5Pcs 16-30mm 5/8-Inch to 1-3/16 Inch HSS Hole Saw Cutter, Drill Bits Set Heavy Duty Tool Kit for Stainless Steel, Aluminum Alloy, Plastic and Wood

VERY sharp! Cut through my 1/16” aluminum plate with ease and left a clean hole. The spring made the plug removal easy. Price is excellent for the quality and sharpness.

Good quality for the DIY guy

I have a collection of older hole saws that became dull and, while sufficient for wood, didn't do the job for sheet aluminum. These are wonderful for softer metal like aluminum and cut clean holes if you take the proper care for the guide hole. The teeth are sharp and strong, cutting a clean hole quickly with the proper lubricant (I use WD40 rather than any special cutting fluid - I'm cheap!). Can't speak to longevity but, with proper cleaning and oiling after use, they seem to retain their sharpness so I expect them to remain useful for some time to come.

I needed to do a one time cut through some pretty heavy metal. It made the cut I needed. If you need this for your work I don't think I would recommend these.

Size labels were smeared and illegible. These are only good for very thin material. No instructions included.

This was great. As a person who dislikes to wait for someone to do it for them... this find was just what I needed to get things done myself. Shipped fast, great quality, priced nicely, offered a few different sizes to work with. It went through metal steel door with ease, so durability was spot on. Super easy to use with your personal hand tools drills.

Great hole saws for sheet metal.

was fine at the beginning, doing what supposed to do, but today a drill bit broke working with Plastic grass and MDF. How a metalic drill bit could be broken by MDF?

These are sharp drills and work great on thin plastic & metal. For thicker material be sure to clean the cutter frequently. Best when material is clamped in a drill press. Broke the teeth on one when it jammed and twisted using a hand drill.
