Ideal for jewelers and metalsmiths working with thin bezel wire or decorative sheet work, this mill produces clean, consistent corrugation across material up to 34mm wide. It must be mounted in a vise or attached to a workbench before use.\u003c\/p\u003e\u003cp\u003eThis mill includes four different pairs of corrugating rolls, ranging from very fine to coarse tooth spacing, giving you control over the corrugation pattern. Tensioning is adjusted with the large knob on top, and the mill can be disassembled if the rolls become stuck during use.\u003c\/p\u003e\u003cp\u003eBest results are achieved with 30 gauge (0.25mm \/ 0.010\") soft precious metal sheet. Thicker material such as 26 gauge (0.40mm \/ 0.016\") copper can be run through the mill, but will produce more of a surface marking effect than true corrugation. This is a simple direct-drive mill without the leverage required for hard or thick metals — attempting to run such material risks damage to the rolls or frame.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFour pairs of corrugating rolls with varying tooth spacing — very fine to coarse\u003c\/li\u003e\n\u003cli\u003eAccepts soft metal sheet up to 34mm wide\u003c\/li\u003e\n\u003cli\u003eTop-mounted tensioning knob for easy adjustment\u003c\/li\u003e\n\u003cli\u003eDisassemblable design if rolls become stuck\u003c\/li\u003e\n\u003cli\u003eMust be mounted in a vise or secured to a workbench\u003c\/li\u003e\n\u003cli\u003eDirect-drive mechanism — not suitable for hard or thick metals\u003c\/li\u003e\n\u003cli\u003eBest results with 30 gauge (0.25mm \/ 0.010\") soft precious metal sheet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall Dimensions\u003c\/th\u003e\n\u003ctd\u003e12\" tall × 3-1\/2\" × 2-1\/2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Sheet Width\u003c\/th\u003e\n\u003ctd\u003e34mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNumber of Roll Pairs\u003c\/th\u003e\n\u003ctd\u003e4 (very fine to coarse)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDrive Type\u003c\/th\u003e\n\u003ctd\u003eDirect drive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eVise or workbench mount required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eItaly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRecommended Material\u003c\/th\u003e\n\u003ctd\u003eSoft precious metal sheet, 30 gauge (0.25mm \/ 0.010\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eA smaller version of this corrugating mill is also available — see item 125.375.\u003c\/li\u003e\n\u003cli\u003eThis mill is not designed for hard metals or heavy gauges.
