## Description

Bosch impact tough impact driver bits have been upgraded to deliver 10x life over standard impact bits. With an xtended torsion zone, precision engineering and heat-treated manufacturing process, These bits deliver tough torque and power for longer – and with less CAM out. These impact tough bits are an impact-rated line of screw driving bits, double-ended bits, nut setters, sockets and bit holders that have been enhanced to handle a new generation of higher torque impact drivers. These bits also come with high-visibility sleeves for greater user convenience.

Review: Too good to be true - A standard square drive head fits into the screw snugly. It'll stay there for an eternity without falling off. Climbing a ladder, getting down on your knees, it'll not move from the drill. These contraceptions need alot of force behind them to stop them slipping in the screw head. Never in my life have I seen a square drive impact bit slip inside a screw, but today I seen it plenty. The screw doesn't stay on the bit either, it falls off. It's like a drunken sailor wobbling all over the place. This was another first for a square drive screw. I would genuinely rather buy a second driver and use both impact bits, before using these again. They're absolute dog poo.
Review: Por enquanto usei somente com parafuso Philips, e foi muito bem.

*by C***H on 14 March 2026*

These were a bit smaller than I thought they would be, mostly in diameter, but they have worked just fine for my uses. This bit is probably the best phillips type bit I've ever used, especially on aluminum screws (aviation, IYKYK), they have very good grip and have had WAY less issues with skipping/stripping.
