## Summary description

Cobalt metal drill bit set AWTools AW42105 — five 10.5 mm HSS-Co drills designed for drilling hardened and stainless steels and other metals. Cobalt alloy increases heat resistance and durability for higher penetration and longer life. Suitable for professional and workshop use with hand drills and drill presses.

## Long description

AWTools AW42105 cobalt drill bit set for metal contains five 10.5 mm high-speed steel bits with cobalt alloy designed for drilling hardened and stainless steels as well as a range of other metals. The HSS-Co composition increases heat resistance and cutting edge strength, making these bits suitable for continuous or intermittent metalworking tasks with hand drills and drill presses in professional and workshop environments.
Advantages
The cobalt alloy in these 10.5 mm drill bits improves durability and thermal stability compared with standard HSS, enabling higher cutting speeds and reduced wear during drilling of hard or heat-generating materials. The set of five ensures quick replacement of worn tips for uninterrupted work. The bits are ground to deliver consistent drilling performance and straight holes in various metal types.
Suitable for
Drilling hardened steels and stainless steel
General metal fabrication and maintenance tasks
Use with hand-held drills and drill presses
Workshop and professional mechanical applications
When it may not be suitable
These cobalt HSS bits are optimized for metal and may not be the best choice for wood, masonry or ceramic materials; specialized bits for those substrates will give better results. For very large-diameter holes or production setups requiring carbide tooling, carbide or indexable tooling may offer longer life and higher productivity.
Key specifications
Material: high-speed steel with cobalt alloy (HSS-Co)
Diameter: 10.5 mm
Set contents: 5 drill bits
Intended use: drilling metals including hardened and stainless steels
Compatibility: hand-held drills and drill presses
How to use
Select an appropriate cutting speed and feed rate for the metal being drilled to reduce heat buildup; lower speeds are recommended for stainless and hardened steels. Secure the workpiece firmly and use a center punch for accurate hole placement when necessary. Apply cutting fluid or lubricant to improve heat dissipation and prolong bit life. Back the bit out occasionally to clear chips when drilling deep holes and allow the bit to cool between prolonged operations.
What to consider before purchase
Confirm 10.5 mm diameter suits your application and fastener or component requirements
Consider material being drilled—these bits are designed for metals, especially hard and stainless steels
Ensure your drill or press can run at appropriate speeds and has sufficient rigidity for metal drilling
Plan for cutting fluid and safe clamping methods to maximize bit life and hole quality
Usage recommendations
Use moderate feed pressure, maintain steady speed appropriate for HSS-Co, and employ coolant when drilling stainless or hardened steels. Replace bits in the set when you observe significant dulling or chipping to avoid poor hole quality and increased torque on the drill.
