Why choose STROTON cobalt drill bits?

The research shows that HSS with cobalt has a higher temperature resistance and Red hardness, a greater wear resistance(Hardness) and a higher heat treat response than HSS without cobalt .

Red hardness, it causes the hardened steel to have an ability to maintain hardness at approximately 860-880 °C .

66-69 HRC,it means that the drill bits has 3X cutting ability and 3X durability.

This drill bits set is made of Premium Cobalt (80,000 dollars per ton).

This drill bits set definitely have more cobalt in them than the "Cobalt" bits that HF sells--which are just Cobalt coated or only a tiny amount of cobalt tipped.

Compared with ordinary high speed steel, 5% cobalt provides better heat and wear resistance,and Hold up Better.

Split Point design tip starts drilling immediately with less force and eliminates "walking" across the work surface.

Ideal for Stainless steel,Hardened Steel,Cast Iron,Aluminum,Copper,Plastic and Hardwood.

The drill bit can be used for mechanical maintenance, such as drilling out bolts and screws.

Non-vertical use may cause the drill bit to break.

Using a drill press with sufficient power will make drilling easier.

Too high speed may burn the bit tip.

Drill bits diameter:

1/16≤3/16,RPM(1000~700)

3/16-3/8, RPM(700~350)

3/8-1/2, RPM(350~200)

Add Cutting Fluid or engine oil to prevent the stainless steel from overheating.

It also works adding some vinegar, soy sauce or water.

The drilling shall be started slowly by applying force slowly and gently until the drill bit starts chipping.
