Metric dimensioning is routinely used for drill bits of all types, although the details of BS 328 apply only to twist drill bits. The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. Machinists generally truncate the decimals after thousandths; for example, a 27/64" drill bit may be referred to in shop-floor speech as a "four-twenty-one drill". Standards organizations define sets of sizes that are conventionally manufactured and stocked. Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion. You can target the Engineering ToolBox by using AdWords Managed Placements.

The tools that the software provides—formulas, cell formatting with rounding, autofill, and sorting by numerical order—obviate any manual calculation and data entry. Standard metric lengths (from standards like BS 32*) define metric drill bit sizes using this system: For 0.2 to 0.98mm, sizes use N from 2 through 9: 1. Enter e-mail addresses in the fields below. Drill Size Conversion Table This table is the chart for converting and identifying various drill bit sizes. The gauge-to-diameter ratio is not defined by a formula; it is based on—but is not identical to—the Stubs Steel Wire Gauge, which originated in Britain during the 19th century. Their shorter flute length and shorter overall length compared to a standard jobber bit results in a more rigid drill bit, reducing deflection and breakage. BS 328 drill sizes are defined as shown in the drill size chart below: Number and letter gauge drill bits are still in common use in the U.S. and to a lesser extent the UK, where they have largely been supplanted by metric sizes. Center drills are made specifically for drilling lathe centers, but are often used as spotting drills because of their radial stiffness. Double Cut Carbide Burrs .
