How to choose the right HSS-Co cobalt milled drill bit with taper shank for metal
When selecting a drill bit, the most important factors are the material being drilled, the required hole diameter, and the type of machine where the drill bit will be mounted. The HSS-Co cobalt design is especially suitable for more demanding drilling into harder metals where higher heat resistance and longer tool life are required.
Material you will be drilling into
For stainless steel, titanium, and other tougher or more heat-demanding materials, HSS-Co is a better choice than standard HSS. The higher heat resistance helps maintain better cutting performance even during demanding work.
Drill bit diameter and clamping method
In this category, drill bits are available in diameters from 9 mm to 50 mm. The taper shank is designed for mounting in pillar drills and industrial drilling machines with a Morse taper, where strength, stability, and reliable power transfer are important when drilling larger diameters or more demanding materials.
Drill bit construction
The milled drill body is suitable for both regular and more demanding metal drilling applications. The 118° point angle ensures quick positioning into the material and stable engagement during work.
Where and how HSS-Co cobalt milled drill bits with taper shank for metal are used
These drill bits are used wherever drilling into harder metal materials is required and where tool resistance to heat and wear is important. They are especially suitable for workshops, metalworking operations, maintenance work, and industrial environments where demanding materials are regularly processed.
- drilling into stainless steel,
- drilling into titanium,
- drilling into copper alloys,
- drilling into aluminium alloys,
Thanks to the taper shank, they are especially suitable for use in pillar drills and industrial drilling machines with Morse taper fitting, where firm and precise drill bit seating is required.
How to work with HSS-Co cobalt milled drill bits with taper shank for metal
When drilling into harder metals, it is important to work with attention to tool heating and smooth cutting performance. Even a more resistant cobalt drill bit requires proper working conditions to maintain its properties for as long as possible.
Lubrication and cooling
For longer drill bit life, we recommend using cutting oil, cutting and drilling spray, or cutting paste. These lubricants reduce friction, help limit overheating, and improve drilling efficiency.
Stability during work
During work, it is important that the drill bit is correctly mounted and guided. Especially with larger diameters and when drilling harder materials, stability has a major impact on both the result and tool life. These drill bits are designed for pillar drills and industrial drilling machines with Morse taper fitting, which provide the necessary stability and precise tool guidance.
How does the selection continue?
This category is not further divided. Here you will find a standalone selection of HSS-Co 5% milled drill bits with taper shank in various diameters.
