Removing Seized/Stuck/Frozen Seatpost With Impact Wrench

I show how to remove a stuck seat post using an impact wrench. I used a Kawasaki 840017 1/2" impact wrench that is rated for 220 ft/lbs of torque. A higher powered impact wrench probably would have done the job faster. More power is always good! The masonry drill bit I used was a Bosch 5/16 in. x 4 in. x 6 in. Blue Granite Turbo Carbide Hammer Drill Bit from Home Depot. I ran the drill press at 990rpm. Maybe a bit fast. There are not good charts for using a carbide tip masonry bit to drill hardened steel. There are different opinions on what speed to use. The 30mm impact socket came from Harbor Freight. The bolts were 5/16" grade 8 bolts. The bolts showed no wear. The holes in the seatpost were only slightly deformed. ▶ SUBSCRIBE & HIT THE 🔔 bit.ly/SubRJTheBikeGuy 👍 And please give my video a thumbs up 👍 ▶FACEBOOK.com/RJTheBikeGuy www.facebook.com/RJTheBikeGuy ▶TOOLS www.rjthebikeguy.com/tools ▶SHIRTS bit.ly/RJBikeGuyShirts ▶WEBPAGE www.RJTheBikeGuy.com/
