What is deburring chamfer?
Chamfering and deburring, two terms used in parts fabrication, describe processes for finishing machined parts. Chamfering means to make a bevel, groove or furrow. Deburring is to remove any rough ridges, edges or areas from a part after shaping.
What is a chamfer tool?
A chamfer is a bevelled edge of 45 degrees, cut into the material using a chamfer tool bit or deburring tool. A chamfer can be used to smooth sharp or hazardous edges on a workpiece. Chamfering a workpiece prevents material from breaking or tearing away from the workpiece edge.
How is chamfering done?
Chamfering is making a small cut, usually at a 45 degree angle, to remove a 90 degree edge. Chamfering is used in woodworking, in glass cutting, in architecture, and in CAD, and it’s also a useful tool for deburring. Chamfer is a noun as well as a verb, and is also frequently used as the name for such a cut.
What is the common angle of a chamfer?
Threaded-hole chamfers normally have included angles of 120° or 90°, with 90° being most common. The OD and depth of the chamfer sometimes are specified on the blueprint. However, it is frequently left to the discretion of the machinist or programmer to determine the depth or OD of the chamfered hole.
What is the difference between a chamfer and a bevel?
A chamfer is technically a type of bevel, but the difference between the two is that a bevel is an edge that is sloped and a chamfer is an edge that connects two surfaces at a 45-degree angle, while a bevel’s slope can be any angle except 90 or 45 degrees.
How do you chamfer holes?

Is a chamfer always 45 degrees?
Unlike the hypotenuse that connects one part to another, the chamfer transitions between two right-angled surfaces of the same part. Unlike a bevel, the chamfer is always at a 45-degree angle. Chamfering can remove the sharp edges of the 90-degree angle of the part to prevent injuries during handling.
Why chamfer is required?
Chamfering eases assembly, e.g. the insertion of bolts into holes, or nuts. Chamfering also removes sharp edges which reduces significantly the possibility of cuts, and injuries, to people handling the metal piece.
How do I know my chamfer size?

Why do we use chamfer?
Chamfers are used in furniture such as counters and table tops to ease their edges to keep people from bruising themselves in the otherwise sharp corner. When the edges are rounded instead, they are called bullnosed. Special tools such as chamfer mills and chamfer planes are sometimes used.
How do you chamfer an edge?
To create a chamfer on an edge,
- Click Modeling and then, in the Engineering group, click the arrow next to Chamfer.
- Click Distance, Dist / Dist, or Dist / Angle.
- Select a Type: Distance, Dist/Dist, or Dist/Angle.
- Click Chain Selection if you want to select all tangentially connected edges with a single click.
Is chamfer and countersink the same?
Countersink vs chamfer
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 the normal size of chamfer?
0.010″ to 0.015″
The most common practice is to apply a chamfer diameter that is 0.010″ to 0.015″ (0.254mm to 0.381mm) larger than the thread’s major diameter. This will eliminate the burr and provide enough depth to act as a starter for a mating bolt.
Does a chamfer have to be 45 degrees?
Unlike a bevel, the chamfer is always at a 45-degree angle. Chamfering can remove the sharp edges of the 90-degree angle of the part to prevent injuries during handling. Chamfering can also protect the corners of the part from damage, thereby improving the overall integrity of the part.
What angle is a chamfer usually?
The most common standard chamfer design is a single chamfer, but there are also tools with two or more chamfers [2]. The chamfer angle ranges typically from 20 to 45°, and the chamfer width, 90-degree lead angle in turning, is usually kept below 30% of the feed [1].
How does a chamfer work?
A chamfer occurs whenever you have two surfaces meeting at an angle other than 90°, especially 45°, but instead of a point they terminate at a flat edge, which has the effect of “rounding” out the corner.

What size chamfer do I need?
The most common practice is to apply a chamfer diameter that is 0.010″ to 0.015″ (0.254mm to 0.381mm) larger than the thread’s major diameter. This will eliminate the burr and provide enough depth to act as a starter for a mating bolt.
Can you use a countersink for chamfer?
A countersink can also be integrated into a step drill where the drill can create the hole and the chamfer in a single operation.
How do you know what size chamfer to get?
If a chamfer is called out as a face width, then it is to be measured along the hypotenuse of the chamfer. To convert a leg length dimension to face width simply multiply the leg length value by 1.414. To convert from a face width dimension to a leg length dimension, reverse the process and divide by 1.414.

Can you chamfer with a router?
Wood edges can be chamfered particularly easily with the handy OFK 500 edge router, which can be used universally.
Which is better chamfer or fillet?
Fillet gives better stress flow (less resistance) compared to chamfers. Fillets generally give a lower stress concentration factor than chamfers . Chamfers are more forgiving when fitting mating parts. i.e. even if there are inaccuracies in a chamfer mating parts might fit together.
