e) Key can also be used on the Jacobs No.35B
f) equivalent key to ROH68006 for ROHM chucks with 5/16" or 8mm pilot holes.
Don't ruin the teeth of the chuck sleeve by using a worn chuck key.
The Spigot Diameter is 5/16"(original Standard), or approx 8.0 mm
and weighs approximately 70 gms.
Note : These chuck keys can't be used on the Jacobs No.32 or No.33 chuck which requires another key.
Pending the closure of my business on retirement I am disposing of these chuck keys which are new "old stock" having never been issued from stores. The photographs form the main part of the description but some dimensional details are as listed above.
A single Chuck Key is available on another of my eBay listings.
I only post (at the actual Royal Mail cost) to Postal Codes within the UK.
