SPHINX 81-687-6 HSS Micro Drill Bit 0.17mm Precision

SPHINX Spirec 81-687-6 HSS micro drill bit delivers a 0.17 mm (0.0067 in) diameter for precision micro drilling. Part of the SPHINX Spirec lineup, this high-speed steel (HSS) bit is designed to cut very small holes with consistent accuracy. The tool is identified by the part number 81-687-6 and is intended for micromachining tasks requiring tiny hole sizes. High-speed steel drill bits provide a balance of hardness and toughness for fine-hole work, helping maintain diameter control at small scales. Because the critical specification is the 0.17 mm diameter, this bit is suited for applications where exact hole size is essential.
