The variable speed trigger offers control, and the tool-less blade change simplifies use. Its compact size is a major advantage in tight spaces, but it lacks the power for heavy demolition. Owners love its portability and battery life for light work.
Pros
- Ultra-lightweight
- Ideal for tight spaces
- Good battery life for 12V
Cons
- Not for heavy-duty cutting
- Short stroke length
Milwaukee M18 FUEL Sawzall (2621-20)
The Milwaukee 2621-20 is a full-size brushless Sawzall that delivers extreme cutting power with up to 3,000 SPM and a 1-1/8-inch stroke. Its POWERSTATE motor and Redlink Plus Intelligence provide optimized performance, durability, and overload protection. The anti-vibration system reduces user fatigue, and the adjustable shoe allows for extended blade life. Owners praise its cutting speed and reliability for demolition and framing. It is heavier than compact models, but the power compensates.
Pros
- Powerful cutting performance
- Long 1-1/8-inch stroke
- Durable construction
Cons
- Heavy and bulky
- Higher cost
DEWALT ATOMIC 20V MAX Reciprocating Saw (DCS312B)
The DEWALT DCS312B is a compact brushless reciprocating saw that offers a balance of performance and affordability. It delivers up to 3,100 SPM with a 3/4-inch stroke, making it suitable for general cutting tasks. The variable speed trigger provides control, and the tool-free blade clamp allows quick changes. Weighing only 6.9 lbs, it is easy to handle. Owners appreciate its price point and decent performance, but note that the shorter stroke makes it less efficient for large lumber.
Pros
- Affordable brushless option
- Lightweight
- Variable speed trigger
Cons
- Shorter stroke length
- Less powerful than full-size models
Ryobi P516 18V ONE+ Brushless Reciprocating Saw
The Ryobi P516 is a brushless reciprocating saw designed for the 18V ONE+ system. It delivers up to 3,100 SPM with a 1-inch stroke, offering good power for DIY projects. Its variable speed trigger and tool-less blade change add convenience. Owners like the bright LED light and the rafter hook. It is a solid choice for those already invested in Ryobi tools, but it does not match the build quality of premium brands.
Pros
- Compatible with ONE+ batteries
- LED light for visibility
- Affordable price
Cons
- Build quality not as premium
- Battery and charger sold separately

Before you buy
Common questions
What is a brushless motor and why is it better?
A brushless motor uses electronic commutation instead of physical brushes. It is more efficient, producing more power and longer runtime, and lasts longer because there are no brushes to wear out.
Can I use a brushless reciprocating saw for demolition?
Yes, full-size models with long stroke lengths and high SPM are suitable for demolition. Compact models may struggle with thick materials but can handle light demolition tasks.
What is the difference between a reciprocating saw and a Sawzall?
Sawzall is a trademarked name for a reciprocating saw by Milwaukee. It has become a generic term for reciprocating saws, similar to how Kleenex is used for tissues.
How do I choose the right blade?
Select a blade based on the material you are cutting. For wood, use a blade with 3-5 TPI (teeth per inch). For metal, use a blade with 10-14 TPI. Bi-metal blades are versatile and last longer.
Are brushless reciprocating saws worth the extra cost?
For frequent users and professionals, yes. Brushless motors offer better performance, efficiency, and lifespan. For occasional DIY use, a brushed saw may be sufficient and more economical.
What safety features should I look for?
Look for electric brakes, which stop the blade quickly when you release the trigger. Anti-kickback clutches prevent the saw from jerking if the blade binds. Also, a good shoe adjustment helps maintain control.
Can I cut metal with a reciprocating saw?
Yes, with the correct blade. Use a high-TPI blade specifically for metal. Lubricating the cut with cutting oil can extend blade life and improve performance.
How important is weight when choosing a saw?
Weight affects maneuverability and fatigue. Compact models around 7 lbs are easier to handle and are better for overhead or one-handed use. Full-size models are heavier but offer more power.
Do all brushless reciprocating saws have variable speed?
Most do, but some compact models may have a two-speed switch instead of a variable trigger. Check the specs before buying to ensure it has the control you need.
What is the best way to prolong battery life?
Store batteries at room temperature, avoid extreme heat or cold, and do not discharge them completely before recharging. Use the correct charger for your battery type.
Final word
For most users, the Milwaukee M18 FUEL Hackzall offers the best combination of portability and performance, making it our overall top pick. If you need maximum power for heavy demolition, choose the Milwaukee M18 FUEL Sawzall. For budget-conscious DIYers, the DEWALT DCS312B is a solid value.
