Why choose it

The TiN coating increases surface hardness and reduces friction, extending tool life and improving chip evacuation. The precise h8 tolerance ensures consistent hole diameters, while the 118° point angle is ideal for general-purpose drilling.

Ideal use cases

• Drilling steel and cast iron components
• Machining non-ferrous metals like aluminium and brass
• Creating holes in plastic workpieces
• Use in drill presses or hand-held drills with cylindrical chuck

Good to know

This drill bit is ground from solid HSS, providing superior strength and concentricity compared to rolled bits. The gold TiN coating also aids in visual identification of the tool's performance class.
