Drill Chucks
Wescon makes two kinds of drill chucks and collets for aircraft drill motors. WES1605 threaded drill collets screw onto a 1/4-28 angle drill and hold a straight shank drill bit on a 120 degree seat, in wire gauge, letter and fractional sizes from #50 to F. The WES1750 and WES1760 quick change drill chucks mount on a 3/8-24 or 1/2-20 spindle and take WES1615 and WES1625 quick change collets, so a drill changes without a chuck key. Made in USA.
Threaded drill collets with 1/4-28 male thread and 120 degree seat for 1/4-28 threaded angle drills and pancake drill attachments. Hold round shank bits and cutters from #50 (0.070 in) to F (0.257 in). Custom sizes on request.

Wescon USA’s drill chucks and quick-change adapters give aerospace mechanics fast tool changes without losing concentricity.
Built for heavy-duty aircraft assembly lines, our Quick-Change Chucks (including the WES1750 and WES1760 series) are drop-in replacements for legacy Magnavon tooling. Our pull-collar quick-release systems are compatible with industry-standard Boeing quick-change drill bits, so mechanics can use the tooling and surplus bits their assembly floors already stock.
Made in USA, our drill chucks mount to standard and right-angle pneumatic drill motors. For tight-clearance operations, our short-series collet chucks feature a 120-degree seating angle and 1/4"-28 male threads, allowing the use of standard aircraft drill bits in tight spots on the airframe.
- Boeing Quick-Change Compatibility: Accepts standard aerospace quick-change bits and reamers, compatible with legacy Magnavon tooling.
- Fast Tool Changes: Minimize downtime and skip chuck keys with our pull-collar release.
- Close-Quarter Capability: Short-series designs (like our WES1615) and 120-degree seating angles suit tight spots on the airframe and right-angle drills.
- High-Precision Concentricity: Machined to minimize wobble and runout, so holes stay within mil-spec and commercial aerospace tolerances.
- In-House Production: Every chuck is made under one roof, so we control quality and lead times.
- Fast, Global Shipping: In-stock chucks ordered by 12 PM CST ship the same day, worldwide.
