MICROBORE unit RANGE
FIND OUT EVERYTHING YOU NEED TO KNOW ABOUT MICROBORE'S unit RANGE
A cutting tool system must have a broad range of sizes and tool shapes to choose from so that the correct tool can be selected for a specific application. Microbore® offers more cartridges, in more sizes, in more shapes and in more carbide grades than any other manufacturer of adjustable cutting tools.
Microbore® cartridge units are axially locked into a 360° cone seat that provides metal-to-metal support. It gives maximum rigidity to the cutting edge of the tool that is necessary to obtain high accuracy, high stock removal and longer tool life.
Microbore units are available in six basic sizes: 1, 2, 3, 5, 7, and 10. Each size is available in a variety of styles with either indexable inserts or brazed carbide cutting edges.
Microbore cartridges are stamped with a combination of letters and figures which identify the size and length of the cartridge, tool style and the grade of carbide (Brazed) or size of insert.
Most standard units are available in both right and left hand cutting. For standard left hand units, prefix the order code with ‘LH’. For the left hand headed up units replace the letter ‘B’ with ‘T’.
Standard Microbore cartridges in a wide range of sizes are available in a comprehensive range of tool shapes. Microbore cartridges come with zero top rake; however cartridges having 12° top rake are available for machining aluminium and other light alloys. Microbore cartridges having non-standard dimensions, carbide grades, and tool point radiuds, are designed and manufactured to suit customer requirements.
