Abrasives smooth, finish, grind, or mold workpieces by repeated friction between the abrasive material and the workpiece surface area. Abrasives come in a wide range of shapes and sizes with a choice between natural or synthetic materials. Natural abrasives are comprised of organic minerals like sand, calcium carbonate, and pumice. Synthetic abrasives are made from manufactured materials like zirconia alumina, ceramic, and silicon carbide. Common types of abrasives include flap wheels, honing stones, sanding discs, and finishing discs. Choosing the right abrasive depends on the the desired finish, shape, and cut of the workpiece. Abrasives are assigned a grit size that follows national and international standards for the size of the embedded particles. Abrasives with smaller grit sizes erode surfaces faster, cut deeper, and produce a coarser finish because the particle sizes are larger. Larger grit sizes produce a smoother finish because the abrasive particles are smaller. Aluminum oxide is the most common grain of abrasive material and is used for general-purpose abrading on metal and wood. Zirconia alumina is suitable for more aggressive stock removal on metal and wood.

Cutting tools, also referred to as cutters, are tools designed to remove workpiece material—typically metal—using one or more cutting edges. They are either single-point tools, such as turning and boring tools, or multi-point tools, like end mills and drill bits. As the name suggests, single-point tools have one cutting edge, or chip-producing element. These tools are commonly used in lathes to perform planing and shaping operations. Tool bits are examples of single-point tools. Multi-point tools have more than one cutting edge. These tools are used in holemaking and milling operations.
Tool geometry and cutter material are arguably the most important features of cutting tools and should be considered based on the tool’s specific task and the material being cut. The tool’s cutting edge must be harder than the workpiece material, it should be able to reasonably withstand high temperatures, and it should have an acceptable level of wear resistance. These three factors should be considered in order to achieve maximum productivity, extended tool life, and monetary savings. High speed steel is a standard cutter material because of its relative low cost in addition to toughness and hardness factors.
Other important characteristics of cutting tools are the number and design of the tool’s flutes and whether the tool is designed for linear or rotary motion. Linear tools include broaches, while countersinks and counterbores are examples of rotary cutting tools.
