Fastcut tool chart1/2/2024 ![]() Common types of grains for cutting wheels include ceramic alumina, zirconia alumina, aluminum oxide, and silicon carbide. The grains within the abrasive of a cutting wheel are the particles that perform the cutting. CUTTING WHEEL MATERIALSĬutting wheels typically contain a few different materials - primarily the grains that do the cutting, the bonds that hold the grains in place, and the fiberglass that reinforces the wheels. Type 27 cutting wheels are designed for right angle grinders. The profile of a depressed-center cutting wheel gives the operator a better view of the cut, and it provides the ability to flush-cut because the raised hub means the locking nut can be recessed. The depressed shape allows for a raised hub as well to hold the wheel securely in place. The depressed center allows for added clearance when the operator is working at a constrained angle, though it gives the wheel limited cutting ability when working around corners, profiles, or extrusions. Instead of being completely flat, a type 27 cut-off wheel, also known as a type 42 cut-off wheel, has a depressed center. TYPE 27 CUTTING WHEEL (TYPE 42 CUTTING WHEEL) Though their straight profile and the way they mount close to the guard can diminish visibility for the operator, type 1 cutting wheels are exceptionally useful in grinders, die grinders, high-speed saws, stationary saws, and chop saws. It allows for the maximum depth of a 90-degree cut at the expense of a small amount of visibility for the operator. The flat profile helps create deep 90-degree cuts into a workpiece. Because it lacks a depressed center, it provides more cutting surface and minimizes interference with the workpiece. It is typically considered the most efficient type of wheel for general all-purpose cutting. ![]() TYPE 1 CUTTING WHEEL (TYPE 41 CUTTING WHEEL)Ī type 1 cut-off wheel, also known as a type 41 cut-off wheel, is completely flat. Some common types are type 1, type 27, type 41, and type 42, where the various numbers signify the wheels' different shapes and properties. ![]() TYPES OF CUTTING WHEELSĬutting wheels come in a few different types. This guide to cutting wheels covers the differences between various types of cutting wheels and explains how to choose the right wheel for a given application. We provide everything from 1-millimeter cutting wheels to extended-diameter wheels for larger cuts. Weiler Abrasives offers several cutting wheels for different applications. Consequently, cutting wheels are often thinner than grinding wheels - though they do not have the lateral strength required for side grinding, their minimal thickness makes them better for clean, accurate cuts. Where grinding wheels use an abrasive to grind large pieces of material off a workpiece from a shallow angle, cutting wheels typically make narrow, precise cuts at 90-degree angles. What is a cutting wheel? Cutting wheels, or cut-off wheels, differ from grinding wheels in their function and structure. In metal fabrication and manufacturing operations, various tools use cutting wheels to cut material from a workpiece.
