Great hole saw set!
Great product. Durable construction and reasonable price. Multiple sizes. Nice and sharp. Self ejecting spring is super nice feature. Also nice that it comes with a great little cass to keep everything organized and together. Perfect set for most jobs. Highly recommend

Quality cutters at an affordable price
Hole sizes are accurate and the carbide has no problem chewing through metal, wood, plastic, or anything else you put in front of it. A drill press is definitely recommended for the larger diameters.

Worth the money! Great hole saw kit.
Genuinely a great set and super sharp. Cut though 1/4inch stainless in less than a minute and wood like it’s nothing.

Very good quality
I bought this to cut mainly through die-cast aluminium boxes. No problem! A friend of mine that has worked with industrial scale cutting machines thought highly of them too.

This is not a 10 piece hole saw set, it is an 8 piece hole saw set with 2 spare pilot drill bits.
Very misleading description that does not match the photo. It is not a 10 piece hole saw set, it is an 8 piece set with 2 spare pilot drill bits, yet the matching 4 piece set is 4 pieces with 2 spare pilot drill bits.

Relación calidad precio buena
El corte en metal de 5/8” es excelente refrigerando constantemente, los cortes son rapidísimos con los diferentes ángulos de afilado que tienen las puntas de tungsteno.
