Using the Bosch HC2062 hammer bit is easy. First, make sure it's properly inserted into your SDS-Plus chuck. When starting a hole in concrete, the centric tip will help you get going quickly. Just apply a bit of pressure and start drilling. It's 15% faster than the S4L, so you'll get the job done quicker. This bit is great for anchoring and through - hole applications in concrete. As for maintenance, keep an eye on the wear mark. Once the tip wears beyond the ANSI specification, it's time to replace the bit. Also, after each use, clean the bit to remove any debris. The improved flute design helps the bit run cooler, but don't overheat it by using it continuously for long periods without breaks. This will ensure the long - lasting performance of your bit, thanks to the optimized brazing and hardening process and the tough Bosch - made carbide tip.
