This 29-piece Drill America Cobalt Drill Bit Set is designed for professionals and serious DIYers who need to drill into hard materials like stainless steel and alloys. Its key benefit is extended tool life and superior performance in tough applications due to its M35 cobalt steel construction. A potential caveat is that these specialized bits may require appropriate lubricants for optimal performance and longevity, especially in extremely hard metals.

M35 cobalt steel contains 5% cobalt, which significantly increases its hardness, heat resistance, and wear resistance compared to standard high-speed steel (HSS). This allows cobalt bits to maintain their cutting edge longer when drilling hard or abrasive materials.
No, the 135-degree split point is designed to be self-centering and self-peircing, allowing you to start drilling into most materials without a pilot hole. It also helps reduce the tendency for the bit to wander.
The gold oxide finish provides an extra layer of wear resistance and lubrication. It helps reduce friction, dissipate heat, and prevent corrosion, contributing to a longer bit life.
Yes, these bits are compatible with standard drill chucks. However, for optimal performance and safety when drilling hard materials, it's recommended to use a drill with sufficient power and torque, and potentially a drill press for precision.
After use, clean any metal shavings or debris from the bits. Store them in the provided shatterproof plastic case to prevent damage and keep them organized. Ensure the case is closed tightly.
These bits are ideal for drilling into tough materials such as stainless steel, cast iron, alloys, titanium, and other hard metals. They can also be used on softer materials, but their primary advantage is in demanding applications.
Please refer to the manufacturer's documentation or contact customer support for specific warranty information, as it typically varies by product and region.
Ensure you are using adequate lubrication for the material, reduce drilling pressure, and check that the drill speed is appropriate. Avoid excessive side loading.
The 135-degree split point should prevent this. Ensure the bit is securely seated in the drill chuck and that you are applying steady, perpendicular pressure.
Verify the drill's RPM setting is suitable for the material. Increase the amount of cutting lubricant or coolant being used. Ensure the bit is sharp and not worn.
Withdraw the bit periodically while drilling to clear chips. The split point is designed to create smaller chips, but very hard materials can still cause buildup. Ensure you are not drilling too fast.
Setup: The drill bit set is ready for immediate use upon opening the case. Ensure the drill chuck is clean and free of debris before inserting a bit. Select the appropriate bit size for your application and secure it firmly in the drill chuck.
Compatibility: These bits are compatible with most standard drill chucks found on corded and cordless drills. They are designed for use with drills that have sufficient power and RPM capabilities for drilling into hard materials. For best results, use with a drill press for maximum stability and accuracy when drilling dense metals.
Care: To maximize the lifespan of your drill bits:
