Cutters, Annular

Shimmit Machine Tools and Equipment offers the Jetbroach range of annular cutters from Nitto Kohki Co, Japan. These cut holes up to 100 mm wide and 75 mm deep, three times faster than conventional twist drill. These replace conventional HSS twist drills with enormous, added advantages. Being a hollow, annular cutter, it reduces only 20% of the area of hole to swarf; the rest remains as a solid slug. This also means the cutting area is only 20% of the entire cross sectional area of the hole. This in turn means 40% less power consumption and almost 9 times faster drilling. Jetbroaches drill holes of any diameter in single operation and so time in drilling pilot bores is saved. Also they can do otherwise difficult operations like, bias drilling, pipe mouth, pipe drilling, over lapped drilling, etc. Standard Jetbroaches: from 18 mm to 50 mm dia, up to 50 mm depth; and 51 mm to 100 mm dia, up to 75 mm depth.
