  • High hardness step drill bit: This product is M35 cobalt containing step drill, with very high hardness, especially suitable for drilling high hardness steel plates, such as stainless steel plates and quenched steel plates. It can handle some tasks that traditional HSS4241 ladder drills are difficult to complete.
  • Spiral groove design: The product has spiral grooves, which can achieve faster, more stable, and smoother drilling. The double groove design helps to quickly remove debris while allowing particles to easily escape. This improves work efficiency.
  • Multiple operation methods: You can use a hand drill or a table drill for operation. Hand drills are suitable for cutting boards within 1mm, while table drills are suitable for boards between 2-3mm, thus providing greater flexibility.
  • Widely applicable: This product is suitable for drilling various materials, including stainless steel, iron, hard metal plate, plastic, aluminum, copper, iron sheet, and other metal plates. It is a universal tool suitable for various work situations.
  • Cooling recommendation: When using, it is best to inject water or use cutting fluid for cooling, which can effectively extend the service life of the drill bit, especially when dealing with high hardness materials.
