To be fair to Toolstation and Screwfix they are not engineering suppliers
Try someone like MSC who have 0.1 increment drills from about six differnt makers in jobber and stub lengths, slightly more limited in teh long and extralong series. If you want to use one of the ME suppliers then Greenwood Tools do the Dormer A002 split point ones individually.
