Keyfit Tools Ground Anchor Speed Staker 1/2" Drill Adapter — Solid Steel for Spiral Anchors, Tree & Tent Stakes

Keyfit Tools Ground Anchor Speed Staker is a solid-steel drill adapter that lets you install heavy-duty spiral ground anchors, tree anchors, dog ties and screw-in tent stakes quickly using any 1/2" cordless drill.

When you need a faster, safer way to set large spiral anchors or stakes into soil, this purpose-built tool converts a standard 1/2" cordless drill into a high-torque anchor driver. Ruggedly machined from solid steel, the Speed Staker delivers leverage, bite and control so you avoid bending rods, wasting time, or wrestling with a manual brace. The unit is compatible with most heavy anchors and provides multiple engagement slots to fit different anchor loop styles and stake sizes. Note: anchors and stakes are not included, and this tool is not intended for use with 3/8" drills.

How does the Speed Staker make driving spiral anchors easier?

Instead of twisting anchors by hand or with pliers, the Speed Staker mounts to a 1/2" cordless drill and transfers the drill’s torque to the anchor through a targeted slot. That reduces physical strain and speeds installation while keeping the anchor aligned as it threads into the ground.

• Non-slip 7/16" hex arbor fits 1/2" drill chucks for secure power transfer.
• Closed-box and T-slot options hold small anchor loops without slipping.
• Open slot accepts larger stake heads and wider anchor rings.
• Solid-steel construction resists bending under heavy torque.

Which anchors and stakes will this adapter work with?

The Speed Staker is designed for multi-purpose anchoring hardware—spiral ground anchors, tree anchors, dog tie stakes and screw-in tent stakes. It is versatile where anchors feature U-shaped rings, loops or conventional stake heads that fit the tool’s slots.

• Fits common spiral ground anchors with small looped tops (use T-slot or closed box).
• Accepts larger screw-in tent stakes and tree anchors via the open box slot.
• Not a universal replacement for every stake—verify loop size and head shape before use.
• Anchors and stakes sold separately; tool only included.

Will this work with my drill and how do I use it safely?

Use only with 1/2" cordless drills; the Speed Staker’s 7/16" hex arbor is sized for a secure fit. Do not use with 3/8" drills. For safe operation, secure the anchor, start at low speed to seat the anchor, and maintain control as torque builds.

• Designed specifically for 1/2" drill chucks—ensure a tight chuck before starting.
• Begin at low RPM to prevent misalignment, then increase speed as anchor bites.
• Wear eye and hand protection and keep bystanders clear of the workspace.
• Use the closed box or T-slot for better control with small loops.

Who is this for? The Keyfit Tools Speed Staker is aimed at landscapers, arborists, pet owners installing secure outdoor tie-outs, camping enthusiasts who set heavy tent stakes, and homeowners preparing property for high winds. If you regularly install spiral anchors or heavy screw-in stakes and want to cut installation time while protecting your anchors and body from excessive force, this adapter streamlines the job. It’s durable enough for repeated professional use while remaining simple for DIYers who own a compatible 1/2" cordless drill.
