“I was advised to get this tool as I had to enlarge some holes in a steel bulkhead from about 30mm up to 50mm. Normally i would have chain drilled and filled round with a half round file. This tool makes a mockery of that idea. In less than 2 minutes I had 2 accurate and perfectly round holes and no deformation. the tool is simple to use and is bound to come in useful for other projects. 100% recommended.”
