The Strong Arm 5HD is a convenient and powerful solution to many common issues when drilling with a portable hand drill. The design of the Strong Arm multiplies normal drilling force by 75% and can be used to push or pull, making drilling holes in heavy material much easier. This system is also much safer for overhead drilling - allowing the user to stand to the side, instead of directly under hot, sharp falling filings. Its combination of power, light weight, and convenience allows the operator to perform otherwise tough drilling situations and keeps the operator from risking injury and feeling fatigued. The Strong Arm 5HD fits most drills that use a clamp-on anti-torque handle. (See Documentation tab for specifics) Other drills, as well as air drills, can be used with the optional Drill Chuck Adapter. Warranty: 1 year manufacturer's warranty
