There was also a corresponding set only from Philips. I thought I would get these so that I have the straight one as well. Oops, they don't fit in the hexagonal chuck of the electric screwdriver! With the slightest resistance, they start jumping and spinning around themselves, especially when the straight one is from the inside. They don't even fit in a chestnut screwdriver. They fit and tighten properly in a regular chuck from a drill driver.

I intended to rate lower, BUT!
Most people use a drill driver with the classic open-close chuck. Maybe the hexagonal chuck is more convenient for me and I buy drills for it, but the product deserves four stars because it will meet the needs of most people. Besides, these bits are impact bits, and in impact mode, the classic chuck is far safer.

I just hoped for something longer than the 50mm ones I already have. I will probably have to go for the 90mm ones.
