A-1-UTL Utility Drill

The Minnich A-1-UTL unit can drill vertically or horizontally, features a lightweight design for easy portability and requires minimal air — making it an ideal alternative to an electric hammer drill. Available in two powerful, compact models, the A-1-UTL drill works efficiently in confined spaces. Both units in the A-1-UTL lineup are available with an optional dust collection system to minimize debris on the jobsite. Special application and pattern kits are also available.
