Bosch GCG 18V-310 18v Cordless Brushless Caulk Gun

The Bosch GCG 18V-310 is an 18V cordless brushless caulk gun designed for professional dispensing and caulking applications using cartridges of up to 310 ml.

Precision control is central to this tool's design. Nine speed settings combined with a variable speed trigger give tradespeople accurate command over material flow, making it equally effective with light sealants and high-viscosity adhesives. A push force of 3.5 kN and a feed rate of 7 mm per second ensure consistent, fast application even with demanding materials.

The auto-reverse function is a practical feature that sets this gun apart for professional use. When the trigger is released, pressure on the plunger rod is automatically relieved, preventing dripping and material overflow — reducing waste and keeping work areas clean.

Suited to a wide range of trades, the GCG 18V-310 is a reliable choice for construction, plumbing and heating, joinery, and electrical installation work. It runs on the Bosch Professional 18V system and is also compatible with the AMPShare multi-brand battery platform, making it a versatile addition to any existing cordless toolkit.
