Milwaukee metal circular saw blades were specifically designed to exceed the expectations of contractors for blade life, cut quality, and speed in the most demanding metal cutting applications — without a lubricant. A hand-tensioned, hardened alloy steel body extends blade life and delivers the highest quality cuts available. Carbide tipped teeth with Alternate Top Bevel grind shear through metal leaving burr-free, cool-to-touch cuts. Designed for use with the M18 Cordless 5-3/8" Metal Saw, these blades feature a thin kerf that reduces the amount of drag and resistance while cutting, resulting in more cuts per charge.

Rated 5 out of 5 by from Better than anything in a chop saw!! We use almost anything for cutting metal from torches to tin snips. Other than the metal circular saw that we have been using for years which has been god sent for grating and other thin plate metal, this is the best. The electricians on site were using it in there chop saw to cut various material from aluminum to galvanized unistrut then we used it for regular mild steel 2"x2"x1/4" angle to 3/8" angle and 1/4" kickplate

Rated 5 out of 5 by from best deal bought many different brands more and less expensive and by far these are the best all around blade i've found. i use it in my milwaukee hand held saw, do a lot of fabricating cutting tubing and angle iron. these cut and last very well.

Rated 4 out of 5 by from teeth seem to dull fast - can you help? I've been cutting 3/16" wall square tubing with the 5-3/8" cordless Milwaukee saw and the 5-3/8" 30 teeth metal saw blade and the teeth seem to dull quite quickly. I followed the instructions directing to only have the bottom of the blade extend no more than 1/4" below the bottom of the steel being cut, but must be doing something wrong to have the blades dull so quickly. Do you have tips for extending the life of the blade? Can the teeth of the blade be sharpened? thanks.

Rated 5 out of 5 by from Cuts EVERYTHING- Milwaukee 48-40-4070 Bought this as a replacement for an identical one I finally wore out. I've cut everything with this blade. Steel, copper, aluminum, nail embedded wood, pvc and more. Nothing stops it and it lasts more than twice as long as any other blade I've ever used. This is add close to being perfect as a blade could be.

Rated 5 out of 5 by from The best choice I have had my saw for over a year and use it daily in construction. I cut all thread rod and steel pipe with it on a daily basis and after using the Milwaukee blades plus another brands blades, Milwaukee is the winner hands down. Tools plus delivered on time and with no problems at all. Thank you.
