ITP2R21B 10-Pack 1 In. Phillips/Square #2 Impact Tough Screwdriving Insert Bits

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.

Absolutely love the perfect fit for #2 screws. It makes a difference when you use the right size and the bit is quality made. Far less frustrations with stripping and rounding. In fact it has enough grip to twist off a screw if you get in tough material, and then come back for many more. Well worth the price.

EXCELLENT bits!! Works on #2 Ph and #2 Sq

You pay a little extra for name brand products but it is worth it for reliable service. Ordered and shipped directly to job site. Arrived in time. Worked as expected.

These grip a Phillips screw better than any other bit out there. They are a bit faster wearing than other bits but it's worth it for the performance when they're new. They also fit a Robertson (square) drive screw quite well. I'm an electrician, a lot of screws we come across are Robertson, on top of how well they grip the screws, it's nice to have a bitbthat fits multiple types of screws.

How about these Bosch fits because I had bought some cheaper ones and they didn't hold up at all so I went back to Bosch bits and let's say I learned my lesson of buying cheap.

Love these bits they drive Phillips screws much better than a PH2. They really lick on to the screw. Combined with a magnetic bit holder they really lick on to the screw so you can focus on driving the screw.

It took me decades to find out that screws in outlets and switches are not normal Philips #2. They use screws that are a combination of a Philips and a Robertson or square bit. I have been using Leviton electrical outlets and sockets at home. Square bits cam out less then Philips bits. But a square bit cams out in the cheap junction box screws. The Bosch P2R2 fits better in the junction screws. The terminal screws are higher quality and either a Philips #2 or a square bit cams 1 fits well. So for both screws, you can just use the Bosch P2R2. A square or Robertson 2 won’t fit, so why they use R2 in the name is a mystery.

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.

Por enquanto usei somente com parafuso Philips, e foi muito bem.

Work well so far
