ANNULAR HOLE CUTTER HSS 24 X 55MM BROACH SLUGGER BIT IN SOUTH AFRICA

Annular Cutters 55mm long Annular Cutter: Ø 24 mm One way to avoid dimpling and deburring while making holes in tube and pipe is to use annular cutters. Because annular cutters are hollow on the inside; there is no dead-zone resistance to overcome. Using a twist drill to make holes in pipe or tubing can prompt concerns about the hole roundness; location accuracy; hole finish; chip extraction; burrs; and drilling duration. The focal point of these concerns is the twist drill's most noticeable feature; its point. This is not really a point at all; but the tangent line where two cutting angles intersect at the web of the drill; or the so-called 'dead zone.' This dead zone causes the surface speed of the cutting edges to drop to zero. The lower surface speed reduces cutting efficiency and requires increased thrust; or feed pressure; for the cutting edges to push through the material. Compared to traditional tooling (twist drills; etc.) annular cutters can multiply your cutting speed by up to 3 times while getting a longer tool life; a more accurate hole; a better finish; with no burrs. The cutting edges distribute the cutting load evenly; thus making it faster cutting. Annular cutters convert a smaller area to chips; requiring less horsepower and thrust. This feature provides longer tool life and less chatter. The slug also offers a higher scrap value than loose chips and shavings. Refer to the picture shown below; explaining why annular cutters are more efficient and faster than twist drill bits. Definition - Annular 'Ring-shaped' or 'forming a ring'.
