BOSCH GMA22 Auto Feed Attachment for GTB18V-45 Screwgun

Excellent addition to the GTB18v-45 screw gun. Compatible with most collated screw brands. I used SENCO and had no issues with feed.

I really wanted to like this along with the screw gun. I have other bosch tools so it was a no brainer really to get this. Plus I really liked how it fit the hand. Anyway I had to return this along with a separate purchase of the screw gun.My job uses robertson screws aka square heads. Bosch uses a specific size length of a bit to fit this.No one else makes that length sq head, so when I attempted to use my sq head bit in this, it wouldn't work. I was able to get it securely fitted but it wouldn't reach to drive. So I tried another sq head bit that was a little longer but than it would not grab the screws as it fed.I think bosch really missed hard on this, senco sells sq head clips and they move a lot of fasteners. Other brands have no issue using phillips, sq or torx (all which can be bought in clips) but bosch only works with phillips and their specific bit length. Ended up getting another brand and screwed an entire camper roof down no problems. I thought about giving it 1 star but it really is a 5 star product if you only did drywall, which I don't.The worst issue is the specific length bit and shank diameter, they really pigeon hole you on that.You can't even use your favorite brand that you want to use or just buy any brand and use it.I tried a kreg bit and a metabo bit ,none of them worked, I really did try Bosch..Maybe make a bit that can do both? You already sell that style, just make it longer to fit your attachment.But It's too late, the brand I picked up should last as well as the bosch would have.

After much research I decided to give this Bosch screw attachment a shot. First a little background. I've done construction form most of my adult life. Tools aren't just a hobby, it's how I make a living! So, not an amateur by any means! I purchased this item GMA-22 along with the Bosch screw gun GTB18V-45B15. I have limited batteries for Bosch tools so I bought another battery so I would have a spare on hand. With that said!Assembly:I promptly unpacked everything and put everything together. Everything goes together easy! Taking things apart however will take a bit of muscle. Make sure you are standing near anything or anyone you don't want to hit of damage when you go to remove the nose or the attachment. Why? Well, these attachments are friction fit and fit very snug. When they parts pop a part there will be significant force that could injure ones self or a near by person. Once I had everything together and read through all the instructions I proceeded to a test wall.Testing:I double checked everything to ensure I was ready to go. I carefully aligned myself and commenced screwing. Out of the gate I noticed that the first screw skipped if you follow the instructions. Not a big deal. So I carried on. The screws seemed to misalign often with the bit causing the screw to flop to side ways. This happened about every 4th or 5th screw. This could be caused by what appears to be poor alignment of the attachment to the tool. I continued on. Less than a minute in the gun got stuck on randomly pulsating. I was able to correct this by removing the battery and the attachment and reassembling. This happened a few times. After the 3rd jam/stuck on condition I shut it down and opted to return the items purchased for this attachment. It's a real shame. The gun seems to work fine on it's own. But, I prefer collated screws to speed up my work and fun!I really want to like Bosch tools. I love the colors! However, this is the second time I experimented with Bosch tools. I have an 1/2" impact from Bosch as well. It broke on the first day of use. I sent it out for repair and received it back a month later. It now sits in my tool box next to the Milwaukee I had to buy to do the job I bought the Bosch for. The Milwaukee impact works flawlessly! Just an FYI!I will stick to Dewalt and Milwaukee for most tools for now. Bosch, get your shit together! I want to turn my tool boxes and garages Bosch blue. The only thing stopping me is Bosch Quality!Assembly 10/10Disassembly 5/10Function 2/10
