Tutorials on cutting metal

Are you curious about precisely how metal cutting with circular saws works? Aren't you just a little curious? Do you consider it a lot? Would you like to understand more than just the basic facts? Such things as trivia and other intriguing bits of info? You have come to the right place because every so often we update this website with various info regarding metal cutting saws. All you have to do is click a couple of links and start reading.

Cold saw(ing) machines are circular saws that are used in many metal cutting operations. The saw blades used are quite large in diameter and operate at low rotational speeds, and linear feeds. There are three common types of blades used in circular saws; solid-tooth, segmental tooth, and the carbide inserted-tooth. The circular saw is typically fed into the workpiece horizontally, and as the saw advances into the material, it severs the material by producing narrow slots. The material is usually held in place during the cutting operation by means of a vise. The chips produced by cutting are carried away from the material by both the teeth of the blade as well as the coolant or other cutting fluid used. I have used it with the included blade and was able to make some great quality cuts through 1/8" steel diamond plate, 3/16" sheet, and 3/8" flat stock with ease. One huge advantage that these types of saws have over abrasives is that the work piece is cool to the touch immediately after it has been cut, and there is no burr on the metal, which saves time and frustration. The kit includes the saw, two 5.0 Amp Hour batteries, a charger, and the case. The 5.0 batteries are a huge plus for this type of saw because of how much power it eats through, but I have been able to get quite a few cuts out of each battery, and by the time I had ran one battery out, the other is done charging so it works out perfectly. The case and charger are fairly self-explanatory, both are the same as any other that DeWALT sells, very high quality. Another great feature of the saw is the visibility, with the LED light and the clear plastic viewing window, it is very easy to see what exactly it is that you are cutting.

^ John O. Curtis, "The Introduction of the Circular Saw in the Early 19th Century". Bulletin of the Association for Preservation Technology Vol. 5, No. 2 (1973), pp. 162 189; also Inventors website and Wood News The circular saw was invented around the end of the 18th century as a rip-saw to convert logs into lumber in sawmills and various claims have been made as to who invented the circular saw. Before the design was invented logs were sawn by hand using a pit saw or using powered saws in a sawmill using an up-and-down saw with a reciprocating motion. The rotary nature of the circular saw requires more power to operate but cuts faster because the teeth are in constant motion. The sound of the circular saw is different from the sound of an up-and-down saw and earned it the nickname buzz-saw. Walter Taylor of Southampton had the blockmaking contract for Portsmouth Dockyard. In about 1762 he built a saw mill where he roughed out the blocks. This was replaced by another mill in 1781. Descriptions of his machinery there in the 1790s show that he had circular saws. Taylor patented two other improvements to blockmaking but not the circular saw.[4] This suggests either that he did not invent it or that he published his invention without patenting it (which would mean it was no longer patentable).

First things first, if you're going to cut any sort of metal using a jigsaw you need to make sure you're using the correct blade. This isn't hard to do and we've produced a guide to choosing the correct type of jigsaw blade for the tasks you're undertaking.

I have found that using wax or thinners or oils or cutting fluids just creates a clean up situation before you can weld...try using a mixture of joy soap and water if you feel you must use anything at all...We use 7 1/4 in carbide wood blades and no lubes for alum up to 3/8 1/2 inch thick...cut slow so the blades have a chance to shed the chips when cutting the thick stuff..

There are a few different types of saws that will cut through metal. We will probably all be familiar enough with the good old hacksaw and indeed the junior hacksaw. We would recommend that everyone should have one each of these in their tool bag, along with a spare set of blades for each one.

This would probably be my least favorite choice when it comes to a metal cutting saw. It is basically just a hacksaw on steroids for want of a better description. Don't get me wrong these are high quality saws, but when used on metal they are a pretty rough weapon of choice.

i had to cut aluminum production style for interstate signways. we used worm drive saws with a non ferrous metal cutting blade. lube it with aluma-cut (the tap magic stuff for aluminum) or nozzle gel. you can also use a spiral down cut router bit in a router and achieve the same results. the woodworking blades try to remove TOO much material with each tooth passing through the work and heat up too much gumming the blade and also ruining the blade. the saw will also have a real bad habit of trying to kick out of the cut. the rake and chip set on the teeth is ALOT different than that of a wood cutting blade

Click here to read our guide to why pendulum action in a jigsaw is so important. However, Bosch have re-imagined this for the GST25 M due to the type of cuts it's designed to perform. It only has 2 stages of pendulum action; on or off. This insures you'll always have the option to work fast and with great control while you cut as the pendulum action has been mechanically optimised for metal. The DeWalt DCS373L2 Kit will feature one DCS373 Metal Cutting Circular Saw, two 20 Volt MAX* Lithium Ion 3.0 Ah Fuel Gauge battery packs, one fast charger, one 5 1/2-inch carbide tipped metal cutting blade and a kit box. The kit is expected to retail for approximately $359 and will be available in July 2012. The bare model will retail for around $199 and should hit stores in April 2012. Both tools will come with a three-year limited warranty, one-year free service contract and 90-day money-back guarantee.  After conducting extensive field research, we found there was a demand for a powerful circular saw that could cleanly cut a variety of metal construction materials. Our new cordless metal saw offers the speed and portability contractors need when making difficult cuts on the job site.

Yes you can, I agree with all of the above. But it throws a lot of sharp chips and sparks. So beware. There is a carbon saw that is designed for metal...wears as it cuts. will last 12 feet in 14ga sheet metal. When you are in need of making very delicate cuts, such as curves, a jigsaw is an incredibly handy tool to accomplish this task. Friction is the main issue that is caused when you are working with stainless steel, and stainless heats up very quickly and when that happens the heat is transfered to the blade of the tool, which can then cause it to soften and break or even dull the tool. The first thing you will want to do is to find a fine toothed carbide steel blade that will not react to this heat too quickly. The next thing you will want to do is to make sure that you run the blade of the jigsaw at a slower pace, so that you can minimize this type of friction heating up. Do not force the blade and let it do the work for you so that you can keep from adding any extra friction to the metal and the blade. e& GOXAWEE Tool e& is the source for hard-to-find mini tools for crafts and hobbies.

You'll need different blades for different kinds of metal. You should be able to use a carbide-tipped abrasive cutoff wheel for non-ferrous metals like brass, aluminum, copper or lead. Carbide-tipped blades last up to 10 times longer than regular steel ones. The pitch and design of the blade you choose will also vary depending on the thickness of the metal in question. In general, you'll want a higher tooth count for thinner metals and a lower tooth count for thicker ones. The packaging of the blade should specify what material and thickness the blade is appropriate for, and if you have any questions, you can always contact the manufacturer.
