I was looking at the shockwave with the reduced shanks.....and got me thinking.....or not.

For those that use the 1/4 bits with the reduced shank, what are the pros of it ?

For driving home fasteners, it's usually me using up a large stash of roberstons in 2-3 inchs lengths, and or Wiha terminators torx or some Wera torx in extended lengths as well.

The reduced thinner shank - when I see them seem so -foreign- to me, since I'm just OLD, and accustomed to seeing a solid shank.

I can see how it would be good for shallow phillips......pfft. Don't use that ****.

Only PH I use is for the sheetrock guns, and that's the very reason why - cause it cams out so easily....

The "ShockZone" relief shank is supposed to be optimized to asorb peak torque and reduce breakage.

My best layman's understanding its designed to twist some (but not deform) where as a more rigid solid shank would possibly just fracture :dunno: Does seems counterintuitive in a way that thinner is possibly stronger :eyecrazy:

I'm not positive but thinking other brands besides Milwaukee may offer a similar relieve shank design now too.

A shallow head Phillips will usually have a thin washer head.

Sprint care drive shafts are necked down in the middle. I was told that was the reason. Makes perfect sense really.

I think we're talking about two different things here. I thought this thread was about reduced diameter Phillips 1/4 inch insert bits.

I've picked up some of the Bosch Impact Tough stuff from Lowe's.

It should act as a damper effect, in theory.

I don't think I care, as long as that's not the part that breaks. And frankly, in front of an M18 Surge driver, I doubt it ever will be.

Saw some dude with the Red Bit on his impact. Man, everytime I see said reduced shank bits, it makes me do a doubletake....wonder how long those things last..and or how much flex is there, when you're driving in a large diameter/long structural grade screw

I have to say my "long" Milwaukee Shockwave bit holder sure looks weirdly :eyecrazy: with it's reduced shank
