Stainless steel drilling faster with R563 CDX-Inox drill

R563 CDX-Inox Drill offers exceptional levels of performance and tool life when drilling to depths of up to 5x diameter in stainless steels and exotic alloys. Stainless steels are difficult to machine materials, most work harden during deformation and are poor heat conductors, leading to high cutting edge temperatures. To combat this, the R563 has a thin margin which reduces contact with the hole surface. This minimises friction between the drill cylindrical land and the hole walls, decreasing work hardening and temperatures generated. Due to the high toughness of stainless steel, problems with chip breaking and swarf management are commonplace. The R563’s positive geometry and coolant feed holes ensure excellent chip breaking and evacuation. These features also reduce the smear of the material to the edges of the drill. Tool life is further enhanced by the smooth, curved design of the cutting edge which results in a uniform wear pattern. In addition, the 140° point design promotes excellent centring and hole tolerance, and ensures that the thrust forces exerted at high penetration rates are low. In tests against competitor drills machining 316L stainless steel, the R563 drilled an average of 175% more than the nearest equivalent (134 metres compared to 48 metres), with cost-per-hole savings up to 12 times higher.
