Makita's impact GOLD torsion magnetic insert bit holder and Phillips insert bits are truly innovative and perform as described. While using my RIDGID impact driver the bit stayed in the screw head which helped prevent stripping and the bit stays in the magnetic bit holder which saves time on job not having to pull insert bit out of screw head. The torsion section of bit holder flexed when needed to prevent bounce out and bit damage. I have installed 2" to 3" screws in 2x4's and pressure treated 4x4's and single bit shows barely any wear. I am planning on purchasing other insert bit tips ( torx, square drive, #3 Phillips.)
I'd have to say out of experience that these bits are the strongest I've ever used. While repairing a squeekie subfloor in with my milwaukee 18v fuel impact driver I first used the high rated apex bits uses for aviation maintaince. Got 5-10 screws in before the tips blew out. Switched to the makita gold after that and finished the rest of 25x20 foot floor with one bit. About 250 screws later when I got to the stairs the bit finally broke. I recommend these above any other bit I've used milwaukee, Dewalt and apex bits. they have no chance standing up next to these makita gold bits.
I've used these with my impact driver on the last little project and they seem to be similar to any other bit that i have used. Magnets, hold bits. Can't say how well they last vs. any other set but for now they seem to be of good quality and workmanship.
Pros: Durable, Easy to Use, Good Size & Weight, Light Weight
