Game changer
Wow. I have had these for about 6months never used them. Had a job were one of the carrier bolts had broken in the rear end. Dilled for about 40 seconds and the whole bolt just backed out. Most times you drill then drill a bigger hole tap, it out or just keep drilling till there is no more bolt left. A true time saver will be buying more bits from this company. Keep up the great work

Really sweet kit, made in the USA.
Nice box, like an ammo can. Broke a small bit, they replaced it quickly. No problems. Shipped way more quickly than amazon said it would. Very nice, sharp bits. Cut into a well hard zinc automotive bolt and extracted it.

Quality. If you need this, you don't want sub-prime; you want to get out of a jam.

Sharp as the day is long
Don't waste these on regular jobs they are for getting out broken screws. Best damn bits I've ever used and these are left handed. Have used 3 sizes at least 10 times and still sharp. Just remember to go slow and let the drill do the work. Use plenty of cutting oil and keep perpendicular to the broken bolt. Says they are guaranteed for life. Can't say the same for anyone who borrows these from me.
