Cobalt drill bits provide superior specialized performance. These bits are needed for extreme high heat encountered with drilling in hard metal, heat-treated steel and stainless steel.
- High speed steel with 5 percent cobalt content for strong durable performance in hard metal drilling applications.
- Twist drill bit made of alloyed high speed steel to DIN 338, cobalt content 5 percent.
- Twist drill bit ground from solid metal with excellent surface quality manufactured to special factory standards.
