Pike Jeweler's Saw Blades #3/0 144 Pack

These blades just slide through copper (with blade lubricated). I had 1 break but the copper had pinched the blade very tight when it happened. They come very neatly and securely shipped. My package was double sealed. I belive the double seal is to prevent moisture and thats a plus. Untill i find something better these are the only percing blades im going to buy. They do indeed come with the amount advertised. [::UPDATE::] These blades have held up fantastic when cutting copper. I have yet to cut other metals with them but ive managed to cut several hundred jump rings on 1 blade. I use one side of the plastic inner linner to hold broken blades.

These blades, size #3/0, cut beautifully. If you look at blade size charts available online, they are recommended for soft sheet metal such as silver or soft brass sheet, thickness 0.0250". I am cutting half-hard brass of the same thickness, and have found it better to use one size larger- #2/0 - for this harder material.All due care in handling is required, as the blades are very slender, and as they are made of hardened steel, are quite fragile if they are given side loads or if they get hung up in the cut you are making on the work piece. There is a reason they are sold in packs of 144. When you install these in the jeweler's saw, be sure to gauge which is the cutting edge and which is the smooth back, and also in which direction the teeth are intended to cut. You can generally tell this with light pressure from your fingers.Tip 1: Using some blade lubricating wax, such as BurLife, will make cutting easier and extend the life of the blades.Tip 2: if you break one near to one end, you can re-install the longer remainder in the saw and continue cutting.

A mi hermano le funcionan súper bien en su trabajo como joyero

With a little wax these saw blades work well.

I tried these for cutting coins and they work great!

These saw blades are awesome, the same saw blades my dad use for 30 years making jewelry. I use them now for making jewelry of my own, just not of gold. They cut through anything and they do it quickly you just have to be careful with a blade, which should be obvious due to the size.

Much easier to use than deep throated saw. Great for small items easy to control

These little blades are superb. If you don't know which blades to buy and you're just looking for the best blade for general use, the #3 blade size (these blades) are the one you want. By "general use," I'm not implying that this is a mediocre blade, rather, just saying that this is the middle of the road SIZE that handles most things. The quality is excellent, and it's probably one of the better overall values out there.
