## Questions & Answers

**Q: What are the blade specs? We know its 4.5" but what is the center hole size?**
A: The arbor hole is 3/8" which makes the blades harder to find at the local hardware store. There is no adapter included, but also note that Dewalt clearly states not to use abrasive blades as that could overheat the motor.

**Q: What are the main differences between this and let's say the 7 1/4 inch circular saw? The cut depths are not that different.**
A: It barely cuts through 2x lumber (1-9/16) that's only a 1/16 over the depth of 2x lumber,  so I don't use it for that, personally. It's a wonderful "grab and go" saw for 1x material and sheet goods. I'm a homeowner weekend warrior user, so I'm not using it daily. But, so far it's cut through everything well and you can easily use it with one hand. I also have the 7-1/4 saw and use it when I cut 2x material as it will cut 1 inch deeper.

**Q: What's the part number for a compatible dust bag?**
A: A dust port is included to connect to a vacuum.   The port part number is N594300

**Q: can i use the dewalt battery from my cordless drill to power this saw?**
A: Yes, if the battery of your cordless drill is 20v also.  Batteries of all 20v tools, I believe, can be used to power any other 20v cordless tools.

Cette scie se manipule facilement et sans encombrement de fils puisqu'elle est alimentée par une batterie (qui n'est pas fourni lors de l'achat). Par contre, si tu possèdes déjà une ou des batteries Dewalt cet achat est parfait (moins cher qu'avec l'achat d'une batterie). Coupe très bien le bois avec sa petite lame. De plus, vu que celle-ci est plus petite, elle est moins lourde que les grosses scies circulaires. Cet outil a facilité nos travaux pour le patio, dans la maison. Le seul regret que nous ayons, moi et mon conjoint, c'est de ne pas l'avoir acheté avant. De plus, cette scie sera parfaite pour les petits travaux futurs, nous voyons cela comme un très bon investissement. Un achat fort utile et sans aucun regret car très bon produit pour la qualité/prix.
