Hello folks,
My brother in law wants some help to drill a shallow 3mm diameter hole into the barrel of his darts to reduce some weight. I took out my HSS drill and mounted the barrel in my ER collet chuck. My HSS drill only manage to create a small dimple no matter how I hard I try.
I'm wondering what I should get to drill the shallow hole. Cobalt? Tungsten Carbide?
Regards,
Wongster
