is the 51mm inside diameter or outside diameter

That is the outside diameter. I am not sure what you mean by the inside diameter. The tamper base is flat, so technically there is no inside diameter. I do like the weight of the tamper. It makes fast work of tamping down the grounds.

The "business end" of the tamper is 51mm across, side to side. There is no inside/outside diameter, if I understand your Q correctly. It is a straight line from top to bottom...no inside/outside. It's 51mm on top, and 51mm on the bottom. Hope this helps.

The side are pretty much straight up (90 degrees) from the bottom. there is no taper ,so I believe the inside and outside diameter is the same. We love ours, nice and heavy, solid feel.

It is 51 mm across. It works great with many of the smaller breville Espresso. It fit my Ec702 perfectly. The weight is good and makes a great better tamp than the ones provided with your machine. Well worth the price!

Hi, my fits the 52mm. Quality quite disappointing, espcially the edges of the picture, all blurred but still can live with it.

Outside diameter about 2 15/16" about 6/16" wide 2 3/16 inside diameter. To the best of my ruler.

I own the 51101 and my mother owns the 51103, so I have used both for making smoothies of frozen berries, juice, protein powder, and ice. In my experience, the difference is that the wider 51103 actually allows for ice to get stuck and not blend properly. The narrower 51101 restricts the ice's lateral movement, so it can't get lodged next to the blade. If you're doing anything with ice, or similarly sized frozen things, 51101 is the better option.

Actual answer: 49mm is the closest commercial. This is just about 2 inches and a smidge, so very close to 51mm. Another answer said 5mm, but they mixed up cm with mm.

This is not going to fit. I physically measured mine, the inside diameter is only 65mm.

A 51mm tamper works very well - I got one on Etsy. By my measurement, the inside of each portafilter basket is 52mm, and the 51mm tamper fits them both snugly with a tiny bit of wiggle room.

The outer diameter of the gasket is 2.5 inches. The inside diameter is 2 inches. Hope this helps.

The inside diameter is somewhere between, but closer to 1/4" than 3/8. According to my ruler, it looks like 9/32!

The lens cap is stamped 52mm. Where the cap snaps on and fits my SX20IS measures 51mm.

Measure in millimeters across the inside diameter of the outer front ring of the lens.

The inside dimensions of the case are 9.75 inches long by 4" wide (diameter). Your 500mm will definitely NOT fit. Sorry.

I think its a 29mm...as the 33mm is a 150cc.. There should be an item description which should tell the size

The inside diameter of my O-ring is 4.7 cm, the outside diameter is 6.7 cm. I don't have the model # of my machine. I ordered it directly from Hamilton Beach Parts Center.

Sorry for the delay. I used this with my tk41 & it worked perfectly. I don't know the diameter or head size of the 51, but if it's the same as the tk41 it should work great! Just give it a little time playin with it to let it loosen up. It will be tight at first.
