Power through tough ground with the STIHL BTA 140 Battery-Powered Earth Auger—built for professionals who demand performance, precision, and reliability on every job.

Part of the STIHL ALLPRO System, the BTA 140 drills holes up to 12 inches in diameter, making it the go-to solution for landscaping, forestry, agriculture, and construction work. Whether you're setting fence posts, planting trees, installing drainage, or laying small- to mid-size foundations, this auger delivers fast, clean results—even in rocky soil thanks to its sharp drill bits and aggressive cutting blades.

At the heart of the BTA 140 is a high-performance brushless motor engineered for long life and minimal wear. It runs smoothly with low vibration and quiet operation, so you can work comfortably without the need for hearing protection—ideal for crews working in residential or noise-sensitive areas.

Designed for one-person operation, this auger offers exceptional balance and a close-to-body drilling position, reducing fatigue and improving control throughout the day. Choose from three operating modes right on the handle-mounted control panel:

• Low speed for precise, low-kickback drilling
• High speed for tackling tough ground conditions
• Reverse for quickly freeing stuck bits

An integrated display keeps you informed, while the oversized comfort pad ensures steady, accurate handling every time you drill.

Safety and efficiency go hand in hand. If the auger binds, the STIHL QuickStop® system automatically shuts down the rotation to protect both you and the tool. Once cleared, simply restart and get right back to work.

Transport and storage are just as smart, thanks to a durable bracket system that saves space and helps shield critical components during transport.

For optimal performance, pair the BTA 140 with the STIHL AP 300.0 P battery, delivering the power and runtime professionals need to stay productive all day.

Built for daily use in demanding environments, the BTA 140—and all STIHL ALLPRO System tools—are splash-resistant and tested to IPX4 standards, so you can keep working even when the weather turns.

When productivity, comfort, and safety matter most, the STIHL BTA 140 delivers—job after job.
