Review on 🔧 E-Z LOK 400-4-CR Threaded Inserts for Wood: Stainless Steel, Installation Kit with 1/4-20 Knife Thread Inserts, Drill, and Installation Tool by Delos Montano

I used these on river table legs to set in VERY hard hickory. 25/64 bit was VERY comfortable. In some places I had to overclock to 13/32. I've found that a 1/2" stainless steel screw works best for driving into wood. Keep the special brand tool in case you get confused and need to pull one out. Brass inserts are very prone to chipping if used too often Torque on the EZ Lok Insertion Tool but the 1/2" 1/4" 20 screw came in well. Now that I know how to use it I would buy it again.
