In this application they work just fine. I am not sure how well they work in other applications but they appear to be well made. ### ⭐⭐⭐⭐⭐ Good tool *by on Reviewed in the United States July 29, 2026* I liked it as soon as it arrived and I used it of good quality ### ⭐ Worthless step drill bits *by on Reviewed in the United States September 4, 2025* These bits are completely worthless. I would give them zero stars, if I could. They do not cut through steel at all. This was a complete waste of money. Maybe they're okay for plastic or fiberglass, but they do not work at all for steel. I say they may be okay for plastic or fiberglass because I don't know and haven't tried. I bought them to cut a 3/4 hole in an electrical box because the knockout was not on the side that I needed it. My regular drill bit set goes up to half inch. I had no trouble with my drill bits getting the hole up to half inch. I tried with a step cutters at various sizes with zero reults. Please don't waste your money on this garbage product. ## Frequently Bought Together - Aleric Step Drill Bit Set - Titanium Coated, High Speed Steel Drill Cone Bits for Sheet Metal Hole Drilling Cutting, HSS Multi Size Hole Stepped Up Unibit for DIY Lovers,3pcs - DEWALT Drill Bit Set, 14-Piece, 135 Degree Split Point, For Plastic, Wood and Metal (DWA1184) - NEIKO 10181A Step Drill Bit Set, 3 Piece, Spiral Grooved for Faster Drilling, Step Bits for Stainless Steel, Metal, Wood, Plastic, Unibit Cone Drill Bits with 31 Step Sizes Total --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/321502978-step-drill-bit-set-titanium-coated-high-speed-steel-drill](https://www.desertcart.pt/products/321502978-step-drill-bit-set-titanium-coated-high-speed-steel-drill) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-06*
