GCH850 - Cordless 2" 21 Gauge Brad Nailer

The Grex GCH850 is again, a first of its kind. The first and only cordless 21 gauge brad nailer. It touts the same size, weight and ergonomics as our cordless 23 gauge headless pinner, but with the ability to drive 21 gauge brad nails up to 2" in length; making it the most versatile cordless finish nailer in the industry. Grex Cordless technology continues to make it possible to create cordless nailers in a form factor that you need with no compromise on power. The 21 gauge brad nail is a perfect compromise providing holding power closer to that of an 18 gauge brad nail, but leaving a hole size closer to that of a 23 gauge pin. This translates into both time and cost savings by being able to go onto a jobsite with only one nailer instead of 2 different tools. Plus this is all achieved with the same award winning robust build quality that users have trusted for more than 25 years.
