Heavy Duty Bits
Cobalt Drill Bits drill through hard or abrasive materials such as :
Stainless Steel ~ Titanium ~ Cast Iron
Cobalt Drill Bits are also great at drilling through :
Aluminum ~ Brass ~ Copper ~ Sheet Metal ~ Wood ~ Plastic
135 Degree Split Point
Heavy Duty web construction for Strength & Durability
Standard Jobber Length (Fits into a regular drill index box)
Stronger ~ Cobalt Drill Bits are made of Cobalt blended into molten high speed steel, making the drill bit incredibly hard. Cobalt gives drill bits superior resistance to heat and abrasion, staying sharp longer, and their hardness produces almost no flexing. Cobalt bits are actually made with the Cobalt throughout compared to titanium which is only a coating over a high speed steel drill bit. Titanium is only a thin layer coated on the outside!
Faster ~ 135 degree split point begins drilling immediately. Cobalt Drill Bits don't wander like HSS bits either. And they require less effort to drill.
Lasts Longer ~ Cobalt Drill Bits are much more durable ~ Cobalt Bits last up to 30 times longer life than HSS drill bits & up to 5 times longer than Titanium bits! Plus since the Cobalt runs all the way through the bit - they can be sharpened over and over!
Best Value ~ Professionals use Cobalt Drill Bits to reduce costs and effort in high volume drilling applications where their much longer life really pays off, producing higher precision, less down time, and higher reliability. Professionals have come to realize their long life makes them a much cheaper alternative with longer sharpness, higher precision, less breakage and downtime, and they can be sharpened repeatedly!
