What is an annular cutter set?
An annular cutter is similar to a hole saw but differs in geometry and material. ... Like a hole saw, but unlike a spiral drill bit, an annular cutter cuts only the periphery of a hole, leaving a circular "slug" at the center. Annular cutters are available from 12 mm (1/2'') diameter to 200 mm (7 7/8'') and larger.

How accurate are annular cutters?
Annular cutting, the cutting of metal with a hollow-core bit, is an efficient way to create holes 7/16" to 6" diameter (up to 10" deep) with an accuracy of +0.004", -0.000" in steel, stainless steel, etc. Multiple cutting teeth cut only the material around the periphery of the hole, forming a solid metal slug.
What is an annular cutter used for?
An annular cutter is a specialized bit for drilling through metal. Like a hole saw for wood, an annular cutter only cuts the outside edge of a hole. It produces accurate burr-free holes to close tolerances without pre-drilling or step drilling.
