Countersink from BAER for a secure finish
The utmost care is required when working with metal, because sharp edges that pose a risk of injury and protruding burrs develop particularly quickly here. The edge of a drill hole in particular is susceptible to residues of the material, which not only look unsightly but can also quickly cause small cuts and scratches. To counter this problem, the taper countersink or borehole countersink is your tool of choice.
The countersink deburrs the drill hole and countersinks it, for example to countersink screws, so that they disappear completely into the workpiece. So not only do you remove sharp-edged residues, you also create a clean finish and a comfortable starting situation for further work, e.g. with a precision threading tool such as the tap. With a drill hole countersink, you will succeed in creating a flush surface of your workpiece without any disturbing unevenness.
As specialists in all aspects of tapping, taper countersinks are especially close to our hearts at BAER. Countersinking is not only a small but important step on the way to a perfectly cut thread. It also ensures a professional-looking end result that can't be beat for cleanliness and precision. We want you to be completely satisfied with your work. That's why you'll find the right taper countersink for your project at our Online-Shop. Take a look around and see for yourself!
This is the conical countersink: Compact design with great effect
The design of the taper countersink is as simple as it is effective. The conical head is defined by its maximum diameter and the countersinking angle. The diameter indicates the bore sizes for which the countersink is suitable. You select the countersinking angle according to your application. The range extends from 60° for pure deburring to 120° if you want to use the countersink for countersinking sheet metal rivets. The most common angle, however, is 90°, because this angle is suitable for countersinking commercially available countersunk screws. The cutting edge in the head of the countersink ensures that the material is removed, and the groove profile removes the abrasion. The shank of the countersink differs according to the machine with which you use it. The most common is a cylindrical shank, for use in hand drills there are also countersinks with a bit shank.
In addition to the classic form of the countersink, there are also some special variants for special cases. The transverse countersink has a larger head shape in which an opening is made. This results in a peeling cut. The chips are not discharged via a groove, but upwards through the opening in the drill head. This effectively prevents material residues from jamming in the workpiece. For countersinking cylinder head screws or hexagonal screws, you need a flat or tang countersink. Slip-on countersinks can simply be attached to an existing twist drill and are particularly suitable if you only rarely need a taper countersink.
On one view
Existing holes are reworked with the countersink:
- Deburring - for smooth cut edges
- Sinking - for countersinking screws
