Got the job done

spring applies pressure on wood before blowing out and splintering the backside of the cutout. wood dust also clogs the cutting teeth.

Le facilita hacer el trabajo

Used to install light on my trailer. Cut 12 holes and it the saw is still like new.

Very nice hole saw. Really tough. Ive cut thru plywood in a few seconds, but it does leave a ratty entrance and exit. Thats OK for roughing in plumbing or electrical work, NOT for veneer work!! This will not cut thru a 2x4 without stopping to remove the plug from the cutter a couple of times. Cuts Aluminum like butter. I use a cutting fluid made for just aluminum. I have cut 3 holes in 1/4 steel plate with no problems. Get your RPM way down for steel. Around 350 to 440rs. Again, I used a sulfur-based cutting oil for Ferris work. The hole saw is as sharp as day one.

2 of the 3 broke before I cut 4 holes. Finished with standard drill bit.

Does as its advertised. No regrets buying it. Cuts through 1/4 inch aluminum like its nothing.

I havent used these yet but they appear to be a quality product. I will repost when I have cut the first hole.

Teeth stay sharp, bell doesn’t flex, this works great with a drill press.

Got the job done 8 holes in 3/8 steel plate
