HexTap VX impact tap bit with 11 mm hex shank – M 20 x 2.5

• Thread cutting with an impact wrench via the matching Adapter 3/4" x 11 mm.
• For general use in easily machinable materials up to 900 N/mm².
• For unalloyed and low-alloy materials.
• Chamfer form B (spiral point) for through holes.
• For use in steel construction, mechanical engineering, assembly and maintenance.

Note Prepare the core hole with a diameter of 17.5 mm and position the tap straight in line with the hole axis.

• Thread cutting directly with the impact wrench – fast and powerful.
• 11 mm hexagon drive for a secure connection via the adapter.
• Ground from solid HSS-E.
• TiAlN coating for increased service life and better cutting results.
• Uniform 11 mm drive from M 8 to M 30: one adapter per impact wrench size is all you need.

Limitations

• Designed for through holes, not for blind holes.
• Not intended for high-alloy or difficult-to-machine materials above 900 N/mm².

1. Drill the core hole with a diameter of 17.5 mm.
2. Push the Adapter 3/4" x 11 mm fully onto the drive of the impact wrench.
3. Insert the HexTap VX with its 11 mm hexagon into the adapter as far as it will go.
4. Apply a suitable cutting fluid, for example VÖLKEL Cutting Oil N3S.
5. Position the tap at a right angle and cut the thread through the workpiece with controlled force.
6. Switch to reverse, back the tap out and remove the chips.
7. Check the thread with a screw or a thread gauge.
