DEWALT DCH133B Hammer Drill Review Reveals Power and Precision in Compact Design

Description

Highlights of the DEWALT DCH133B 20V Max XR Brushless Rotary Hammer Drill

Using the DEWALT DCH133B 20V Max XR Brushless 1-Inch D-Handle Rotary Hammer Drill has been quite an experience. This cordless hammer drill stands out with its optimized 2.6J mechanism, which delivers a remarkably fast speed of application—sometimes even faster than some corded models I’ve worked with. The brushless motor ensures durability and efficient power management, making it easy to maintain speed without bogging down, even when using larger drill bits. The compact design, notably its D-handle, allows me to access tight spaces where bulkier tools struggle, which came in handy for some intricate drilling jobs around the house.

Good Aspects

• Brushless motor technology provides longer runtime and reduced maintenance.
• The cordless design offers freedom of movement, eliminating the hassle of cords during work.
• Compact and ergonomic, making it easier to handle in confined areas.
• Maintains consistent speed even under heavy load thanks to DEWALT’s advanced electronics.

This tool impressed me with how well it balances power and portability. The 20V MAX XR battery platform (although sold separately) gives enough juice to power through concrete and metal drilling tasks without overheating or losing momentum. It’s a solid choice for anyone wanting a reliable rotary hammer without the tether of a cord.

Drawbacks

• The fact that the battery and charger are sold separately can be a bit frustrating, especially if you don’t already own compatible DEWALT batteries.
• At nearly 6 pounds, the weight feels a bit hefty for extended overhead work.
• While compact, the D-handle grip might not suit everyone’s hand size, leading to some discomfort during prolonged use.
• The 90-day limited warranty feels short compared to other tools in this power range, which might concern those investing in professional-grade equipment.

I noticed that the tool’s weight becomes noticeable when used for longer periods, especially in awkward positions. Additionally, the absence of included batteries means the initial investment could be higher if you’re starting from scratch. The warranty also leaves me wishing for a bit more peace of mind.

Performance and Versatility

This rotary hammer drill excels in versatility. Its hammer drill mode, rotary-only mode, and hammer-only function cover a broad spectrum of construction and DIY needs. I tested it on wood, metal, and concrete, and it handled all materials admirably. The maximum drilling capacity is impressive: up to 16 millimeters in wood and about 20.7 millimeters in metal. The power output feels consistent, and the tool doesn’t bog down even while drilling larger holes.

The brushless motor is quieter than some older models I’ve used, which is a welcome change when working in residential areas or indoors. The vibration control is decent, though extended use still fatigued my hands, probably due to the tool’s weight. The compact size also helped me drill in tight corners where my previous rotary hammer wouldn’t fit.

Price Worthiness

This tool’s price to quality ratio seems fair when considering the build quality and performance. While the bare-tool option means you have to factor in separate battery and charger purchases, the overall investment delivers a professional-grade experience. Compared to other cordless rotary hammers in this power class, this model offers solid durability and power without unnecessary bells and whistles.

If you already own compatible DEWALT batteries, this tool becomes an even better deal. Its energy efficiency and runtime mean fewer battery swaps on the job, which saves both time and money in the long run. For DIYers and professionals alike, it’s a worthy addition to your toolkit, especially if you prioritize freedom of movement and compactness.

Competing Brands and Models

The DEWALT rotary hammer drill faces strong competition from brands like Milwaukee, Bosch, and Makita. For instance, Milwaukee’s M18 Fuel rotary hammer offers similar power but includes a longer warranty and sometimes better vibration reduction. Bosch’s cordless rotary hammers often boast lighter weight, though they might lack the same punch in hammering power.

Compared to these rivals, this drill excels in speed of application and maintaining torque under load, thanks to the DEWALT electronics. However, the weight and shorter warranty place it slightly behind some competitors in user comfort and after-sales assurance. If battery ecosystem compatibility is a deciding factor, DEWALT’s widespread 20V MAX platform is a clear advantage, especially for users already invested in those tools.

Design and Usability

The yellow and black color scheme is classic DEWALT, making it easy to spot on a busy job site. The D-handle design improves grip security, but users with smaller hands might find it a bit bulky. The controls are intuitive: a well-placed trigger and mode selector make switching between hammer, drill, and hammer-only modes quick and hassle-free.

This hammer drill doesn’t come with many accessories in the box, being a bare-tool model, so I had to rely on my own bits and batteries. The 20-millimeter chuck size accommodates a wide range of drill bits, adding to its versatility. The overall build feels robust with a combination of plastic and metal materials, giving me confidence that it can withstand rough job site conditions.

Additional Features and Considerations

One feature I appreciated was the electronics that prevent the tool from bogging down, which really shines when drilling through tough materials. The runtime efficiency is boosted by the brushless motor, which also helps keep the tool cooler during extended use. The drill’s dimensions—16 inches long, 8.5 inches wide, and about 4 inches high—make it manageable but still substantial enough to feel powerful.

This rotary hammer drill doesn’t include a battery, charger, or case, so buyers must consider those additional costs. The 5.96-pound weight feels balanced but can be tiring when working overhead or in awkward positions. Also, the limited 90-day warranty might raise eyebrows for those expecting longer coverage on a power tool in this price range.

Summary of Positive Features

• Robust brushless motor technology enhancing durability and runtime.
• Compact size for access to tight, restricted spaces.
• Maintains speed and power even with larger drill bits.

Summary of Negative Features

• Requires separate purchase of battery and charger, increasing upfront investment.
• Relatively heavy, which may cause fatigue during prolonged use.
• Short warranty period compared to similar tools.
