Needed to increase the size of the hole for my deadbolt and this bit did the job!

Works well in plastic, however, the large shank size makes it hard to fit most standard chuck sizes.

This is a nice "little" step bit, ranging from .25" to 2" (I said little, right?). I found that it handles softer materials such as plastic, aluminum, wood, is no challenge for this bit, but harder steel is a challenge. Additionally, understand that these bits are not intended for really thick material, and the steps on this bit are about 3mm apart. I wouldn't suggest going beyond about 2-2.5mm thickness on your material, or you will end up with the incorrect hole size. A step bit of this size would be best used in a drill press. It's a great tool, just understand what it can, and cannot do.

This is a nice step drill to have in your bin of tools most step drills available at your local stores are not available in this size. Bigger step drill is great now you don’t have to elongate the hole with the Dremel or carbide bit… again great tool to have great price

I bought this for adding bulk heads to plastic tanks. This thing is amazing. It's much larger than anything i could find at the major retailers. Caution: watch the hands. When you put it on don't have your hands within reach. When this thing spins it will hurt you. Does a great job and good quality. Love it.

Was trying to drill through light sheet metal and this thing made no progress. Got out one of my old ones that were not that big and drilled out easily. This is poor quality so don’t bother to buy

Pros:• Versatile Sizing: With 12 different step sizes ranging from 1/4" to 2-3/8", this bit is incredibly versatile for a wide range of applications, from wood to metal.• Clean and Smooth Cuts: The dual spiral flute design ensures efficient debris removal and provides clean, smooth holes without jagged edges.• Durable and Heavy-Duty: Built to handle various materials including aluminum, plastic, wood, and thin metal sheets up to 3mm thick, making it suitable for multiple projects.• Easy to Identify: The laser-engraved size markings remain visible during use, making it easy to select the right step size mid-project.Cons:• Limited Performance on Thick or Hard Materials: While it works well on softer materials, this bit struggles with thicker or harder metals like stainless steel.• Shank Size: The large 1/2" tri-flat shank may not fit smaller drills, limiting its compatibility with standard home tools.Item Summary:The 1/4 to 2-3/8 Inch HSS Step Drill Bit is a robust tool designed for versatile applications. Its wide range of sizes makes it ideal for various materials, from wood and plastic to thin metal sheets. The dual spiral flute design allows for clean, precise cuts, while the laser-engraved size markings add convenience. However, it's best suited for softer materials and thinner metals, as it may struggle with harder or thicker materials. Additionally, the large shank size may not fit all drills, so it's important to ensure compatibility.Final Thoughts:This step drill bit offers a strong balance of versatility and precision, making it a valuable addition to any toolkit. It’s especially useful for those working with softer materials or needing multiple hole sizes without switching bits frequently. While it may have limitations on thicker or harder metals, its performance on aluminum, plastic, and wood is impressive. Overall, it’s a great option for both DIY enthusiasts and professionals, but ensure you have the right drill for the large shank size.Amazon Vine Program:This is a review of a product received for free via the Amazon Vine Program.
