Schroeder Spiral Ratchet Screwdrivers

Schroeder Spiral Ratchet Screwdrivers

Based on Stanley's Yankee-type screwdrivers, these are the original portable power drivers. A simple push operates these drivers in forward or reverse, and you can lock the clutch for high-torque manual driving as well. Schroeder's Spiral Ratchet screwdrivers have a durable chrome finish and painted wood handles. When you're not using you spiral ratchet screwdriver you can lock it in the closed position to save space in your toolbox.

Type

We offer two types of spiral ratchet screwdrivers from Robert Schröder of Germany.

• The Standard or Yankee-type driver uses traditional round shank bits with locking grooves like have been used in spiral ratchet drivers for many years.
• The compact size uses 5.5mm (7/32") diameter bits.
  It includes three driver bits: one 4.5mm slotted, one 5.5mm slotted & one Philips #1.
• The Hex-type driver uses standard, widely available 1/4" hex drive bits - more convenient, but less traditional. It has a threaded knurled locking ring to secure the bits in place so they don't come out on the return stroke. Hex drivers include three double ended driver bits: one 4.5mm slotted + Philips #1, one 5.5mm slotted + Philips #2 & one 7mm slotted + Philips #3.

Made in Germany

We offer a selection of replacement Yankee-type driver bits to fit these drivers. (And a few to fit the now-discontinued large version.)
