Draper Expert HSS Metric Tap Drill Bit

The 6.8mm Draper Expert HSS Metric Tap Drill Bit is engineered for drilling pilot holes before using 8 x 1.25 metric taps. Measuring 6.8 x 181mm overall, this extended length drill bit combines the precise diameter required for M8 threading with the reach necessary for deeper hole applications. The high speed steel construction ensures durability and maintains cutting performance throughout extended use. This size is particularly valuable for larger mechanical assemblies, structural work, and applications where 8mm metric threads are required in thicker materials. The extended length format provides versatility for a wide range of drilling depths whilst maintaining the accuracy essential for successful tapping operations.
