<b>[Product Information]</b><br>
<ul>
<li>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.</li>
<li>Made of high quality HSS (high-speed steel) 4241 and coated with Titanium for prolonged life.</li>
<li>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.</li>
<li>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.</li>
<li>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.</li>
</ul>
