The SNAP tool is an efficient front and back chamfering tool that is easy to use and which allows quick blade changes, making it a convenient solution for any manufacturing environment. Without any need to turn the work piece or to stop the spindle, it removes the burrs and chamfers the edges. The SNAP tool has been designed for automatic operation involving large production lots.
- Front and back chamfering of bore edges in One Operation.
- Manually exchangeable carbide blade with material-specific coating.
- The compact design ensures easy handling and high process reliability.
- No injury of bore surfaces during penetration of the bore.
- Can be used for bore diameters of 2.0 mm and larger.
The SNAP chamfering blade is held by a spring-loaded control bolt inside the tool body so that it can move. The specially ground SNAP blade for front and back or only back cutting generates the desired chamfer by forward feed. As soon as the defined chamfer thickness has been achieved, the SNAP blade radially enters the tool body. The chamfer thickness and angle are geometrically defined on the SNAP blade and can only be modified by inserting a SNAP blade with different specifications. When it exits the bore, the SNAP blade returns to its home position via the spring-loaded control bolt. A specially designed sliding section prevents the bore from being injured. It is also possible to penetrate reamed bores without risk of damage. The result is exceptional front and back chamfering in One Operation.
The operation is very simple. The tool blade is moved by rapid motion to a point ahead of the top bore edge. The top bore edge is machined by forward feed and with the working RPM. When the chamfer thickness has been achieved, the SNAP blade automatically enters the tool body. Now the tool moves by rapid motion and without stopping the spindle through the bore until the SNAP blade has again been extended at the back of the work piece. Now the back bore edge is chamfered by backward feed. When the chamfer has been produced, the tool moves out of the bore again by rapid motion.

The tool assortment is comprised of tools for bore diameters of 2 mm to 35 mm. Cassettes allow bore diameters of any size to be processed. The chamfer thickness is 0.1 mm to 1.5 mm, depending on the blade selected. Within the tool series, diameter versions are available which cover a minimum bore diameter. For details, please see the technical documentation.
