Product Description
Why Choose Premium STROTON Cobalt Drill Bits?
Researches have shown that compared with HSS without cobalt, HSS with cobalt has higher temperature resistance, red hardness, wear resistance and heat treatment response.
- Red hardness, which means that the drill bits hardened steel can maintain hard at 860-880℃.
- 68 HRC,it means that the drill bits has 3X cutting ability and 3X durability.
- This drill bits set is made of True Premium Cobalt (80,000 dollars per ton).
Truly Made of 5% Cobalt Alloy Steel
- 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.
3X Drilling Efficiency + 3X Tool Life

- Ideal for Stainless steel,Mild Steel,Iron,Hardmetal,Aluminum,Copper,Plastic and Hardwood.
- The drill bit can be used for mechanical maintenance, such as drilling out bolts and screws.
Be vertical to the workpiece
- Non-vertical use may cause the drill bit to break.
- Using a drill press with sufficient power will make drilling easier.
Low speed: 200 to 1000 RPM
- Too high speed may burn the bit tip.
- Drill diameter≤3/16，RPM（1000~700）
- 3/16-3/8，Rʲ（700350）
- 3/8-1/2，Rʲ（350200）
Use cutting fluid

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