Frequently asked questions
What is a core drill used for?
It makes large diameter holes in sheet metal and metal, removing only the outer ring and leaving a central core.
Core drills are much more efficient than traditional drills on large diameters: they remove only the necessary material, reduce drill effort, and produce cleaner holes.
What steel is it made of?
From HSS (High Speed Steel), high-speed steel for most mild steels, aluminum, and standard ferrous materials.
HSS withstands temperatures up to 600 °C without losing sharpness. For hardened materials or mass production, consider HSS-Co versions or those with hard metal inserts.
Which machine is it mounted on?
It is mounted on magnetic drills (core drilling machines) and milling machines with standard Weldon or TCT shank.
Magnetic drills are the most popular choice for core drills, thanks to their strong magnetic adhesion and controlled feed. Check the shank type before purchasing.
What drilling depth does it reach?
Bernardo core drills are available with 30 mm (short version) or 55 mm (long version, KBL/CDL) depth.
For thicknesses up to 30 mm, the short version is optimal (more rigid). For thicknesses 30-55 mm, the long version is needed. Greater thicknesses require custom drills.
How is it lubricated during machining?
Use cutting oil or cooling emulsion applied directly to the cutting point. Coolant reduces heat and extends useful life.
On hard steels or high thicknesses, lubrication is essential: without coolant, the drill overheats, loses sharpness, and can break prematurely. Recommended cutting speed: 20-30 m/min on mild steel.
