Frequently Asked Questions

Everything you need to know about our tools and services

What is an annular cutter?

An annular cutter is a specialized drill bit that cuts a hole by removing material only around the circumference, leaving a solid core. It's significantly faster and more efficient than traditional twist drills, especially in thick steel plates.

TCT vs HSS – which one should I choose?

TCT (Tungsten Carbide Tipped) cutters are ideal for hard materials and high-volume drilling, offering longer life. HSS (High-Speed Steel) cutters are more economical and suitable for general-purpose use, especially in softer metals.

What is a magnetic drilling machine?

A magnetic drilling machine uses a powerful electromagnetic base to securely attach to steel surfaces, allowing for precise hole drilling on vertical, horizontal, or overhead surfaces without clamping.

Can I use annular cutters on a regular drill press?

While possible, annular cutters perform best on magnetic drilling machines or core drills that provide proper alignment, high torque at low RPM, and internal coolant delivery.
