OCEANSIDE, CA. Masa Tool has expanded their Micrococnic Over-Grip collets to include a news style called a "T-Type" over-grip collet. The T-Type Over-grip collet has a longer gripping surface than the original W-type. We designed it specifically for parts like long bonescrews with wide pitch threads.
But in some cases, with longer parts, the land width "B" needs to be longer to support the workpiece properly.
Masa's new T-Type collet provides the solution for longer workpieces
Typically with over-gripping applications, a shorter land length/clamping pad length/grip length is desired because of limited space available to hold the workpiece behind the enlarged head or flange that it is reaching over. That is what our original W-type collet was optimized for.
However, with longer parts, with more surface area for clamping and gripping room, a longer land length is often required to provide more stability to support the longer length workpiece.
It may also be necessary with very wide-pitched threads, such as on bone screws, where a long land in the collet allows spanning several thread pitches instead of just one or two. This same spanning issue can occur with parts that have wide grooves.
Microconic T-Type Over-grip Collet features
If you've tried existing overgrip collets with poor/mixed results,Microconic over-grip will allow you to do things you might have thought impossible. Because of our extreme rigidity and concentricity. Our over-grip collets are better than others standard collets!
