Migiwata Metric Titanium Coated HSS Spiral Groove Step Drill Bit Set of 3pcs 4-12/4-20/4-32mm with 1/4" Hex Shank Packed in Reusable Case for Cutting Holes in Iron Plate Aluminum Plate, etc.

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..

Step drill bit, also known as ladder drill bit or unibit, is a roughly conical bit with a stairstep profile.
Due to its design, a single bit can be used for drilling a wide range of hole sizes.
The larger-size bits have blunt tips and are used for hole enlarging.

The bits come to a point and are thus self-starting. No need to use center punch.
They are more durable and not easily broken compared with the ordinary twist drill bits.

These high-speed step drill bits feature a titanium coating so they run cool and are made out of high speed steel for a long service life.
The drill bits automatically deburr holes as you drill and the two-flute design provides faster, smoother cutting.
Whether drilling in plastic, metal or wood, these drill bits cut great every time.

Key Features:
1. Cool-running titanium coating lasts longer than uncoated bits
2. High speed steel for longer life
3. Automatically deburrs holes while drilling
4. Two-flute design gives you faster, smoother cutting
5. Quick-change 1/4 in. hex shank
