Jancy Engineering Inc., offers Sheet Metal cutters as an alternative to using bi-metal hole saws. Available in sizes ranging from 5/16" to 3", the products are constructed of M2 HSS. In addition to providing accuracy and rigidity in hole drilling operations, this material can also reduce the possibility of producing egg-shaped holes.
With the company’s custom arbor systems, the cutters can be used in hand-held drills or on drill presses with 3/8" or 1/2" chucks. The arbor system allows for installation and removal of the cutters without users having to worry about the cutter becoming thread locked on the arbor, says the company.
