WES1605 1/4-28 Threaded Drill Collets
14 Products
WES1605 threaded drill collets screw onto a 1/4-28 threaded angle drill motor and let it run standard straight shank drill bits. The 120 degree seat matches the spindle of most aircraft angle drills, so the collet seats square and the drill runs true.
Fourteen sizes cover wire gauge, letter and fractional drills from #50 (0.070 in) to F (0.257 in), including #40, #30, #21, #10 and 1/8 in. Pick the collet for the drill diameter you run, thread it onto the motor, insert the bit and tighten. Custom bore sizes are made to order for drills outside the stock range. Made in USA.

Wescon USA’s precision drill chucks and quick-change adapters are engineered to eliminate bottlenecks, delivering rapid tool transitions for aerospace mechanics without ever sacrificing concentricity.
Designed for seamless integration into heavy-duty aircraft assembly lines, our Quick-Change Chucks (including the WES1750 and WES1760 series) serve as direct, high-precision upgrades and drop-in replacements for legacy Magnavon tooling. Our pull-collar quick-release systems are fully compatible with industry-standard Boeing quick-change drill bits. This direct compatibility ensures that mechanics can utilize the exact tooling systems and surplus bits their assembly floors already stock.
Manufactured 100% in the USA from premium aircraft-grade materials, our drill chucks mount effortlessly to standard and right-angle pneumatic drill motors. For tight-clearance operations, our specialized short-series collet chucks feature a precise 120-degree seating angle and 1/4"-28 female threads, allowing the use of standard aircraft drill bits in restrictive airframe structures.
- Boeing Quick-Change Compatibility: Engineered to accept standard aerospace quick-change bits and reamers, matching or exceeding legacy Magnavon specifications.
- Ultra-Fast Tool Transitions: Minimize downtime and eliminate the need for chuck keys with our reliable, rapid-release pull-collar mechanisms.
- Close-Quarter Capability: Short-series designs (like our WES1615) and specialized 120-degree seating angles are perfectly tailored for restrictive airframe structures and right-angle drills.
- High-Precision Concentricity: Precision-machined to eliminate wobble and runout, ensuring every hole meets strict military and commercial aerospace tolerances.
