Slow helix drills
WebbDifferent manufacturers will utilize different angles (i.e. 37° vs. 38° for HRSA materials). * Utilize a higher helix angle for free machining stainless steels and materials with lower machinability rate (more difficult to machine) such as Inconel, titanium, A286, etc. Summary. Using a higher helix when not necessary can reduce tool life; and using too … http://www.tapdie.com/html/slow_helix_drills_metric_slow_helix_drills_inch_slow_helix_drill.html
