Annular Cutter: Ø 45mm
Oneway to avoid dimpling and deburring while making holes in tube and pipe is to useannular cutters. Because annular cutters are hollow on the inside, there is no dead-zoneresistance to overcome.
Using a twist drill to make holes in pipe or tubing can prompt concerns aboutthe hole roundness, location accuracy, hole finish, chip extraction, burrs, anddrilling 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 cuttingangles intersect at the web of the drill, or the so-called 'dead zone.' This deadzone 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 multiplyyour cutting speed by up to 3 times while getting a longer tool life, a more accuratehole, a better finish, with no burrs. The cutting edges distribute the cutting loadevenly, thus making it faster cutting.
Annular cutters convert a smaller area to chips, requiring less horsepower andthrust. This feature provides longer tool life and less chatter. The slug also offersa higher scrap value than loose chips and shavings.
Refer to the picture shown below, explaining why annular cutters are more efficientand faster than twist drill bits.
