⚡ At a Glance
- • Cutting Quality: Aggressive 40 grit removal with steady, even wear on hard metals and stainless steel
- • Best for: Metalworkers, fabricators and DIY enthusiasts needing rapid stock removal and deburring
- • Not ideal for: Fine finishing or polishing tasks that require a finer grit
The 115 mm T29 flap disc uses European refined calcined and blue zirconium corundum abrasive on a reinforced fiberglass backing. Designed for angle grinders with a 22.23 mm bore, the disc meets EN 13743 and is MPA certified, with a 13,300 RPM limit.
Long-lasting, consistent grinding – thanks to European refined calcined and blue zirconium corundum abrasive
Blue zirconium corundum and refined calcined grains deliver hard-wearing abrasive performance, resisting premature glazing and maintaining cutting edges over many passes. The abrasive composition is chosen for durability on tough metals.
Longer usable life means fewer disc changes during large jobs, keeping workflow steady and reducing downtime.
Stable, safer operation – with reinforced fiberglass backing
A reinforced fiberglass backing plate absorbs vibration and resists deformation at high speeds, helping prevent smearing and maintaining disc shape under load. Certification against EN 13743 and MPA testing confirms mechanical safety at rated RPM.
Reduced vibration improves handling and comfort, making prolonged grinding sessions less fatiguing and safer.
Versatile heavy material removal – with 40 grit T29 conical flap design
The 40 grit grade delivers aggressive stock removal, while the T29 angled flaps conform to curves and contours more readily than flat discs. The 115 mm diameter and 22.23 mm bore suit standard 4.5 inch angle grinders.
Fast deburring, shaping and edge blending on stainless steel, steel and sheet metal, saving time on preparation and repair tasks.
