Features:

• HSS-Co5 (COBALT) Stub drills 
• Bordo’s Cobalt stub drills are manufactured from HSS-Co5 steel which is very similar to M2 HSS with the important addition of 5% cobalt.
• The addition of cobalt to M2 HSS significantly increases heat resistance and allows the drill to run at higher temperatures without losing its temper (hardness).
• Cobalt drills provide increased performance and tool life when machining tough steels.
• HSS-Co5 (Cobalt) stub drills are ideal for use in drilling stainless steel and high tensile steel.
• Replacement screw extractors and HSS-Co5 left hand stub drill bits are available separately.
