Drilling inserts are a core component in modern CNC drilling. As the "teeth" of indexable drill bits, they are designed to improve efficiency and reduce costs. Compared to traditional solid drill bits, their indexable nature allows for quick replacement after the cutting edge wears, eliminating the need to discard the entire tool and significantly saving on consumable costs. Our Carbide Drilling Inserts utilize advanced chip groove technology and an internal coolant hole design to ensure smooth chip removal and excellent hole surface finish when machining steel, cast iron, and stainless steel.
SPGT high-efficiency indexable drilling inserts are your professional solution for conquering drilling challenges. Featuring a unique chip breaker design, they precisely break chips into regular, small fragments, ensuring smooth chip removal, effectively protecting hole wall finish, and enabling safe and efficient automated machining.
