Carbide Hole Cutter Drill Bits,LAIWEI Heavy Duty Hole Saw for Stainless Steel,Metal,Cast Iron, Copper 1/2"(12mm)

Used product for drilling holes good for job I wanted it for

This cut through a thick cast iron pipe. Will easily go through any other common metal.Great value for money. Other good brand variants cost 5-7 x more.

The cutter is very good but the Alan nut that holds the drill bit 8n place should be a screw as it would hold it tighter but all in all worth the money

I bought this for cutting hole's in 22mm chipboard flooring and it was brilliant. Super clean cut , fast too. Worked fine with a decent cordless drill.The pilot drill came out a couple of times and doesn't look as robust as the starret one's that I'm used to.Far superior to regular hole saws and worth paying the premium when accuracy, speed and longevity are important.

I’ve been using this on my makita combi drill to drill holes in 6mm thick mild steel for a bumper I’m fabricating. Works amazingly and still sharp after at least a dozen holes.The only issue is the Alan key bolt that holes the drill bit into the holesaw comes loose now and again and the drill bit falls out, but a minor issue.Great bit of kit

The media could not be loaded. Wont even cut aluminium and it’s advertised as for metal lost all tooth after one turn in soft aluminium plate

Very sharp and go through steel easily. I am pleased with this cutter, it looks like it will last a lot longer than my old ones. I use it to notch steel tubing.

very sharp and very clean per each time make the hole ( for wood working ) . I didn't use for metal yet.

SUPER

Used to make 70mm diameter holes in 2.5mm thick aluminum plate. Drilling went smoothly with perfect holes as a result.

Me resultó un buen producto....yo tenía una corona d las d color rojo y la verdad q me pareció mejor material y no se desgasta tan fácil

Habe damit 2 Löcher in einen Eisenträger gebohrt. War kein Problem, das Teil ist echt gut!

Fungerar alldeles utmärkt mkt bra att göra hål i glas med prövade på 6mm tjocklek inga problem..man ska tänka på att kyla av rikligt med vatten
