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

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.

I tried these for cutting coins and they work great!

Excelente producto y rápida entrega

With a little wax these saw blades work well.

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.

Second order of these blades, quality looks better than the first 7

Never had to do work this fine before, so I bought a jeweler's saw and these blades. Have cut numerous pieces and I'm still on the first blade. If my lack of experience and two left hands can get it done with these, they're good stuff. Would recommend.

These slice well through metal. Much, much better than the cheap alternatives. Great value for money!
