Silverline Drill Gauge 1 - 13mm (598570)

Product Information

Taper gauges are available in either analogue or digital formats, with specific models designed for slots and bores. Different width taper gauges are also available depending on the size and depth of the hole to be measured. Digital taper gauges will usually offer the highest accuracy due to it being able to display measurements to multiple levels of decimal places, as well as it eliminating chances for human error. Cost: A drill gauge can be expensive, particularly if it is of high quality. This makes it difficult for some people to afford a drill gauge. Accuracy: Drill point gauges offer a high degree of accuracy and repeatability. They are designed to precisely measure the angles of a drill bit, allowing it to be set to the exact specifications that are required. The drill size chart below contains imperial and metric drill bit diameter measurements for all number and letter gauges. Gauge

You can use the drill chart that follows this section to help convert sizes, or you can do the math yourself. Concrete – Drill gauges can also be used on concrete. Concrete is much harder to drill than other materials, so it is important to use a drill gauge to make sure the hole is the correct size. Thread pitch gauges cover a variety of thread forms and sizes including Metric 60°, Unified National (UN) 60° and British Standard Whitworth (BSW) 55°. Pitch for metric sizes is measured in mm whereas pitch for imperial sizes is measured in TPI (threads per inch). Leaf pictures range from 0.25mm up to 7mm or 4TPI to 62TPI.Everyday home repair and construction projects, hobby, marine, farming, woodworking, metal working, aircraft, arts and crafts, commercial building projects, machinery and more. Many times, we’re just trying to find out the alternative sizes available if you’re working with metric sizes (measured in millimeters) versus standard or empirical values (our familiar fractional inch variety).

Many people don’t know how to use a drill point gauge properly. Here are some tips on how to do so: Keep hands away from drill bit – always keep hands away from the drill bit while the drill is in use. Point gauges are used in fluid mechanics to measure the static pressure of a fluid. Static pressure is the force per unit area that a fluid exerts on a surface. It is measured in units of pounds per square inch (psi). Letter gauge drill sizes are used primarily in North American with A starting with the smallest size working 26 size increments to Z. Gauge Most commonly used in the US, but can still be found occasionally in the UK, these imperial measurement drill bits come in 1/64 inch increments. The fractions used are always in their simplest form, i.e. reduced as far as possible, so 2/64 becomes 1/32 for instance.Say, for example, a typical 29-piece set. In the following drill bit chart are the typical fractional sizes this kind of set would include.
