Used this to allow it to work in my magnetic handle. Problem is the thing does not work in my little dewalt gyro screwdriver. It will not lock in. I have tried dozens of different tips from every maker and this is the only one to not work in my power driver. Luckily I don't use this .05" tip in a power tool. If I were to setup with vanquish bit, they are not compatible with dewalt chucks.
