Stub Drill System for HSS and Carbide stub drills and special drill applications
The Bilz stub drilling system consists of the ASR drill chick used in
conjunction with a WZHR toolholder.
It is designed for use on transfer lines and special purpose machines,
the shortprojection length of the unit ensures rigidity and
accuracy and is ideal for drilling applications without the need for
bushing.
The ASR chuck is screwed directly on to the machine spindle, and
is locked in position using a micro-encapsulated adhesive wich
provides a secure bond and can be easily cracked when the chuck
is required to be removed.
The WZHR tool holder is automatically locked into the chuck and
axial play is eliminated by means of a newly developed roller
mechanism. The close manufacturing tolerances and positive drive
combine to ensure rigidity and concentricity.
The tools can be set off the machine and the internal adjusting
screw allows for easy length setting.
In addition to the WZHR having versions which accept ESX collets
and DIN 1835 shanks.
The system is suitable for both right and left hand operation, and it
can also be supplied with a coolant feed facility if required.
Special versions of this range of tooling can be supplied to order.
