Tool Review Makita JR3050T $78 A well-built but slightly underpowered saw. It has surprisingly good ergonomic features that enrich a truly well priced tool. 800-462-5482 46 Milwaukee 6509 Milwaukee invented the reciprocating saw and maintains a major presence in this market, with seven corded models. Although the 6509 is at the bottom of the family tree, there's no doubt that it shares a significant percentage of its DNA with other Milwaukee recips. Its heavy-duty double-insulated construction, thick rubber-coated electrical cord and hefty 5/8"-diameter blade shaft are all elements found on more expensive Milwaukee models. Other than a variable-speed trigger, the 6509 is a Spartan saw: there's no blade orbit adjustment, LEDs, etc., and this is the only saw in the group that doesn't come with a case or tool bag. I did like Milwaukee's no-nonsense QUIK-LOK* blade clamp, which opens with a simple twist of its cylindrical body and then holds the blade very securely. The 6509 has a very heavy-duty foot that is adjustable, but you have to loosen four screws with an Allen wrench (not included with the saw) — a time-consuming process. Although the Milwaukee is one of the lightest saws in this group, it boasts a powerful 11-amp motor. But, as I've discovered in other power tool tests, motor amperage alone isn't a good indicator of performance: Although the Milwaukee breezed through plastics and thin metals, the saw's 2x8 cutting time of 22.25 seconds was the slowest of the bunch, perhaps due to the tool's short 3/4" cutting stroke. On a happier note, the 6509's double-bearing wobble plate helped to reduce vibration, putting it neck-and-neck with the Bosch in terms of overall cutting smoothness. full use from the teeth of the provided 7"-long bi-metal, progressive tooth blade. Although the Hitachi lists "electronic feedback power control" to keep the RPMs up during heavy cutting, the CR13V turned in a middle-of-the-pack performance, requiring 17.75 seconds to crosscut the 2x8s in my test. But the real deal breaker for me was Hitachi's bone-jarring vibration, making it the saw I least liked to use. Makita JR3050T As the least expensive saw in this test (by only $1) with only a 9-amp motor and 1" cutting stroke, my expectations for the Makita JR3050T were modest. But this well-built saw, with ball and needle bearings and "dust-proof construction, proved to be a decent performer. The Makita ran a respectable time of 17 seconds in the 2x8 cutting test, generating vibrations on par with the DeWalt. The JR3050T has an overmold on its grip that adds a degree of user comfort as well as a wide trigger (only the DeWalt and Milwaukee have single-finger triggers) which helps prevent index-finger strain. There's a lock-on button for the trigger as well, to save fatigue during prolonged cutting. The saw's built-in sawdust blower creates a blast of air from the motor's fan. Unfortunately, the air does not blow sawdust from around the line of cut, so it's not a useful feature. At first, I was impressed with the Makita saw's blade clamp, which has a comfortable-to-grip rubber overmold and locks open, making blade changes very easy. But if the saw stops with the blade fully retracted, you can't reach or operate the clamp. Definitely irritating. The Maldta does boast the easiest tool-less foot adjustment of any recip saw: A simple push button secures the foot, which sets to any of five different positions. 6509 $106 A Spartan saw with a great heritage. Low vibrations and a variable speed trigger were features that enhanced this tool's work. 800-729-3878 Tool Review continues on page 50... August 2009 Woodworker's Journal |
