GP SYSTEM (SINGAPORE) PTE LTD - ROHM [Product 1: KSF Stud Chucks for Collets]

KSF Stud Chucks for Collets
Drills of different length are held by the bevel and
supported axially by an adjustable stop. The projecting
length of the drill can therefore be made as short as
possible. The resulting rigidity allows high cutting rates
and increases the service life of the twist drill.
