Quick Change Drilling Chucks and Adaptors for drilling, reaming, and tapping tools.

The SBK quick change system is for use on drilling machines, either manual, radial or NC controlled. The system is designed to enable numerous functions to be carried out whilst utilizing a single toolholder.

The unique double ball clamping gives a positive drive and allows the precise location of the SEK adaptor in the chuck. The adaptors, which take drills, reamers, counterbores or tapping equipment, can be changed quickly without the use of additional tools, and are automatically located in the chuck. They are released by retracting the outer sleeve of the chuck axially, which then allows the adaptor to be removed with ease.

The changing of tools can take place either when the machine spindle is stopped or when running up to a maximum speed of 2,000 rpm.

The steep location taper of the unit allows a rapid tool change and the system is designed that the unit can operate in both the vertical or horizontal plane, and for left or right hand rotation.

SBK holders and SEK adaptors can be supplied with internal coolant feed on request. A custom design of this quick change system is available for fully automatic tool change units on special machines.

Not suitable for operations with radial forces such as milling for example.

ASR/WZHR - adaptable quick change drilling chucks, Toolholders.

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 short projection 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 which 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.

Over Spindle Quick Change Drilling Chucks for drilling, chamfering and counterboring tools.

These over spindle quick change drilling chucks can be fixed to the noses of machine spindles which conform to DIN 55058. They are located on the spindle by means of a special screw which locks the chuck onto the spindle nose. This screw locates in a tapped hole in the spindle, and the inner sleeve of the chuck has six holes which accommodate the positional tolerance of the tapped hole in the spindle and ensure free of play positioning.

These drilling chucks, combined with the Bilz SSM adjustable lock nuts provide a rapid and effective quick change system for adjustable adaptors and toolholders with DIN 6327 trapezoidal shanks. They can be used on multi-spindle machines, transfer lines and special purpose machines.

Tools can be changed quickly and easily, the tools are automatically locked into the unit on location of the tool into the spindle.

The tools are released by pulling forward the outer sleeve of the chuck and removing the tool from the spindle.

This quick change system ensures the safe, play-free location of tools in the spindle. Tool change is carried out when the spindle is stopped and the tools are easily handled even in restricted locations on equipment such as multi-spindle heads.
