Nulaužtų varžtų išsukėjai su kairiniais grąžtais komplektas 10 dalių

Left-hand drill and extractor set for removing broken bolts, studs, machined bolts or right-hand pipe fittings.
The drill bits are made of high-speed steel HSS 4241.
The extractors have a helical groove that automatically bites deeper into the screw being removed.
The set includes 5 drills and 5 extractors in the following sizes: 2mm (5/64"), 2.8mm (7/64"), 4mm (5/32"), 6.4mm (1/4"), 7.5mm (19/64")
 
Tip for removing a broken bolt:
 
Drill a hole in the broken bolt with the correct size drill bit.
Insert a suitable extractor into the hole and begin counterclockwise rotation.
The use of a rust remover, grease or oil may help to remove rusted or corroded bolts.
