PFERD Rigid extension SPV 150-1/4 S3/8 89912006

Extensions for drive spindles are used to extend the shafts of grinding and milling tools. They enable use in hard-to-reach places and are clamped into the collet of the machine (compressed air or electric drive) or into the handpiece of the flexible shaft.Extensions for drive spindles are an economical alternative to custom-made milling and grinding pins with long shafts.Safety note: Attention! When using spindle extensions, the applicable safety regulations and accident prevention regulations must be observed.When working with long shaft lengths, it is imperative that the tool is inserted into the workpiece (e.g. holes, pipes, channels or grooves) before switching on the drive machine. Under no circumstances must the extension run freely with the tool outside the workpiece.Failure to do so increases the risk of accidents! Under unfavorable conditions, there is a risk of the extension bending with the tool clamped in. The extension is only suitable for hand use in conjunction with suitable pneumatic or electric drives or flexible shaft handpieces for tools with standard shafts. It is inserted into the impact-free collet of the device in conjunction with a tool approved for the speed. Under no circumstances may it be clamped on the transition radius. Clamping a second extension or tools with overly long shafts is prohibited.
