GSTK Upgrade Heavy Duty Carbide TCT Carbide Hole Saw Kit 10Pcs for Hard Metal, with 2*Extra Titanium Plated Pilot Center Drill and 2*L-Wrench

Works adequately. Nice clean cut with no walking. Not as durable as the one's offered by Hougen, but also not the nearly the cost of the Hougen.

EXCELLENT PRODUCT-- FIRST TASK WAS DRILLING THRU TWO PIECES OF 1/2 IN STEEL PLATE WITH AN 1.5 INCH DIAMETER SAW-- WENT THRU LIKE BUTTER AND LEFT A SMOOTH CUT- HIGHLY RECOMMEND USING CUTTING OIL TO HELP FLOAT OUT THE CHIPS GREAT VALUYE FOR MONEY-- AFTER CUT BIT APPEARED TO SHOW ZERO SIGNS OF MARKS OR DULLNESS

Good quality

I was very skeptical of the quality of these bits for the price, but they proved me wrong. I have had a very good experience with them. I have been punching hole through half inch plate and these things just eat. Awesome performance for the price. The sizing that is embossed in the side of each bit is very close to actual size drilled.

I was pleasantly surprised on the performance of these bits

So far they are decent bits. Drilled several holes and they are still holding up. I will buy again if they tear up

I finally got a chance to use my new metal hole saw bits.I’m running electrical in my new metal building and needed a tool to cut holes through the metal panels and 2”x3”metal studs.I knew they would go through the metal wall panels easily since the sheets are so thin, and they did. The hole bit cut a perfect burr free hole and the spring loaded bit ejected the blank right out.So when I got to the thick metal studs I was hoping the bits worked just as good. I couldn’t believe how easily they cut through the studs and left a perfect hole to run my wires through.These bits are worth every penny I spent.If they hold up and stay sharp I’ll have zero complaints.I would recommend them. So far a great tool!

Cuts good but will not go through hole it cut I had 1 drilling hole got in a bind and bent the shaft goes in drill
