Durable Titanium Coated Bits —– The step drill bit is made from upgraded high speed steel characterized by well-balanced toughness, wear resistance and red hardness properties for better and faster hole -drilling performance. The titanium coating makes the drill bit more durable so that it can last for years with uncompromised quality.
Jam-Free Performance —– The dual-flute design prevents metal fillings from flying around and clears chips faster thus it can drill more smoothly without heating up.
Universal Compatibility —– The rapid strike tip drills twice as fast as the average step drills and can drill acrylic, PVC, wood, aluminum and iron sheets up to 0.2’’ in thickness.
Larger Size —– Our drill bit is bigger in size so it can drill holes with larger dimensions.
One Bit for All —– The bit comes with 12 hole sizes: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm. , saving you time and efforts to change bits, quadrupling your drilling efficiency compared to competition.
Customers say
Customers find the drill bit works well, particularly in plastic, and appreciate its quality and value for money, especially considering the size range it supports. The cutting performance receives mixed feedback – while some say it cuts through sheet metal without problems, others report it wouldn’t cut through at all. Durability is also mixed, with some saying it holds up well with daily use while others report it wears out too fast on sheet metal. The metal quality and size receive mixed reviews – while some praise the high-quality metal construction, others note it’s not steel, and while it’s great for large holes, some mention it’s not suitable for thicker materials.

Fair prive for a limited use tool – no issues – worked as expected.
Inexpensive step bit used to drill out a few holes for trailer hitch install. Unsure on longevity but worked without issue on two 1 1/8 holes I needed. Fair price and helped me get the job done. I believe the bit has more life in it and I’m sure it will get used in the future for jobs here & there. Good general use tool, would buy higher end if I used these all the time.

Decent quality tool.
Used this to make a new soap dispenser hole in our old stainless steel kitchen sink. Went right through, no issues. Seems like it’s pretty decent quality.

Works if you don’t need too many holes drilled
Worked great at first, but didn’t last as long as I would have liked. It started getting dull making it difficult to continue to use. At first it was nice and quick cutting through thin metal, but after a few holes it got slower and slower. There wasn’t a wobble to it, so that was good. I like the size variety, but when the smaller sizes start getting dull, it’s harder to use to get to the bigger sizes.

Sharp! Use it in reverse.
Omg!!! I thought this was super dull and just wouldn’t work untill I tried it in reverse! It was designed backwards for some reason, but it works super well! It’s very sharp and heavy duty! I’m glad I purchased it!
Amazon Customer –
Good price for a step bit
Used it to put holes in fire barrels and it went right through the metal.

Good everyday knife, but edge retention is lacking
Good everyday knife, but edge retention is lackingThis ZELCAN knife feels solid in the hand with decent balance and weight. Out of the box it came sharp enough for typical household tasksâopening packages, light food prep, and small DIY projects. The handle has a straightforward, no-frills design thatâs comfortable enough for short use.Where it fell short for me was the bladeâs edge retention. It dulls fairly quickly, even with light use, meaning it needs frequent honing or sharpening to keep it performing well. For someone who only uses a knife occasionally, this may not be a big issue, but if you expect it to hold an edge over time, it can be frustrating.Bottom line: A serviceable budget knife that does the job but loses sharpness faster than Iâd like. Best for casual or light use, not heavy-duty cutting.

Great addition to my tool box!
I needed this bit to install some electronics on my boat. The bit operated as expected and the holes were perfect. I searched the two big box hardware stores for this bit and both had it at 2-3 times the cost. The quality of this bit is great and it is a great value. I highly recommend.

Trailer Hitch for 2024 Crosstrek Limited
I used this bit with a Kobalt 24v cordless drill, and it did the job nicely. In prep to mount an (E-Trailer) hitch, I had to bore out two existing holes to fish mounting bolts through. Half way through the second hole, the bit seemed to get a little dull, thus the 4 star rating. You may want to use gloves in using this, as it will spit out very hot shards of metal that will melt into a synthetic moisture wicking shirt.

Lo usé para ampliar un barreno y en el segundo ya no corto, en placa de 3/16 muy mala calidad

Using it to widen holes in steel doors has held up well so far.

No perforó más de 3/4
Darren J. –
Wasnât sure with this being so large how well it would work, but in my Dewalt 20V drill, it went through metal as intended.. the drill did struggle a bit, and watch you donât break a wrist when it catches the metal, but I managed to get a hole drilled right to the largest size.. 2 3/8âNot sure I will ever have a use for this large of a hole in metal again, but this did the job for what I needed it to!

Me gustó que tuviera margen para orificios grandes, lo que no me gustó es que el filo muy fácil se amella
