High performance drilling
AlTiN coating has wear-resisting and heat resistance
140 degrees of separation, easy to start
It’s easy to drill five deep
High performance drilling using high pressure coolant, with a point bit of 140 degrees of AlTin coating, will accelerate the production of mOHDerate feed at a high speed. In difficult drilling conditions, the evacuation and heat dissipation of the chip extend the drilling life.
The cobalt drill bit
The RL cobalt drill is made of high quality cobalt steel and has excellent hardness and is very wearable. The RL high quality cobalt drill reduces the cost of each drill for your tool life than the normal cobalt drill. These cobalt drills are designed for drilling and grinding materials, high temperature alloys, stainless steel and high-strength steel for heat treatment. The minimum cost per drill of RL cobalt drill.
After more than 100 years of drilling experience, RL has perfected the design, providing you with the best best penetration and flute geometry, ensuring continuous chip ejection. Our strict quality control and heat treatment methods ensure the performance of our high-quality cobalt bit.
