The D2129 3/8" Cobalt Drill Bit
This Cobalt Drill Bit, designated as D2129, is designed for the machining of high tensile steels and challenging alloys, featuring a 135° split point.
Due to their resistance to heat and stress, cobalt alloy bits can operate at higher speeds without overheating.
The 135° split point characteristic reduces the need for excessive force during drilling, minimizing the drill point's tendency to wander. This makes the bit suitable for use in both portable drills and drill presses.
In comparison to High-Speed Steel bits (HSS), cobalt alloy bits maintain sharpness for an extended period, resulting in notable time and cost savings in workshop applications.
The D2129 is backed by a 1-year warranty, ensuring freedom from factory defects.
