I dont have a personal experience, but as far as I know, it is not recommended to cut quartzite without a wet saw. Quartzite is an extremely hard and dense natural stone that requires a special tool like a wet saw with a diamond blade to ensure precise and clean cuts. Other tools like a dry saw or angle grinder can cause the stone to chip, crack, or break, ruining the slab and potentially causing injury. Its always best to seek professional help or use appropriate tools and safety equipment when working with quartzite or any stone material.
