AirCraft Air Die Grinder Service Kit – Collet Fixing Comp. (27-29/31) For AT0007 (AT0007-SK07)
At a Glance: Collet fixing component kit for AirCraft AT0007 1/4" die grinder – renews the collet and retaining parts for secure accessory grip and smoother, safer operation.
If your die grinder accessories slip, don’t seat properly, or you notice extra run-out (wobble), the culprit is often a worn collet or damaged fixing parts. A strong, accurate collet setup is what keeps burrs, stones and cutters locked in place—especially at high RPM. The AirCraft AT0007-SK07 service kit replaces the collet fixing components for the AirCraft AT0007 1/4" air die grinder, covering reference positions 27 to 29 and 31. It’s the right refresh for restoring proper clamping force, reducing vibration, and keeping your tooling secure and true.
A worn collet or retainer can’t clamp evenly, which leads to slipping, wobble, and poor finish quality. Replacing these parts improves concentricity and helps protect both the accessory and the tool.
