Why choose it

The Pro-Tec line combines premium HSS steel with precision CNC grinding, ensuring clean, chatter-free holes even in tough materials. The 124° split point reduces walking and requires less feed pressure, making it ideal for both professional workshops and demanding DIY projects.

Ideal use cases

• Drilling mild steel, stainless steel, and sheet metal
• Creating precise holes in cast iron components
• Working with aluminum, brass, and copper
• General maintenance and repair tasks in automotive and industrial settings

Good to know

For best results, use cutting fluid when drilling steel and reduce speed for larger diameters. The set's incremental sizing covers virtually all common metric hole requirements, eliminating the need for multiple individual purchases.
