Built for aggressive grinding on hard metals, this 4-1/2" T29 ceramic flap disc uses premium ceramic grain that continually fractures to expose sharp new cutting edges during use. That self-sharpening action helps ceramic cut fast, stay productive under pressure, and run cooler during demanding stock removal, weld cleanup, blending, and surface preparation.
The 15° T29 angled face is designed to ergonomically approach flat work surfaces, making it the preferred flap-disc profile for grinding down bead welds, blending welds, and removing stock across flat steel and stainless surfaces. Compared with zirconia, ceramic is the step-up choice when you need more aggressive cutting performance on harder metals and sustained grinding under heavier pressure.
Available in 36 through 120 grit, this disc gives fabricators a full working range from heavy stock removal through blending and finish refinement. The ceramic abrasive is supported by X-weight polycotton cloth and a fiberglass backing plate for the durability and control needed in demanding fabrication, maintenance, and repair work.

Product Features
Premium ceramic grain for aggressive stock removal on hard metals
Self-sharpening grain fractures during use to continually expose fresh cutting edges
Designed for strong cutting performance under heavier grinding pressure
Ceramic construction helps reduce heat buildup during demanding grinding
T29 angled face ergonomically approaches flat work surfaces
Preferred profile for grinding down bead welds and blending flat metal surfaces
Overlapping flap construction combines grinding, blending, and surface refinement
X-weight polycotton cloth backing provides strong abrasive support
Always verify that the grinder is approved for the disc diameter and mounting style, that the proper guard and mounting hardware are installed, and that the grinder's operating speed does not exceed the flap disc's 13,300 RPM maximum.
Safety Tips
Inspect the flap disc before use and do not use a damaged disc.
Never exceed the maximum rated speed of 13,300 RPM.
Use the proper grinder guard and compatible mounting hardware.

Frequently Asked Questions
Ceramic grain is designed for aggressive grinding on hard metals. It continually fractures during use to expose fresh cutting edges, helping maintain strong cutting performance under heavier pressure.
Both are premium self-sharpening abrasives. Ceramic is typically chosen for faster cutting and sustained performance on harder metals or higher-pressure work, while zirconia remains a durable choice for general and heavy metal grinding.
T29 flap discs have an angled face that ergonomically approaches flat surfaces, making them the preferred choice for grinding down bead welds, blending welds, and controlled stock removal across flat material.
A T29 flap disc has an angled face and is generally preferred for flat grinding applications such as bead welds. A T27 flap disc has a flat face and is commonly preferred for shaped and non-flat surfaces such as fence posts, gates, risers, tubing, and similar fabricated components.
This ceramic flap disc is available in 36, 40, 60, 80, and 120 grit.
No. This is a regular-density ceramic flap disc.
Dry use only.
Compatible examples include the Benchmark Abrasives 4-1/2" Corded Angle Grinder, Makita GA4530, DEWALT DWE402, Bosch GWS10-45P/GWS10-45PD/GWS10-45DE, and Milwaukee 2880-20. Use the correct 7/8" centering flange, retaining hardware, and guard, and confirm the grinder speed does not exceed the disc rating.
