Aircraft Dynamics Black Widow Drill Bits (22 Sizes) (15/16" Dia x 18" Long)

The Aircraft Dynamics Black Widow Drill Bits are designed to deliver unparalleled speed and precision, making them an essential tool for linemen tackling tough pole drilling jobs. Renowned as the fastest and cleanest drilling pole bits on the market, they offer a combination of durability, efficiency, and performance. With a 7/16" hex shank for secure attachment, these rugged, heat-treated drill bits are built to withstand some abuse. The proprietary flute design ensures optimal wood chip removal, while the self-feeding screw and cutting spur easily slice through even the hardest treated wood poles, cutting average drilling times by up to 50%. Each cut produces a clean, smooth hole. Black Widow Drill Bits are available in 18" and 24" lengths, with a variety of diameters to suit different applications. However, it is important to note that all bits 1" in diameter or larger are not intended for use with impact tools. For linemen seeking reliable and efficient tools, Black Widow Drill Bits are a fantastic choice for superior performance & precision.
