Cobalt HSS Drill Bit Set – Key FAQs

• What does M35 with 5% cobalt mean?
  M35 is a cobalt alloy high speed steel, and the 5% cobalt content improves heat resistance and wear resistance for tougher drilling work compared with standard HSS.

• What is the benefit of a 135° split point?
  A 135° split point helps the bit start more accurately with less wandering, particularly on metal surfaces.

• What sizes are included in this set?
  You get 1.5mm, 2mm, 3mm, 4mm, 5mm, 5.5mm and 6mm, covering common small-to-medium drilling sizes.

• Should I use coolant when drilling?
  using a cooling agent/cutting fluid helps control heat, improves cutting performance and extends bit life, especially in metal.

• Are these suitable for general DIY use?
  Yes—these are ideal for both DIY and trade users who want cleaner starts and improved durability when drilling metal.
