Applications & Performance
This bundle is designed around the three jobs performed most often with an angle grinder: cutting, grinding, and finishing.
Instead of stocking separate products one at a time, you get a high-volume assortment that lets you move through the complete fabrication process with the same grinder platform.
Cut
The bundle includes 80 thin cut-off wheels for fast, controlled cuts through metal.
Use the T1 flat wheels when a traditional flat cut-off wheel configuration is preferred. The T27 depressed-center wheels provide additional mounting clearance for compatible angle grinder applications.
Common cutting applications include:
- Steel plate
- Sheet metal
- Rebar
- Pipe
- Tubing
- Angle iron
- Bar stock
- Stainless steel
- General metal fabrication
Grind
The 20 T27 grinding wheels provide the durability and thickness needed for aggressive material removal.
Common applications include:
- Grinding down heavy welds
- Removing weld buildup
- Beveling edges
- Removing excess metal
- Shaping steel
- Cleaning castings
- Heavy stock removal
- Fabrication and repair
Finish
Materials
Recommended for use on:
- Steel
- Stainless Steel
- Cast Iron
- Wrought Iron
- Titanium
- Nickel Alloys
- Other Ferrous Metals
The flap discs may also be used on selected non-ferrous and other materials when appropriate for the application.
Machine Compatibility
The grinder you need is included with this bundle.
Compatible examples include:
- Benchmark Abrasives 4-1/2" Corded Angle Grinder — INCLUDED FREE
- Compatible 4-1/2" angle grinders
- Compatible 5" angle grinders using the appropriate 7/8" wheel mounting system
The included Benchmark Abrasives 4-1/2" Angle Grinder operates at 11,000 RPM, making it an excellent platform for the cutting, grinding, and flap disc products included in this assortment when each wheel is properly mounted and rated for the machine speed.
Because this bundle includes different wheel types, always use the proper guard, flange, and mounting configuration for the specific accessory installed.
Safety Tips
- Always wear proper PPE, including safety glasses with a face shield as needed, hearing protection, respiratory protection when required, and suitable hand protection.
- Keep the grinder's safety guard installed and properly positioned at all times.
- Use the correct guard type for cutting and grinding operations.
- Inspect every wheel before installation. Never use a damaged, cracked, dropped, wet, or otherwise compromised abrasive wheel.
- Verify that each accessory's maximum RPM meets or exceeds the operating speed of the grinder.
- Disconnect the grinder from power before installing, removing, or changing accessories.
- Make sure the wheel is centered, properly seated, and securely mounted before use.
- Allow the grinder to reach full operating speed before contacting the workpiece.
- Maintain a secure two-handed grip during operation.
- Never use the side of a thin cut-off wheel for grinding.
- Use cut-off wheels only for cutting applications unless specifically rated otherwise.
- Use grinding wheels and flap discs at the proper working angle.
- Apply controlled pressure and allow the abrasive to perform the work.
- Excessive pressure increases heat, wheel wear, and the possibility of wheel damage.
- Direct sparks away from yourself, other people, flammable materials, and sensitive surfaces.
- Use all included abrasives for dry applications only.
- Read and follow all machine and abrasive-wheel safety instructions before operation.

The holiday bundle sells for $272.90, giving you $83.99 in savings.
T1 cut-off wheels have a flat profile.
T27 cut-off wheels have a depressed center that allows the mounting hardware to sit below the face of the wheel.
Having both styles lets you choose the wheel configuration that works best for the machine setup and cutting application.
A flap disc combines grinding and finishing capability. Its layered abrasive flaps provide controlled material removal while leaving a smoother surface than a traditional grinding wheel.
This bundle gives you both so you can use the right abrasive for each stage of the job.
They are particularly effective for:
- Bead welds
- Flat plate
- Welded assemblies
- Beveling
- Heavy stock removal
- General fabrication on flat surfaces
The additional abrasive provides more usable material and longer working life.
60 grit is a versatile general-purpose choice for grinding and blending.
80 grit produces a smoother result and is best for weld blending and surface refinement.
Always use the correct guard, flange, mounting hardware, and operating technique for the specific wheel type installed.
- Flap discs
- Cut-off wheels
- Grinding wheels
- Surface preparation wheels
- Stripping wheels
- Wire wheels and brushes
- Other properly sized and speed-rated accessories
