What is a chamfer drill?
A chamfer mill, or a chamfer cutter, is one of the most common tools used by machinists daily. When creating a part, machining operations can oftentimes leave a sharp edge on a workpiece. A chamfer mill eliminates sharp edges, leaving a sloped surface, or a chamfer, instead.
What tool is used to cut a chamfer?
A chamfer cut can be made using a V-groove or chamfer router bit. Bevel bits can also make chamfers, but the angle of these bits is likely to be different to chamfer cutters. A chamfer cut is often made when constructing a mitre joint.
Can you use a spot drill to chamfer?
Spot drills are also applied for chamfering a hole prior to drilling. The spot drill is taken deep enough to create the desired chamfer diameter while spotting the hole.
What is chamfer machining?
In machining a chamfer is a slope cut at any right-angled edge of a workpiece, e.g. holes; the ends of rods, bolts, and pins; the corners of the long-edges of plates; any other place where two surfaces meet at a sharp angle.
Is chamfer and countersink the same?
A countersink and a chamfer are very similar. A countersink is basically no different than a chamfer on a hole. The main difference is that a chamfer is normally thought of as being at 45 degrees (though the angle can vary). A countersink is usually one of many different standard angle sizes.
What is chamfer in woodworking?
A chamfer is essentially a bevel cut along an edge or across a corner, as shown in the drawing above. Although a chamfer doesn’t have to be cut at 45° to the adjacent surfaces, this is the most common angle. A flat profile cut at a shallower angle is often simply referred to as a bevel.
What are spotting drills used for?
A Spotting Drill’s purpose is to create a small divot to correctly locate the center of a drill when initiating a plunge. However, some machinists choose to use these tools for a different reason – using it to chamfer the top of drilled holes.
