Cut-off wheels are utilized by metal fabrication and manufacturing industries to remove excess material from workpieces.
Cutting wheels or cut-off wheels are bonded abrasive wheels. Cut-off Wheels are made of high-quality (coarse or medium) abrasives grain for general purpose cutting of stainless steel, carbon steel, aluminum, and other metals. Cut-off wheels have different applications and structures than grinding wheels.
Cut-off wheels cut small material workpieces at 90-degree angles, whereas grinding wheels grind large material workpieces at a low angle. As a result, cut-off wheels are quite thinner than grinding wheels.
A thin cut-off wheel produces less waste and provides sharp, clean, and accurate cuts. The cut-off wheel (having aluminum oxide grain with 60 and 46 grit) is suitable for cutting ferrous metals like steel and iron with minimum burring.
Metal fabrication and industrial cutting need the use of cut-off wheels. Cutting metal sheets, steel pipes, removing rust, paint, and weld spatter are other applications of cut-off wheel.
The cut-off wheel is utilized with hand-held power machines to cut through hard materials including metal alloys, ceramic tile, stone, and concrete. When it comes to widely using hand-held tools for cut-off wheels most preferable machines are an angle grinder, chop saw, or a die grinder for effective cutting.
For a clean smooth cut with less flexibility, 4 1/2 cut-off wheels are widely preferable. These 4.5-inch cut-off wheels are ideal for cutting metal sheets, manufactured steel, iron pipes, and metal stock.
Type-1, Type-27, right-angled or depressed center are the common types of cut-off wheels. Let’s know some popular cutting wheels along with their uses:
A type 1 or Type 41 is the most efficient flat cut-off wheel. It is commonly used for the general cutting of metals. Type-1 cutting wheels have a larger cutting surface and less interference with the workpiece because it doesn't have a depressed center. These wheels are utilized with angle grinders, die grinders, and chop saws (high-speed or stationary saws).
A type 27 or type 42 is a depressed center cut-off wheel. For tight or narrow cutting a depressed center provides more space but also restricts the cutting power of the wheel, especially around corners. Type 27 cut-off wheel is most suitable with the right-angle grinders.
The right angle cut-off wheel is a multi-purpose cutting wheel. These wheels are used to cut concrete, aluminum, steel, tile, stone, angle brackets, metal studs, and other general materials.
A depressed center wheel is mainly utilized for smoothing welds, notching, beveling, cutting pipe, and stone materials.
Small diameter reinforced wheels are mainly used with angle grinders to cut small metal surfaces efficiently.
A circular saw reinforced wheel is used for almost all metal deburring. They are mainly utilized by the construction industries for cutting building materials.
Cut-off wheels have an important role in enhancing the efficiency and productivity of large-scale metal fabrication industries. These wheels are designed to play a versatile role in cutting, grinding, and notching. Cut-off wheels can be customized according to the needs and applications of the fabrication industry.
