Description
Wera 004021 8100 SA 11 Zyklop 1/4″ Drive SAE/Imperial Ratchet Set
The Fastest Ratchet on the Planet – 5 Tools in One
The Wera 8100 SA 11 Zyklop Speed set is engineered for those who value time and mechanical precision. The heart of this 28-piece Imperial (SAE) set is the Zyklop Speed ratchet. By combining a flywheel design with a free-turning sleeve, Wera has created a tool that spins fasteners significantly faster than a conventional ratchet.
The Zyklop Speed is a true multi-tool, functioning as a Fine-Tooth Ratchet, Flex-Head Ratchet, Angle Ratchet, Quick-Release Ratchet, and a Power Screwdriver. With a 72-tooth fine-pitch mechanism, you only need a 5° return angle, making it the ultimate solution for tight engine bays and industrial maintenance.
Why the Zyklop Speed Set is a Must-Have:
- Swivelling Ratchet Head: Lock the head at 0°, 15°, or 90° for maximum leverage or to use as a high-speed screwdriver.
- Flywheel Construction: The mass-balanced design accelerates the screwdriving process.
- Press-Button Release: Guaranteed socket security; sockets will not fall off until you press the release button.
- Imperial "Take It Easy" Sockets: Color-coded by size so you grab the right socket every time.
- Durable Textile Case: Unlike bulky plastic cases, this slim, robust textile box protects your tools while taking up minimal space in your bag.

Frequently Asked Questions
+ Why is it called the "Zyklop Speed"?
The "Speed" name comes from the flywheel design and the free-turning sleeve. This allows you to "spin" the fastener in or out at high velocity once the initial torque is broken, much like a screwdriver but with the power of a ratchet.
+ Can the ratchet be used as a screwdriver?
Yes. By locking the head in the 0° position and using the bit adapter, the Zyklop Speed functions exactly like a high-torque screwdriver.
+ What sizes are included in this Imperial set?
This set includes nine sockets: 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 7/16", 1/2", and 9/16". It also includes a variety of driver bits (PH, PZ, Torx, Hex, Slotted) and two extensions.
+ Is the textile case better than a plastic box?
Wera's textile boxes are significantly more durable and lighter than traditional plastic cases. They don't crack if dropped, they won't rattle in your truck, and they feature a hook-and-loop backing for easy attachment to Wera 2go carrying systems.
