PULL STUDS & WRENCHES

Pull studs for tool holders

The pull stud is the critical link between the tool holder and spindle. Pull
studs must always be fully tightened into the tool holder, checked periodically
and replaced if worn or damaged. These are not certified as original
manufacturers’ products.

Wrenches for ER slotted nuts NPS115

Standard steel wrenches with moulded handgrip for ER slotted nuts.
In addition to the standard wrenches, torque wrenches are available for ER25,
ER32 and ER40 nuts. These ensure the correct torque on the nut to maximise
the clamping force on the cutter shank without overtightening, which can
damage the collet. Each wrench has two settings: one for cutter shanks from NPS118
1mm to 7mm and the other for cutter shanks over 7mm.
