3PC Step Drill Bit Set, 1/4" Hex Shank High-Speed Steel Spiral Grooved Step Drill Bit for Sheet Aluminium Metal Wood Hole Drilling, 31 Step Sizes Taper Drill bit Set for DIY Lovers

Works perfectly, very sharp

This is a great little bit. I needed a new hole in my storm door when I changed handle styles and it went right through with no problems.

I’ve used these to drill out some holes on a thicker plastic piece and they worked great. Feels durable and are great tools to have if you like DIYing stuff.

Almost work prefect to finish my job. Need more sharpping.

I keep these in an extra pocket in my tool bags for when I need to ream out a small hole. The 1/4” base is convenient as it means I can throw it in an impact instead of switching to a drill. Surprisingly they have lasted me a long time and are so cheap I don’t stress losing them! Would buy again

These aren't super heavy duty but for the price you can't go wrong. Seller refunded me well out of the return window after the largest one of these broke. I tried reordering and Amazon lost the shipment. A+ to the seller and their customer service. The bits themselves seem to work pretty well if your not too hard on them. I used them for some copper buss bars and some aluminum Diamond plate and they seemed to go through the thinner metals pretty fast. Overall I'm happy with them for the price and would purchase again.

It works perfect. Its quite heavy you need a very good powerful drill to use it. Higly recommended for sure A+++

Just what I needed to finish a job.
