Ces mèches ne percent pas le bois, juste sur 1 à 2 mm de profondeur !!! Lot inutilisable.

Great well designed product, that makes making holes in most timber as easy as slicing butter.Have been using these daily for a few months and still reasonably sharp... Even after hitting a few nails.Would recommend for anyone needing a decent set of bits.

الي يميز هالنوعية انها تخترق بدون ما تسوي ضغط لأن راسها فيه سكرو , قوية جدا والماركة اير ون غنية عن التعريف

These 3 wing bits are so much better than spade bits. They're faster, they clear chips much better, and they are much less likely to jam up. They do require a drill with some torque, though. A good 3/8" cordless will run up to 3/4" easily, but I think a 1/2" drill is probably a good idea for 1" bits. If you have a side handle, use it.The 4" length is great, because it's plenty to get through 2x lumber, and it's short enough that many regular drills have plenty of room to drill between 16" studs, so you don't need a right angle. With a right angle drill, it'll get into some tight spots.This isn't a woodworking bit, so it will often/usually not make a pretty exit. It's for construction work. I've run the 6" size on extension to fish in ceilings, and they work great for that. The recesses allow the extension to lock onto the bit, so much less risk of losing it. Much better and faster than extensions that use set screws.
