## Overview

BHA’s 4.5-inch Type 27 metal grinding wheels deliver heavy stock removal with extra coarse 24 grit aluminum oxide bonded in a durable fiberglass-reinforced disc. Designed for angle grinders with a 7/8-inch arbor, these precision-balanced wheels spin up to 13,300 RPM, making them ideal for weld dressing, rust removal, and surface prep on steel, stainless, and cast iron. Sold in a convenient 5-pack, they combine professional-grade durability with trusted performance favored by metalworkers and fabricators.

## Description

BHA (formerly Black Hawk Abrasives) has built professional-grade abrasives on Long Island, New York since 2015. These 4-1/2 inch metal grinding wheels are made for the shop where the grinder runs all day and the work has to keep moving. Each 5 pack contains Type 27 depressed center grinding discs measuring 4-1/2 x 1/4 x 7/8 inch, rated to 13,300 rpm. The quarter-inch thickness gives the wheel enough body to take heavy stock removal without folding under pressure, and the depressed center clears a standard guard so the operator can work the face flat or at an angle without fighting the tool. The abrasive is A24 aluminum oxide - an extra coarse 24 grit grain in a hard resinoid bond. Coarse grain pulls material fast on the first pass. The hard bond holds that grain in place long enough to finish the job rather than shedding it across the floor. Fiberglass reinforcement runs through the body of each grinding disc, adding side-load strength for the moments when the wheel catches an edge or the angle shifts mid-pass. These 4.5 grinding wheels work metal and stainless steel. Welders knock down weld crowns and dress edges before the next pass. Fabricators run them on mill scale, rust, flash, and burrs across carbon steel, stainless, and cast iron. Maintenance crews keep a stack of these grinder discs on the shelf for repair work where the surface has to come back flat. Type 27 wheels are built for grinding, not cutting. Run them on the face at roughly 0 to 15 degrees. For cut-off work on steel or stainless, BHA makes a separate line of cut-off wheels sized for the same grinders. Fits any standard 4-1/2 inch angle grinder with a 7/8 inch arbor. Inspect each wheel for damage before mounting. Always use a guard, personal protective equipment, and proper mounting procedures, as directed in ANSI safety code B7.1 and OSHA.

## Features

- 4-1/2 INCH GRINDING WHEELS, 5 PACK: Five Type 27 depressed center grinding discs measuring 4-1/2 x 1/4 x 7/8 inch. The quarter-inch thickness carries heavy stock removal, and the depressed center clears the guard on any standard 4.5-inch angle grinder.
- METAL AND STAINLESS STEEL: Grinds down welds, mill scale, rust, and burrs on carbon steel, stainless, cast iron, and other ferrous metal. Fabricators reach for these metal grinding discs on weld cleanup, edge prep ahead of welding, and work that finishes flat.
- A24 ALUMINUM OXIDE, FIBERGLASS REINFORCED: Extra coarse 24 grit aluminum oxide in a hard resinoid bond pulls material fast and holds a usable profile as the grinding wheel (4-1/2 inch) wears. Fiberglass runs through the disc for side-load strength under heavy grinding.
- PRECISION-BALANCED, RUNS TRUE: These 4-1/2 inch angle grinder discs are built flat and balanced to spin true with minimal wobble and vibration for smooth, steady, consistent results; fit any standard 4-1/2" grinder with a 7/8" arbor, rated to 13,300 RPM.
- TRUSTED BY PROS: BHA (formerly Black Hawk Abrasives) is a name welders, fabricators, and metalworkers rely on - delivering consistent cut quality and dependable performance job after job, backed by real customer support.

## Questions & Answers

**Q: With these be good to sharpen my lawn mower blades?**
A: There's a review stating the user combined these with a sharpening guide in their lawnmowing business.  If you can't find a guide for your angle grinder/blade of choice, contact a geek with a 3D printer.

**Q: do you have 3”.metal.cutoffdisk.metal.sandingdisk/for.ryobi.rigid.milwaukee/foranglegrinder?**
A: No! I use the tool for grinding mower blades only.

**Q: Is this rated at least 11,000 rpm?**
A: This page is tricky - for the 5 inch Grinding Wheel, it states Max RPM 12,200

**Q: Would this be effective for grinding concrete or mortar?**
A: They make them for concrete, or metal. They are different composition. I guess it would work on concrete, but would probably load up. Better to order the ones made for concrete.
