Why choose it

The TiAlN coating significantly reduces friction and heat build-up, allowing higher cutting speeds and extending the drill bit's service life. The split point design ensures accurate centering and reduces walking, while the reinforced core provides stability during deep-hole drilling. The h8 tolerance guarantees precise hole dimensions for demanding applications.

Ideal use cases

• Drilling large-diameter holes in steel plates and structural components
• Machining stainless steel parts in metal fabrication
• Creating precise holes in cast iron housings
• Working with non-ferrous metals like aluminum and brass
• Drilling plastics in industrial settings

Good to know

This drill bit is designed for use with stationary drilling machines or powerful hand drills with suitable clamping. The cylindrical shank fits standard drill chucks. The TiAlN coating gives the bit a characteristic bronze/anthracite colour. For best results, use appropriate cutting fluid and follow recommended speed and feed rates for the material being drilled.
