Product Specification
4-1/2" X .040” X 7/8" T1 PREMIUM THIN CUT-OFF WHEEL - 2000 PIECES
Built for fabrication shops, manufacturing operations, maintenance departments, and other high-volume metalworking environments, these 4-1/2" x .040" x 7/8" T1 Premium Thin Cut-Off Wheels deliver fast, clean cutting with minimal resistance. The ultra-thin .040" profile removes less material during the cut, helping increase cutting speed while reducing workpiece waste, heat buildup, burr formation, sparks, vibration, and operator effort.
Premium aluminum oxide abrasive delivers dependable cutting performance across steel, stainless steel, cast iron, and other ferrous metals. Highly refined ingredients help prevent contamination when cutting stainless steel, while internal high-tensile-strength fiberglass reinforcement provides the strength and stability required for demanding high-speed cutting applications.
The fast, cool-cutting action allows the wheel to work efficiently with minimal pressure while helping reduce the heat-affected zone around the cut. This bulk package contains 2,000 cut-off wheels, making it an excellent choice for production environments and high-consumption shops that want to maintain inventory while taking advantage of bulk pricing.

Features
-
Ultra-Thin .040" Profile: Creates a narrow kerf for fast cutting with less material loss and reduced cutting resistance.
-
Premium Aluminum Oxide Grain: Provides dependable cutting performance on steel, stainless steel, cast iron, and other ferrous metals.
-
Fast, Cool Cutting: Designed to cut efficiently with minimal pressure while limiting excessive heat buildup at the workpiece.
-
Reduced Heat-Affected Zone: Thin-wheel construction helps minimize transferred heat, reducing discoloration and burr formation around the cut.
-
High-Strength Fiberglass Reinforcement: Internally reinforced with high-tensile-strength fiberglass for stability during high-speed cutting.
-
Stainless Steel Compatible: Highly refined ingredients are formulated to cut stainless steel without introducing unwanted contamination.
-
Less Cutting Resistance: Thin construction helps reduce vibration, sparks, dust, workpiece waste, and operator effort compared with thicker cutting wheels.
-
Bulk Shop Packaging: 2,000-piece quantity is designed for fabrication shops, manufacturers, maintenance operations, and other high-consumption users.
Applications & Performance
The .040" ultra-thin profile minimizes the amount of material removed during each cut, allowing the wheel to move through metal quickly while producing a narrow cutting path. Reduced cutting resistance also means less pressure is required from the operator, helping improve control and overall cutting efficiency.
These wheels are well suited for:
- Cutting steel plate and sheet
- Cutting stainless steel
- Cutting tubing and pipe
- Cutting angle iron
- Cutting bar stock and rod
- Cutting structural steel
- Trimming fabricated components
- General fabrication
- Maintenance and repair work
- Production metal cutting
Materials
Recommended materials include:
- Carbon steel

Machine Compatibility
Designed for compatible 4-1/2" angle grinders that accept a 7/8" arbor Type 1 cut-off wheel and are equipped with the proper cut-off guard, flanges, and mounting hardware.
Compatible examples include:
-
Benchmark Abrasives BMT-AGBC4570 4-1/2" Angle Grinder (11,000 RPM)
- Makita® 9557PB / 9557PBX1
- DEWALT® DWE402
-
Bosch® GWS10-45 (11,500 RPM)
-
Metabo® WEPBA 17-125 Quick RT DS (10,000 RPM, North American version)
Use the proper Type 1 cut-off guard and approved mounting hardware for the machine. Always verify wheel diameter, arbor size, maximum RPM, flange setup, and guard configuration before operation.
Safety Tips
- Never exceed the wheel's maximum rated speed of 13,300 RPM.
- Use only on machines designed for Type 1 cut-off wheels and the specified wheel diameter.
- Always use the correct cut-off wheel guard and keep all machine guards securely installed.
- Inspect every wheel before use. Do not use a wheel that is cracked, chipped, dropped, damaged, or otherwise compromised.
- Verify that the wheel is properly mounted and secured before starting the grinder.
- Allow the grinder to reach full operating speed before contacting the workpiece.
- Use the wheel only for straight cutting. Do not grind with the side of a thin cut-off wheel or apply excessive side pressure.
- Let the abrasive perform the cutting. Excessive pressure can increase heat, reduce wheel life, and place unnecessary stress on the wheel.
- Secure the workpiece before cutting and position it so the cut does not pinch or bind the wheel.
- Always wear appropriate PPE, including safety glasses and a face shield, hearing protection, respiratory protection when required, gloves, and other protection appropriate for the application.
- Keep sparks directed away from people, combustible materials, hoses, cords, and other hazards.
