For anyone who finds this, i found a solution.

Install Custom Functions plugin (so that core files remain unhacked) and add this php snippet:

/* Enter your custom functions here */ // Remove the additional information tab
function woo_remove_product_tabs( $tabs ) {
    unset( $tabs['additional_information'] );
    return $tabs;
}
add_filter( 'woocommerce_product_tabs', 'woo_remove_product_tabs', 98 );
