I bought a Snap On PH3050B with a half dozen or so bits. I kept the bits but dumped the PH3050B once I got my hands on an Atlas Copco RRH08P-TS air riveter. The Atlas is half the weight, more powerful, and more controllable than the PH3050B. The only thing you lose is the quick chuck. Look for the RRH08P-TS used on eBay. It makes the Snap On seem like an overweight noise maker. The Atlas knocked studs out of an exhaust pipe that the Snap On would not budge. For even more power, look to a CP717, or the Astro linked above. The CP717 and Astro Big Nasty take .498 Parker shank bits. The Snap On PH3050B uses .401 Parker shank bits.
