Key item features

  • Enhanced Stability: The four flute step drill bit design reduces deflection during cutting, providing greater stability and improved accuracy.
  • Durable Material: Made from M35 cobalt high-speed steel (HSS), offering high hardness (HRC 64-66), red hardness, and wear resistance for tough jobs.
  • Advanced Coating: TiAlN coating provides exceptional hardness, high oxidation temperature resistance, and excellent thermal hardness, making it ideal for demanding applications.
  • Efficient Drilling: The 135-degree cutting angle reduces self-wear and provides a larger stress area, resulting in cleaner and more efficient drilling.
  • Versatile Use: Suitable for drilling metal, wood, stainless steel, and plastic, making it a versatile tool for various materials.
  • Maintenance Tips: To maintain optimal performance, add cutting oil or spray water to cool during continuous use, and note that start-up speed may be slower due to the larger cutting angle.

Good quality

I haven't used the bits yet but they have good sharp edges. edges are clean as well. I'm planning on using these do make holes for trailer lights. so I'll have plenty of 3/4" holes to drill
