## Description

Full description not available

## Features

- Conical bit with a stairstep profile to be used for drilling 19 hole sizes ranging from 4-32mm, to replace 19 individual drill bits. Self-starting, no need of center punch.
- Made of high quality HSS (high-speed steel) 4241 and coated with Titanium for prolonged life.
- Commonly used on sheet metal and in general construction. One drill bit can drill the entire range of holes necessary on a countertop, speeding up installation of fixtures.
- Ideal for use in electrical work where thin steel, aluminum or plastic boxes and chassis are encountered. The short length of the unibit and ability to vary the diameter of the finished hole is an advantage in chassis or front panel work. The finished hole can often be made quite smooth and burr-free, especially in plastic.
- Automatically deburrs holes left by other bits, as the sharp increase to the next step size allows the cutting edge to scrape burrs off the entry surface of the workpiece. Save you time and effort.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Randomly picked Step Drill Bit.
  

*by M***Y on Reviewed in the United States on November 11, 2022*

I randomly chose these since I wasn't going to shell out money for a known good brand for a small project. I used the largest of the the bits to create holes in a 55 gallon steel drum. Worked perfectly. I only needed 8 holes for the project, so I wasn't expecting much wear on the bit. Looking with a magnifying glass showed a near mint bit. I was impressed for the price and being unfamiliar with the brand. 11/10. Will look for this manufacturer for future project bits.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I use this on aluminum which is overkill
  

*by P***M on Reviewed in the United States on July 27, 2022*

I'm a commercial glazier and drill holes into metal quite often. I don't use step bits often but when I do it's almost always into aluminum and most likely 1/4"-3/8" thick. I find this to size up holes for fasteners much faster than your typical proper way of upsizing metal holes with typical drill bits.This is definitely overkill as I do not need a cobalt m35 bit for aluminum but its holding up really well after over 200 holes. It's staying sharp. If you're consistently drilling holes non stop then I recommend you find yourself a way to keep this step bit or any bit cool if you're drilling aluminum. When it gets hot the shavings will stick onto the drilling edges.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Working great.

Never knew how much I would use them till they arrived.
