Product details
The WESKIT007 Microstop-Countersink Kit pairs our heavy-duty WES596-S microstop with eight piloted countersink cutters for airframe depth control. The cage adjusts in 0.0005" steps and holds the set depth through continuous countersinking, so fasteners sit flush with the aircraft skin.
By pairing our heavy-duty microstop cage with an 8-piece set of precision HSS 100° countersink cutters, production engineers can achieve repeatable results across a wide range of hole diameters. This combination provides the rigid stability needed to reduce tool chatter and surface deformation. Whether used on aluminum alloys or light composite stacks, this kit delivers the precision and durability needed on the assembly line.
Precise Depth Repeatability: The WES596-S cage offers micro-adjustable depth control for consistent, flush fastener seating across thousands of holes.
Comprehensive Cutter Range: Includes eight specialized HSS cutters, covering common aerospace sizes from #40 pilot holes to 1/4" structural fasteners.
Wescon Durability: Made in the USA for continuous assembly line use.
