How to select the right screw machine drill bit for horizontal drilling?
For horizontal drilling, choose a screw-machine-length bit with a 135° 4-facet point to minimize walking and thrust. Carbide material suits harder workpieces. The slow spiral flute aids chip evacuation in deep or gummy materials. Match the diameter (e.g., 0.4040 in) to your hole tolerance.
