These days everything ratchets: screwdrivers, box end wrenches, adjustable wrenches, hex key sets — so why not bring your old drill press or power drill into the 21st century with a ratcheting chuck key from Ratchkey? If you’ve ever pinched or skinned your fingers trying to use an original chuck key, or had problems loosening the chuck to remove a bit, you’ll appreciate Ratchkey’s design.
The ratcheting chuck key can apply up to 120 inch-pounds of torque with its highly visible, red, high-impact, polymer handle. Ratchkey designed the handle to be comfortable to hold, unlike the small steel rod on most chuck keys. The ratcheting action works in only one direction — you use one side to tighten the chuck, and the other side to release it.
Ratchkey makes their ratcheting chuck keys in four sizes:
- The HC-10 for 0 – 3/8″ drills, Jacobs KG series chuck keys.
- The HC-12 for 3/8″ – 1/2″ drills (10 mm), Jacobs KK series keys.
- The HC-14 for 1/2″ (13 mm) – 1/4″ pilot – Jacobs K-32 series.
- The HC-15 for 1/2″ (13 mm) – 6 mm pilot – Röhm style S32A chuck key.
If you don’t know what size key you need, a table on the McFEELY’s link below describes which Ratchkey key fits which chuck for each model on their web site .
Made in the USA with a lifetime warranty, each Ratchkey ratcheting chuck key runs about $5 — about the most cost-effective upgrade you can make to your keyed chuck drill.
