Torx Bit Set with 1/4 inch Magnetic Bit Driver,TEKPREM 12-Piece Security Torx Screwdriver Bit Set with 1 inch T5 T6 T7 T8 T9 T10 T15 T20 T25 T27 T30 T40 Tamper Resistant Torx Bits Set

At first, I was concerned about the hole in the bit. I was hoping for a solid core tool because I use these on CNC Lathe machines whose screws can get tough to remove after much use.Wow was I wrong. These bits have held through rigorous use even with high torque stress. On one screw, I thought I had busted the bit...Nope. I stripped the metal of the screw. (Bad day. Don't ask. ha-ha)Don't worry about the term 'Security'. That's just the hole in the middle for removing bolts that have a 'security' pin in them. These bits work on any Torx screw. (Maybe not good for wood screws though.)The magnetic bit driver is comfortable to hold. Rubber grips on the handle help keep your hands from slipping.The magnet is strong enough to hold both the bit, and often the screw on the bit. Very nice feature.These bits are well worth getting. Especially if you don't need them to break high stress screws.Highly Recommend.

I would highly recommend I use this all the time on everything I put together

Good set for all sizes of the torx security bits. I have used it a few times and it seems to be well made. Would definitely recommend.

I purchased this magnetic ratcheting screwdriver and the accompanying bit set hoping the magnet would be strong enough to hold the bits in place during use. Depending on what they're used for, sometimes the bits remain in place and sometimes they fall out.

update after half year: the rubber on grip is starting to break. kinda expect it to last longerit works pretty well. the head for screw are made of magent so it stick to the handle pretty well. I like the desgin
