The Hyperion Mini Drill Bit Set makes all your hobby drilling convenient and a lot easy. This assorted 14 bits kit contains both Metric and Fractional-inch bits neatly lined up in a convenient plastic case. A hobbyist or DIY's tool kit is simply not complete without this kit, as it enables to drill in both Metric & Fractional-inch units, ideal tool specially when you are dealing with multi-type fasteners.
Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shape and can create different kinds of holes in many different materials. HSS bits are hard and much more resistant to heat than high-carbon steel. They can be used to drill metal, hardwood, and most other materials at greater cutting speeds than carbon-steel bits, and have largely replaced carbon steels.

Metric drill bit sizes define the diameter of the bit in terms of standard metric lengths. Standards organizations define sets of sizes that are conventionally manufactured and stocked. For example, British Standard BS 328 defines sizes from 0.2 mm to 25.0 mm.
In the U.S, fractional inch and gauge drill bit sizes are in common use. ANSI B94.11M-1979 sets size standards for jobber-length straight-shank twist drill bits from 1/64 inch through 1 inch in 1/64 inch increments. For Morse taper-shank drill bits, the standard continues in 1/64 inch increments up to 1¾ inch, then 1/32 inch increments up to 2¼ inch, 1/16 inch increments up to 3 inches, 1/8 inch increments up to 3¼ inches, and a single 1/4 inch increment to 3½ inches. One aspect of this method of sizing is that the size increment between drill bits becomes larger as bit sizes get smaller sizes: 100% for the step from 1/64th to 1/32nd, but a much smaller percentage between 1 47/64th and 1 3/4.
