A PTC carbide drill bit that has spun inside the chuck during use will not be running at the correct speed and could even stall momentariliy

The 3-stop pivoting head provides unmatched access by allowing users the ability to adapt the tool for the application and solder in more confined spaces

29/64" HSS Drill Bit Long Series Carded 2500-29/64S by Bordo CNC Router A PTC carbide drill bitBLACK FINISH (also called blue finish) A black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating. This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life. Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation. Specifications:
