Best High alumina Bauxite

NGK Spark Plug NGK DPR8EA-9 ea 1

98% pure copper core increases heat dissipation for more reliable starts and prevents spark plug from overheating.
High-grade alumina silicate ceramic insulator for superior strength and heat transfer.
Cold-rolled threads to prevent cross-threading and damage to cylinder heads.
Trivalent plating eliminates need for anti-seize and corrugated ribs prevent flashover.

Extended Lifespan – All 4-1/2’’ x 7/8’’ flap discs are made of premium alumina oxide grains, polyester flaps and multi-layered fiberglass plates, making them more durable than other flaps discs on the market.
Upgraded Performance – Our 4.5 inch flap discs use thicker abrasive clothes and more durable abrasive grains for ultimate grinding performance and user experience.
Well-Designed Pack – Coarser grit discs are more widely and frequently used, our 20 pack contains 4 different grits(40 grit, 60 grit, 80grit, 120 grit), 5 pieces of each grit..
Wide Application – 4-1/2 inch x 7/8 inch flap discs fit most angle grinders and alumina oxide grains can be applied to metal & wood grinding, polishing and finishing.
Type #27 – T27 flap discs are perfect for smoothing and blending surface.
