DeWalt DCH133B 1 inch

Expert Review Analysis

The DEWALT 20V MAX 1-in. SDS Plus Cordless Rotary Hammer (DCH133B) is a brushless, lightweight tool designed for concrete drilling and light demolition. It delivers 2.6 Joules of impact energy through a German-engineered mechanism, offering corded-like power in a compact D-handle form factor. The tool features a 3-mode rotating dial for drilling, hammer drilling, and chipping, making it suitable for structural connections and anchor installations.

✓ Best for: Professional contractors, electricians, plumbers, and framers needing portable power for medium-duty concrete work. Specific use cases include forming and rod hanging, structural connections, beam and column anchorage, steel stanchion mounting, clip and bracket installs, and mechanical anchor holes in concrete or masonry up to 1-inch. It is also ideal for overhead or tight-space drilling where weight and compactness matter.✗ Not ideal for: Heavy chiseling tasks or heavy demolition work where higher impact energy is required. It is also not ideal for ultra-light tasks where the Atomic line's lighter weight is preferred over the DCH133B's higher power output.

Pros

✓Delivers 2.6 Joules of impact energy for faster concrete drilling than many cordless rivals

DCH133BYeifOne Size 3 year limited warranty

Brushless motor provides efficient power usage and extends runtime during heavy use

✓Compact and lightweight design allows for easier operation in overhead or tight spaces

✓Versatile 3-mode rotating dial enables switching between drilling, hammer drilling, and chipping

✓German-engineered mechanism ensures reliability and durability for tough applications

Cons

✗Lacks active vibration control features found in higher-end XR models like the DCH273
✗Heavier bare weight compared to Atomic compact models which weigh around 3.56 lbs
✗Does not include E-CLUTCH anti-bind safety feature present on some higher-tier models
✗Tool-only model requires separate purchase of batteries and charger for immediate use
✗Side handle may slip occasionally when used in wet concrete conditions

From Expert Reviews

Praised by Experts

✓Provides ideal power for forming, rod hanging, and anchor installations due to 2.6J output
✓Lightweight construction reduces user fatigue during all-day professional use
✓Brushless efficiency and durable mechanism extend overall tool runtime and lifespan
✓Compact size allows access to restricted areas where larger tools cannot fit

Criticized by Experts

✗Absence of active vibration control may lead to quicker user fatigue during extended use
✗Lacks advanced safety features like E-CLUTCH found in more expensive professional models
✗Not OSHA Table 1 compliant compared to specific XR variants with extractor compatibility

From User Reviews

Users Love

✓Drills through concrete quickly with power comparable to corded rotary hammers
✓Lightweight nature makes overhead work significantly less tiring for the user
✓Long runtime is achieved when paired with high-capacity 6Ah battery packs
✓Versatile modes save time by allowing quick changes between drilling and chipping tasks

Users Complain About

✗Noticeable vibration causes hands to tire after drilling more than 30 holes without protection
✗Battery drains quickly when operating in maximum hammer mode requiring larger capacity packs
✗Side handle slips occasionally when the tool is used in wet concrete environments

Expert Opinion

Professional reviewers and editors highlight the DCH133B's impressive power-to-weight ratio, noting that its 2.6 Joules of impact energy makes it ideal for structural connections, rod hanging, and mechanical anchors. Editors praise the German-engineered mechanism for its reliability and the brushless motor for extending runtime. While it is commended for its compact design and ability to perform tasks quickly, some analogs note that it trades advanced safety and vibration control features for affordability and portability.

What Users Say

Everyday users frequently praise the tool for its ability to blast through concrete with speed comparable to corded models, making it highly effective for anchors and brackets. The lightweight design is a major plus for overhead work, though users note that runtime is heavily dependent on using 6Ah or larger batteries. Recurring complaints focus on the lack of vibration control, which leads to hand fatigue after extended use, and occasional slipping of the side handle in wet conditions.

Common Complaints

Users report noticeable vibration leading to hand fatigue after drilling more than 30 holes, rapid battery drain when using maximum hammer mode, and occasional slipping of the side handle in wet concrete.

How It Compares

vs. DEWALT DCH273B

Advantages

✓Higher 2.6J power output compared to DCH273's 2.1J

Disadvantages

✗Lacks SHOCKS active vibration control and OSHA compliance found in DCH273

Choose the DCH133B for higher raw power and lower cost, or the DCH273B for reduced vibration and regulatory compliance.

vs. DEWALT DCH293B

Advantages

✓Lighter weight and lower cost than the heavier DCH293B

Disadvantages

✗Lower impact energy (2.6J vs 3.5J) and lacks E-CLUTCH safety feature

Choose the DCH133B for lighter, cheaper 1-inch work, or the DCH293B for maximum power and safety in large hole applications.

vs. DEWALT DCH172 (Atomic)

Advantages

✓85% more power (2.6J vs 1.4J) and full 1-inch capacity vs 5/8-inch max

Disadvantages

✗Heavier bare weight compared to the ultra-light 3.56 lbs Atomic model

Choose the DCH133B for serious concrete drilling needs, or the DCH172 for ultra-light, occasional tasks where weight is critical.

vs. Milwaukee M18 Fuel 1"

Advantages

✓Superior 2.6J impact energy and perceived DeWalt durability compared to ~2.0J Milwaukee

Disadvantages

✗Lacks the potentially better battery ecosystem integration of Milwaukee REDLINK

Choose the DCH133B for higher impact power and DeWalt brand preference, or Milwaukee for ecosystem integration.
