RUKO SCE-DIN22568-HSS-60°-Nr.12 estrattore viti

Screw extractor for removing broken screws, bolts, and studs with metric sizes M36 to M45 or imperial 1 3/8" to 1 3/4". Made from high-speed steel (HSS) with a left-hand spiral flute and a 60° cutting angle, it provides high wear resistance and reliable grip.

Advantages

High-speed steel construction ensures durability and long service life. The left-hand spiral flute bites into the broken fastener as you turn counterclockwise, providing a secure grip for extraction. The 60° angle is optimized for effective engagement with the broken screw.
