Silverline Drill Gauge 1 - 13mm (598570)

Product Information

There are two main aspects that you need to consider when gauging a drill bit – the size and the type. The size of the drill bit is going to be determined by the size of the hole that you need to create. The type of drill bit is going to be determined by the material that you’re drilling through. Step 2: Make sure the drill point gauge is in the right position. It should be parallel to the surface of the drill bit. 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. 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. Thread pitch gauges are relatively inexpensive tools, and they are essential for anyone who works with screws on a regular basis.

Step 4: Once the drill point gauge is correctly positioned, make sure the needle is pointing to the correct angle for the drill point. If you’re curious what size drill bit you’ll need for a particular screw size (for pre-drilling pilot holes), use the following drill bit size chart: Accuracy: A drill gauge is not as accurate as calipers or micrometers, which are used to measure the diameter of drill bits and other cutting tools. A drill gauge may not accurately measure the diameter of drill bits or other cutting tools if the tool is not sharpened properly. Then, rotate the gauge until the line on the side ofthe hole lines up with either 0° (for a 118° angle) or 45° (for a 135° angle). Finally, tighten downthe vise to hold everything in place and removethe gauge fromthe vise. When you reach your desired depth, stop drilling and remove the bit from your workpiece. What is a Drill Point Gauge Used For?If you need drill bit sizes that are larger than 1″, you can often use a spade bit for wood and other soft materials. Maintenance: Regular maintenance is also recommended to ensure that the drill gauge is in good condition and is providing accurate readings. A drill point gauge is a tool used to measure the angle of a drill bit. It is important to use the correct size and type of drill bit for the material being drilled, and the correct angle helps to ensure that the bit will not slip or wander while drilling. The most common angles are 118° and 135°, but other sizes are also available. Metal – Drill gauges are also quite useful on metal. Metal is much harder to drill than wood, so it is important to ensure the hole is the correct size for the job. A drill gauge can help with this. Calibration: The gauge should be calibrated at least once a year to ensure that it is providing accurate readings.

The following drill chart covers the smallest standard drill diameter size of strong>1/64 to 21/32 and gives you the equivalent sizes in both decimal inches and millimeters . Diam. Welding gauges come in a plethora of shapes and sizes which can, at first, seem daunting. The key criteria to determine which gauge is suitable is the size of the weld, the dimension which need measuring and the accuracy to which the measurements need to be to. Welding gauges are available with either analogue or digital output and are also supplied as sets containing various types of welding gauge including fillet welding gauges, pipe welding gauges and standard welding gauges as well as micrometers, inspection mirrors, magnifiers and rules. Thankfully, we can narrow it down a a lot to some standard sized holes for bolts and screws as well as for bits. A drill bit size hole card can be very helpful for this. A simple plastic drill chart sheet with perfect round holes and markings on it lets you do a couple of things. Step 5: Finally, carefully remove the drill point gauge from the drill bit and use the drill bit to commence drilling.To make things just a little more complicated, not all drill bit sizes are in North American fractional measurements. Storage: When not in use, the drill gauge should be stored in a clean, dry place that is free from dust and moisture. Conclusion

Best of all, they’re pretty inexpensive and will be something to have as part of your DIY toolbox for many years to come. Drill Size Charts:
