## Summary description

Cobalt metal drill bit set AWTools AW42075 includes ten 7.5 mm high-speed steel bits with cobalt alloy for improved heat resistance and wear durability. Designed for drilling through steel and other metals, suitable for hand drills and drill presses. Provides stable penetration, longer tool life and consistent hole quality for metalworking tasks.

## Long description

AWTools AW42075 cobalt drill bit set contains ten 7.5 mm bits made from high-speed steel with a cobalt alloy. These drill bits are engineered for drilling metal, offering improved heat resistance and wear durability compared with standard HSS bits. The set is suitable for use in handheld drills and drill presses and is intended to deliver consistent hole quality and longer tool life when working with steel and similar metals.
Advantages
The cobalt alloy composition increases red hardness and heat resistance, reducing edge wear during continuous drilling in metal. A precisely ground geometry provides stable penetration and helps maintain hole size and surface finish over repeated use. Supplied as a set of ten identical 7.5 mm bits, it simplifies tool management for repetitive metalworking tasks.
Suitable for
Drilling holes in mild and stainless steel
Workshop tasks with handheld drills
Use on drill presses for repeatable hole patterns
Metal fabrication and repair work requiring 7.5 mm holes
When it may not be suitable
These cobalt HSS bits are optimized for metal and may not be the best choice for masonry, ceramic, glass, or wood applications where specialized bits perform better. For thin sheet metal, smaller diameter or specialized stepped bits might be preferable to reduce deformation. Very large-diameter drilling or high-volume production may require carbide tooling or coolant-fed setups for maximum life and speed.
Key specifications
Material: high-speed steel with cobalt alloy for improved heat resistance
Diameter: 7.5 mm
Quantity: set of 10 identical bits
Intended use: drilling metal (including steel and stainless steel)
Compatible tools: handheld electric drills and drill presses
How to use
Secure the appropriate bit in the drill chuck and clamp the workpiece to prevent movement. Mark the drill position and, if necessary, start with a center punch to prevent walking. Use moderate feed pressure and appropriate rotational speed for 7.5 mm cobalt HSS bits—lower speeds for harder steels and higher speeds for softer metals—while applying cutting fluid or oil to reduce heat and prolong bit life. Clear chips regularly and allow the bit to cool when drilling multiple holes in succession.
What to consider before purchase
Confirm that 7.5 mm is the required hole diameter for your application
Assess whether cobalt HSS is the right material for the metals you will drill (preferred for steel and stainless steel)
Check that your drill or press can provide appropriate speed and torque for 7.5 mm metal drilling
Usage recommendations
To maximize tool life and hole quality, use cutting fluid, select suitable speeds for the workpiece hardness, clamp the work securely, and periodically withdraw the bit to remove chips and allow cooling.
