What are the standard drill sizes?
What are the standard drill sizes? Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft. Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft. Range 3 (R3) is common in casing and also deployed in deep water drilling applications.
What size drill do you use for tap?
Looking at the "Tap Drill Chart" section at the bottom, they recommend an "F" drill for a 5/16"-18 fastener.

What size drill for 5 16 tap?
When we talk about the 5/16″ tap, keep in mind that there are two measurement variations; an 18 tap and a 24 tap. While the two are 5/16″ taps, they have different measurements relating to their length and thread pitch.
What size drill bit for a 10-24 tap?
The correct size drill bit for 10-24 tap is a #25 drill bit, the measurement being 5/32”. A 10-24 cap comes in two different thread counts. Thus the size of the drill bit for each one is entirely different.

How is drill size measured?
Typical drill bits have markings somewhere on the shank above the threads. It's small, but it usually has the drill-bit diameter stamped into the metal; the number is written in fractions. For example, the markings may read: 1/4-inch, 3/6-inch or 25/32.

13mm (1/2 inch) Quite simply, the larger your chuck size, the larger shank diameter it will accept. Generally, if you want to drill holes larger than 20mm in diameter or drill into materials such as metal, then consider purchasing a drill driver with a 13mm chuck, to accommodate larger bits. Previous.
How do I choose a drill?
For more refined carpentry and repair tasks, choose a drill that has the same two-speed switch and a trigger with variable speed control that lets you vary the speed from 0 rpm to the top of each range. And if you do more hole drilling than screwdriving, look for more speed — 1,000 rpm or higher — at the top end.

What angle is a center drill?
Center drills are available with two different included angles; 60 degrees is the standard for drilling centre holes (for example for subsequent centre support in the lathe ), but 90 degrees is also common and used when locating holes prior to drilling with twist drills. Center drills are made specifically for drilling lathe centers, but are often used as spotting drills because of their radial stiffness.
What is metric dimensioning?
Metric dimensioning is routinely used for drill bits of all types, although the details of BS 328 apply only to twist drill bits. For example, a set of Forstner bits may contain 10, 15, 20, 25 and 30 mm diameter cutters.

Cordless and Corded Drills
Power, mobility and weight are all considerations in choosing a drill. A cordless drill offers high mobility and a wide range of available features. Voltage ratings of 4 to 8 volts are sufficient for light-duty cordless screwdrivers, and drills with 12 to 18 volts will meet most homeowners' work needs.
Types of Drills
Some capabilities are necessary for certain tasks, while some simply make the work easier. Here are some considerations when choosing a handheld power drill:
Other Power Drill Features
A brushless motor offers high efficiency, resulting in better runtime, more power, greater durability and less maintenance. A drill with a brushless motor will also be lighter and quieter.
Drill Comfort and Design
Any tool should feel comfortable when you use it. A drill may feel great when you first pick it up, but consider what it'll feel like after a few hours of use. Think about the work you need to do, and balance the power you want against the size and weight you can comfortably handle.
More Ways to Drill or Drive
In addition to standard drills, there are other drilling and driving tools you can add to your collection:
