By that I mean it can be purchased with deeper throats and longer levers for punching holes farther from the edge of the can, or larger diameter, or thicker material. For producers of prototypes or small production runs this is a great tool.<o:p></o:p></p><p class=MsoNormal>Products such as <a href="http://www.sheetmetalequip.com/newequipment/tpunch.htm">http://www.sheetmetalequip.com/newequipment/tpunch.htm</a> have a dozen ‘stations’ with lots of hole sizes on a single machine, but are limited to punching flat plates (which would then be rolled). Not so cheap or versatile though amazingly useful when prototyping or manufacturing from scratch.<o:p></o:p></p><p class=MsoNormal>For large holes there is another type of tool <a href="http://www.alibaba.com/product-gs/345107446/Manual_punch_driver.html">http://www.alibaba.com/product-gs/345107446/Manual_punch_driver.html</a> that is often used to make openings in cabinets (because it can deal with thicker material).<o:p></o:p></p><p class=MsoNormal>Regards<o:p></o:p></p><p class=MsoNormal>Crispin in Waterloo<o:p></o:p></p></div></body></html>
