Which one should you choose?
Choose Bosch Bulldog Xtreme 1-Inch SDS-Plus Rotary Hammer if
- You need a lighter tool for drilling smaller holes in brick or concrete.
- You prefer a compact handle for better maneuverability in tight spaces.
- Your projects involve standard masonry work that does not require heavy chipping.
Choose VEVOR 1-9/16-Inch Corded SDS-Max Rotary Hammer if
- You are demolishing thick concrete or need to drill large diameter holes.
- You require higher impact energy for breaking up hard materials.
- You want a tool with adjustable speed settings and vibration control for extended use.
Verdict: The Bosch SDS-Plus model suits homeowners and professionals doing routine drilling and light masonry. The VEVOR SDS-Max tool is built for heavy-duty demolition and large-scale concrete work. Select the bit system that matches the size of your holes and the hardness of your material.
SDS-Plus vs SDS-Max Power
Bit Type Compatibility
The Bosch Bulldog Xtreme uses an SDS-Plus bit system with a 1-inch chuck. This standard size fits a wide range of common drill bits and chisels for light to medium masonry work. The VEVOR model uses an SDS-Max system with a larger 1-9/16-inch chuck. SDS-Max bits are physically bigger and stronger, designed for heavy-duty demolition and larger diameter drilling. You must buy specific bits for each tool. Neither system is universally compatible with the other without adapters, which can affect performance. Your choice depends on whether you need standard bits or heavy-duty ones.
Impact Energy
Impact energy determines how much force the tool delivers to break through hard materials. The Bosch Bulldog Xtreme delivers 2-1/5 foot-pounds of impact energy. This is sufficient for routine tasks like drilling holes in concrete blocks or light chipping. The VEVOR model provides 10 Joules of impact energy. Since one foot-pound is roughly 1.35 Joules, the VEVOR offers significantly higher force. This extra power helps the VEVOR tackle dense concrete and larger demolition tasks more efficiently. If you need raw breaking power, the VEVOR is stronger.
Motor Power
Motor amperage indicates the electrical power drawn by the tool. The Bosch Bulldog Xtreme has a 7-1/5-amp motor. This moderate power level is typical for SDS-Plus tools, balancing performance with manageable heat and weight. The VEVOR model features a 13-amp industrial motor. This higher amperage supports the greater impact energy and heavier duty cycles. The VEVOR also mentions a heat-resistant copper wire motor to handle longer work periods. For continuous heavy use, the higher amperage of the VEVOR suggests it can sustain higher loads better than the Bosch.
Blows Per Minute
Blows per minute (BPM) affects drilling speed in softer materials and chipping efficiency. The Bosch Bulldog Xtreme reaches up to 5,800 BPM at no load. This high frequency allows for faster drilling in brick or soft concrete. The VEVOR model operates at a maximum of 3,600 BPM. While lower, this rate is paired with much higher impact energy per blow. The Bosch is better for speed in standard drilling tasks. The VEVOR prioritizes force over frequency, which is often more useful for breaking up hard concrete.
Weight and Portability
Weight affects user fatigue during overhead or prolonged use. The Bosch Bulldog Xtreme weighs 11.5 pounds. This lighter weight makes it easier to handle for extended periods or in tight spaces. The VEVOR model weighs 16 pounds. The additional weight comes from the more robust motor and heavier-duty internal components. While the VEVOR includes vibration control to reduce injury, the extra mass still requires more strength to maneuver. For tasks requiring frequent repositioning or overhead work, the lighter Bosch is easier to manage.
Which SDS Rotary Hammer Fits You
Light duty masonry and drilling tasks
The Bosch Bulldog Xtreme delivers 2-1/5 ft-lbs of impact energy with 0-5,800 BPM. Its 11.5 lb weight and 1-inch SDS-Plus chuck make it manageable for standard holes in brick or light concrete. You get variable speed control and a D-handle for better grip during precise, smaller-scale projects.
Heavy demolition and large diameter holes
The VEVOR model offers 10 Joules of impact energy and a 13 Amp motor. It accepts 1-9/16 inch SDS-Max bits for large holes or chiseling. The 16 lb weight and vibration control help manage fatigue during long demolition sessions or heavy-duty concrete work requiring significant force.
Users needing adjustable speed and modes
You can switch between hammer only and hammer drill modes on the VEVOR unit. It features a speed control system with six settings, reaching 3,600 BPM. The 360-degree adjustable handle and vibration control provide comfort and flexibility, making it suitable for varied professional tasks that require precise power adjustment.

Frequently asked questions
Can I use SDS-Max bits in an SDS-Plus hammer?
No. The shank designs are incompatible. SDS-Plus chucks, like the 1-inch size on the Bosch Bulldog Xtreme, accept only smaller SDS-Plus bits. SDS-Max bits have a thicker shank that will not fit into the smaller chuck. Forcing the wrong bit can damage the tool.
What is the weight difference between these two tool types?
SDS-Max tools are significantly heavier. The VEVOR SDS-Max model weighs 16 pounds. In contrast, the Bosch SDS-Plus model weighs 11.5 pounds. The extra mass in the SDS-Max design helps with heavy demolition but reduces maneuverability for lighter tasks.
Which bit type handles larger diameter holes?
SDS-Max handles larger holes. The VEVOR SDS-Max rotary hammer supports bits up to 1-9/16 inches. The Bosch SDS-Plus model uses a 1-inch chuck, limiting its maximum bit size. Choose SDS-Max if you need to drill wide holes in concrete.
Is SDS-Plus suitable for home renovation projects?
Yes. The Bosch Bulldog Xtreme is ideal for standard masonry drilling and light chipping. Its manageable weight and 1-inch SDS-Plus chuck make it easy to handle for homeowners. It fits users who need reliable performance without the bulk of larger industrial tools.
Does the VEVOR model run on battery power?
No. The VEVOR 1-9/16-Inch model is a corded rotary hammer. It requires a power outlet rather than a battery pack. This design delivers consistent power for heavy demolition and large-diameter drilling tasks without worrying about battery life during tough jobs.
Which tool is better for heavy demolition?
The VEVOR SDS-Max model is better for heavy demolition. It delivers serious impact force suited for tough jobs. Contractors who prioritize power over lightweight convenience will find this model more effective for breaking concrete compared to the lighter SDS-Plus alternative.
