The high spindle speed of 910 RPM delivers fast drilling action, helping users complete projects efficiently.

STIHL’s advanced anti-vibration system reduces vibration transferred to the operator, improving comfort and control during prolonged use. Combined with ergonomic controls, a primer bulb, and throttle lock for easy starting, the BT 45 is designed to make drilling tasks faster, safer, and less physically demanding.
