Core Drill 21 mm
Core drills made of high quality HSS M2 steel for best possible sharpness and durability. Suitable for use with magnetic core drilling machines or pillar drilling machines with 19 mm (3/4") weldon Chuck. Perfect for optimal drill results in a short period of time, combined with cost reduction compared to standard drill bits. Core Drill cuts only a ring and not the entire drill diameter, saving you both time and money. The time saving is 10 times compared to a standard drill. Preparations such as centering and pre-drilling are not required. Core Drill has a very long tool life because of reduced material tension.
Always use coolant and optimal speed of the machine.
