What is an annular cutter?
An annular cutter is a ring-shaped cutter that only cuts the hole perimeter, making it faster and more accurate than a twist drill for large holes in steel. It is used on magnetic drills.
Which Kertz annular cutter sizes are available?
The 50 mm (KZM) and 35 mm (KZS) series come in diameters from about 12 to 50 mm. The full size list is on the Kertz product pages.
What does TCT mean?
TCT (tungsten carbide tipped) means the cutting tips are tungsten carbide, harder and more heat-resistant than HSS, suited to structural steel.
What are the benefits of the Würth Quadro bit?
Per the Würth catalogue, the four-cutter head and four flutes give precise drilling with fast dust removal.
