Hammer drills have a percussion hammering mechanism that uses two different motions to cut concrete: spinning and hammering. Carbide drill bits will withstand the force of hammer drills, but make sure your bit’s shank design will fit the chuck.

Now that you know what kinds of resources you can find using these tools, we need to address some restrictions to how you can access those resources.

Metallurgists can increase metal’s hardness through five different hardening processes, including exerting stress on the metal by hammering and rolling. Hardening the metal’s crystal structure improves the material for various applications, such as machine cutting tools, armor plating, and anti-fatigue mechanical components.

Concrete’s density, the presence of embedded materials like rebar, and the tendency of concrete to crack make it difficult to drill this material. You can use a carbide drill bit to cut concrete and rebar. The tungsten-carbide tip and the bit’s geometry give it rugged durability.

Now that you have some ideas about the extent and kinds of sources you need, it’s time to think about which search tools will find them. It might be tempting to do all of this information-gathering with a single internet search. However, you may need to use many types of sources, not all of which will be covered by your basic search engine, like Google. Keep in mind that research takes time, thought, and energy, and there will often be more than one place to search or tool to use.

Carbide drill bits are the strongest bits thanks to tungsten carbide, a chemical compound containing tungsten and carbon. These industrial drill bits are useful for metalwork, masonry, and construction projects. Learn more about the materials you can use carbide drill bits on to understand the tool’s versatility.

Finding tools provide structure for information searches. They include information about a resource’s content (like what topics are discussed) and how it is packaged (like the format). In this chapter the three main categories of finding tools that we’ll discuss are web search engines, library discovery tools, and article indexes. You’re probably already familiar with at least one of these finding tools. While all of these tools are typically accessed via the internet, they function in different ways and search different things. Some finding tools overlap in coverage (e.g., all article indexes can find journal articles, but web search engines can also find some articles), but each has its own unique features that can help you find particular types of resources. The finding tools complement each other and each is a vital piece in the information-seeking puzzle. Below is a breakdown of the different finding tools we’ll discuss in this class.

You can also use carbide drill bits on non-ferrous materials like cast iron, plastic, brass, bronze, copper, and aluminum. People use non-ferrous metals in various applications because of attributes like conductivity, corrosion resistance, lighter weights, and non-magnetic properties. Use a carbide drill bit to cut these materials with ease.

Carbide drill bits are the strongest for metal and can cut work-hardened ferrous metal, including stainless steel. Carbide metal drill bit sets are multi-purpose and can be used for creating holes of different sizes, improving efficiency in metalwork shops and other industrial settings.

Web search engines are tools that search the internet using the keywords you provide. Some popular search engines are Google, Bing, DuckDuckGo, and Yahoo.

Library discovery tools combine the traditional library catalog (showing you what a library owns) with a collection of links to many journal articles and other online resources the library subscribes to. ISU Library’s Quick Search is an example of a library discovery tool.

Article indexes and databases help you find scholarly materials such as journal articles, book chapters, and more. These tools use the keywords you provide to search through details about scholarly sources (such as topics, authors, and titles), allowing you to find targeted results. ISU Library’s list of article indexes and databases provides examples you have access to as an ISU student.

Ceramic tile is common in bathrooms, bar areas, kitchen backsplashes, mudrooms, and other spaces. If you want to drill ceramic tile to install new hardware, for instance, use a carbide drill bit. The wrong drill bit or technique can crack ceramic tile, and most drill bits can’t cut through the fire-hardened glaze. Start the hole slowly, then increase to a medium speed to avoid overheating the bit.

Carbide drill bits can cut work-hardened metals, non-ferrous materials, concrete, and ceramic tile. Invest in quality carbide drill bits for exceptional hardness and durability that make it easier to drill these challenging materials.
