The ACCUPRO A-6100089R is a solid carbide micro drill bit sized at wire gauge 65 (0.0350 inches decimal), designed for high-precision drilling in tight-tolerance applications. The 120-degree standard point angle provides accurate entry and reduces walking on hard or brittle materials. With a 30 mm overall length and a 1.50 mm straight-cylindrical shank, this bit fits standard micro drill chucks used in precision machining environments. The spiral flute geometry with a regular helix promotes efficient chip evacuation in small-diameter holes. The bright, uncoated finish suits applications where coating buildup could compromise dimensional accuracy.
This drill bit belongs to the Miniature series and is suited for precision drilling operations on circuit boards, instrument components, watch parts, medical device components, and other small-part manufacturing tasks. Right-hand cutting direction makes it compatible with standard CNC machining centers, drill presses, and hand-held precision drill units. It is installed by machinists, tool-and-die technicians, PCB fabricators, and precision metalworking shops requiring consistent performance at very small diameters.
Designed as an OEM-style replacement or direct-use micro drill bit for precision drilling applications requiring a wire gauge 65, straight-cylindrical shank tool in standard micro drill chucks and collet holders.
Installation should be performed by qualified machinists or precision tooling technicians familiar with micro-diameter tooling. Secure the shank fully in a properly sized collet or chuck before operation, and verify runout is within acceptable tolerance before cutting. At this diameter, excessive feed rate or lateral force will cause bit breakage. Always power down or lock out the machine spindle before changing tooling.
