Some time ago we published a blog entitled, "CUTTING TAP CHAMFER 101”. It described what the chamfer’s purpose is, and what standard lengths are offered on off the shelf taps. They are Bottoming, Plug, and Taper. This blog builds on that information and goes into more depth so you can optimize the chamfer based on your application. Although we stock many common special taps with standard chamfer lengths, we can design and manufacture a special tap for your application. Optimizing the chamfer results in, longer tap life, reduced tapping torque, better finish, and make the difference
Most cutting taps are available in three chamfers. Taper, plug and bottom are how they are referred to in most of the current literature. Why do we choose one over the other and what are the advantages?
Unlike a drill or center cutting end mill, taps introduce the cutting edges by means of a chamfer. Drills are cutting on the tip (axial), center cutting end mills plunge (axial) then may traverse to cut radially on the workpiece. Most end mills are cutting on the radius, but they are to leave a “straight” or “smooth” finish.Read More
