Choosing Between the Milwaukee 2420-20 & 2520-20 HACKZALL
Choosing between the Milwaukee 2420-20 and 2520-20 comes down to how often you cut and what you cut through, not top speed, since both reach up to 3,000 strokes per minute. The 2420-20 fits occasional, lighter jobs, while the 2520-20 is built for frequent or demanding use.
Most buyers overpay by defaulting to the pricier model. The 2520-20's POWERSTATE brushless motor earns its higher cost only when you cut often or work through tougher material, where cooler running and steadier power pay off. For light drywall, wood, or PVC work, the standard 2420-20 does the same job for far less.
GenuineTools offers new, factory-sealed Milwaukee® Hackzalls and accessories priced well below the manufacturer's suggested retail price (MSRP), so you can match each saw to your workload without paying for features you won't use.
