### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very useful, and great value.
  

*by S***R on Reviewed in the United States on December 15, 2020*

I've been using these a lot on 1/8" plastic and vinyl and also wood boards.  They quickly create very nice, clean, centered holes.  I mainly use the left one with the 32nds increments.  It would be nice if the fat one went up to 1", and the shortest one is redundant.  But the set would have been well worth the $4 I paid just for the left one.

    Seemingly Solid product
  

*by T***M on Reviewed in the United States on August 2, 2019*

I’ve only had this product a week but it seems to be very solid and I imagine it will last a while, will loser my durability rating if that proves not to be true. $20 seems like a fair price, more than one would expect to pay at harbor freight but less than Home Depot. would have given 5 stars for value if it came with a case.

    Good drill bits, bad punch.
  

*by K***Y on Reviewed in the United States on June 4, 2019*

Step drills are great, the punch was disappointing though. It's not very strong. I've tried it on a handful of different materials (cast iron, aluminum, stainless steel, 1095 steel, and mild steel, wood) it did okay on aluminum, but I had to press it in 7 times to get a decent mark. Even then it wasn't enough to catch a drill bit, I still had to grab an actual punch and a hammer to make a decent mark which aluminum is a pretty soft metal so you can guess how it did on steel. The mark it made on 1095 was just a surface mark that could be wiped off. Did good on the wood though, but so would a fingernail...
