FAQ: 1-1/8" Diameter Carbide Tipped Annular Cutters What Pilot Pin size do I need for a 1-1/8" Diameter Carbide Tipped Annular Cutter? Always match the pin length to the cutters cutting depth. Do I need cutting fluid with carbide tipped annular cutters? Yes — cutting fluid dramatically improves cutter life, reduces heat, and improves slug ejection. Carbide can cut dry, but lubrication extends tool life and prevents tooth chipping. What's the difference between carbide tipped and high speed steel (HSS) annular cutters? Carbide tipped cutters are faster, more durable, and ideal for tough steels. HSS cutters are more forgiving, cheaper, and better for general-purpose mild steel drilling. How long do carbide tipped annular cutters last? Most carbide TCT annular cutters last 50–150 holes under normal use. With proper lubrication and correct RPM, you can often get even more. What's the difference between a Carbide Tipped Annular Cutter and a Carbide Tipped Hole Cutter? Annular cutters are for deep holes in thick steel using mag drills. Hole cutters are for thin metal using handheld drills.
