1 pc 100/4" WA/PA/GC/A Cup Abrasive Grinding Wheel for Carbide Steel Ceramic Deburring Polishing

Green Silicon Carbide (GC) Grinding Wheel

Material: Green silicon carbide
Feature: High hardness and brittleness
Application: Ideal for Carbide, Metal and non-metal
Grit: 46#, 60#, 80#, 100#, 120#

Green silicon carbide grinding wheels feature high hardness, sharp cutting edges, excellent self-sharpening property and good thermal conductivity. They are brittle and wear easily under heavy impact, and do not react chemically with hard brittle workpieces.

Mainly used for grinding cemented carbide tools, glass, ceramics, stone, graphite, non-ferrous metals and semiconductor materials; not suitable for grinding carbon steel and tough steels.

White Aluminum Oxide (WA) Grinding Wheel

Material: White fused alumina
Feature: Very high hardness and sharpness
Application: Ideal for high carbon steel, chilled steel, high speed steel and alloy steel; Mainly used for blade, thread, drill, gear etc.
Grit: 46#, 60#,80#, 100#, 120#

Made of high-quality white aluminum oxide, sharp cutting with good self-sharpening performance. Premium white fused alumina offers sharp cutting with minimal heat, ideal for precision grinding of hardened steel. Hard & Brittle WA Abrasive for Fine Grinding of High-Speed Steel (HSS).

Chrome Corundum (PA) Grinding Wheel

Material: Chrome corundum
Feature: High toughness
Application: Suitable for forming precision grinding of cutting tools, measuring instruments, instrument parts, threaded workpieces
Grit: 46#, 60#,80#, 100#, 120#

Mainly used for re-sharpening HSS tools (drills/mills), fine grinding of stainless steel and quenched steel. Features include sharp cutting, burn-free finish, and long wheel life.

Brown Aluminum Oxide (A) Grinding Wheel

Material: Brown Aluminum Oxide
Feature: Medium hardness, good toughness
Application: General purpose grinding of carbon steel, alloy steel, malleable cast iron, and hard bronze
Grit: 46#, 60#,80#, 100#, 120#

Brown Aluminum Oxide (A) Grinding Wheel is manufactured from high-quality brown fused alumina abrasive grains bonded with a vitrified matrix. Known for its excellent toughness and good friability, this wheel delivers consistent cutting action with minimal heat generation, making it the go-to choice for general-purpose off-hand and precision grinding.
