When talking about V Bits what is the difference between those and countersink bits? I know both of their uses, but they look exactly the same and have parallel purposes. Have you ever heard of anyone using a countersink for a V Bit or Vice Versa?
-Thanks, Levi
A countersink bit tends to have more flutes, which are not as deeply fluted, so there isn’t as much chip clearance in the interest of rigidity since it is expected that they will be used with metals.
V endmills have fewer flutes and much better chip clearance and are suited to a wide range of materials, but can require care in metals, esp. re their tips.
Countersink bits are various angles.
Countersunk -head screws that follow the Unified Thread Standard very often have an 82° angle , and screws that follow the ISO standard very often have a 90° angle . Throughout the aerospace industry, countersunk fasteners typically have an angle of 100°.
From the above info when you say countersink you have to specify which angle bit you have. As you can see there are a lot of angles so you would need to measure your bit. As with many tools I can drive a nail with a glass vase but it would work better with a hammer. So would be true with vcarving it is better done with a tool made to do that instead of something that might work.
