Yakamoz 6PCS High Speed Steel HSS Drill Bit Hole Saw Set Stainless Steel Metal Alloy Kit 16mm 18.5mm 20mm 25mm 30mm 32mm

Used for 1st fix plumbing in new builds where I have to drill through metal stud work. In a combi drill these make a hole in less than 3 seconds with no snagging or rips, perfect clean hole every time. The spring on the pilot bit even self ejects the cut metal afterwards, absolute bargain

Arrived very well packaged and are VERY sharp, perfect for the job I bought them for (drilling a tap hole in a new granite sink unit) I have since used them for many other jobs around the house. Very good quality that will last a long time.

These hole cutters only drill thro' material up to 8mm thick. Otherwise decent cutter.

although at first sight this product was good quality, but since i have retured to work and tried them out i was disapointed. The first one i tried was the 32 mm with a hand drill but even on it's slowest speed i thought it was too fast so i was using stop/ start method so as not to overheat the bit, but it jammed and tore off most of the teeth. I then tried the small 16mm bit in a pedestal drill on a slower speed of 120 rpm but it tore off all of the teeth.As there was no instructions on what rpm was needed for these hole saws it was trial and error. However i did try another bit the 30mm on a higher speed of 300 rpm with a very slow feed and it seemed to be ok but is this the correct way. As i still need holesaws for my job iwould need the two damaged ones replaced if thats possible, if not i shall return all six and try to find other alternative. I will wait for a responce before i decide.Mr Leslie Campbell

Went through sheet metal like it wasn't there! Wouldn't recommend for thicker materials as working depth is limited

Excellent value used several times on steel and brass they are still sharp and accurate.

Amazing product, done the task of drilling through my metal shed perfectly and was easy to use, would highly recommend after purchasing a similar product that just scratched the surface this tore through with ease

The smaller 2, the 16mm & 20mm cut 0.5mm thick stainless steel no problem. The rest just overheated and case hardened the 0.5mm stainless steel. Really disappointed.
