Longshank Burrs are defined as those tools that have a shank length longer than
standard. This is 38mm long for a 3mm dia shank and 45mm long for a 6mm dia
shank.

The requirement of these tools is usually to access difficult areas, deep into a
component,and burrs have been made on shanks up to 300mm in length.
Unfortunately these tools suffer from a phenomena known as whirling and in order
that they can be used safely, the normal operating speeds must be reduced, often
dramatically,to avoid tool damage and personal injury.

A leaflet, which explains whirling, is now available in the pdf format for
downloading, or can be sent via email , on request. It covers the subject in
some detail and as well as identifying general Do's & Don'ts, it shows
recommended speeds for most of the current Morrisflex Longshank range.

The golden rule is to always have the largest diameter shank of the shortest
possible length. To initiate viewing/ download click on the link below: Manual For Longshank
