I enjoy using the Dewalt DW OSC tool when I use their blades. I tried some cheap import knock-off blades and was greatly disappointed. Stay the course with the Dewalt blades. They cut smooth and last a long time. This kit gives one a good selection of blades that will meet most od your needs. Item was received on time and no damage.

Why in the heck did I wait so long to buy the tool and accessories.
What a time saver, easy to use and comes with replacement blades for different types of material.
Decent starter kit
Always great to have reserves on hand. Nice carrying case makes storage and transport easy.
Un peu cher, sinon parfait
My buddy lent me his tool to remove a rotten piece of decking. I found it so handy I bought one myself. It is an amaze tool. I also have several Dewalt tools so I already have the batteries.
