WHAT IS ANNULAR CUTTER?

Annular cutter (also called as slugger cutter,slugger bits,broach cutter ) is form of core drill used to create holes in metal,annular cutters, named after the annulus shape, cuts only a groove at the periphery of the hole and leaves a solid core or slug at the center.

Annular cutter is a more efficient alternative to spiral drill bits and standard hole saws,annular cutter is similar to a hole saw but differs in geometry and material,an annular cutter cuts only the periphery of a hole, leaving a circular "slug" at the center.

The two most common types are high-speed steel (HSS) annular cutter and tungsten carbide tipped (TCT) annular cutter.

COMPARE WITH HSS ANNULAR CUTTER AND WHY YOU SHOULD CHOOSE TCT ANNULAR CUTTER?

The biggest advantage of TCT annular cutters is speed and ease in which it may cut harder materials,especially for boring larger diameter holes in hard materials, TCT cutters can be used to great success.

The linear speed requirement is higher than that of HSS.

The teeth on TCT annular cutters are harder than HSS, allowing them to cut more difficult materials.
