the plastic chuck's durability under heavy use.

Professional reviewers highlight the Ryobi PSBDD01 as a highly capable compact drill that punches above its weight class. Pro Tool Reviews noted that the brushless motor delivers plenty of power for a compact drill, with a meaningful 50 in-lbs improvement over the previous generation. Independent technical reviews praised the excellent thermal performance, noting that heat management remains stable during both light prolonged use and heavy intermittent use. Reviewers also commended the comfortable design, new overmold grip, and the utility of the 24-position clutch for precision work. Marketing emphasizes its status as the most compact RYOBI Drill/Driver with the advantages of brushless technology.
Everyday users consistently praise the drill's ability to fit into cramped spaces and its lightweight nature, which reduces fatigue during overhead work. DIYers report that it handles general home repairs, furniture assembly, and light construction without issues. The ecosystem value is a major positive, with users appreciating the compatibility with over 300 ONE+ tools. However, recurring complaints include the tool's inability to handle heavy-duty work, the short runtime of the included 1.5Ah battery, and the lack of continuous variable speed. Many users note that it is not professional-grade and may hit torque ceilings when working with hard materials.
