Milwaukee Tool 48-32-4807 SHOCKWAVE, Impact Duty 6" Phillips #2 Power Bits Bulk 10

Both. The Shockwave Impact Duty bits are built for impact drivers as well as standard drill drivers. The Shockzone shank is engineered to flex and absorb peak torque instead of snapping, and the shank geometry is tuned per tip type, which is what separates an impact-rated bit from a plain insert bit that shears off under hammering.

The 48-32-4807 will not fit a hex head fastener; it is a Phillips #2 power bit. For hex washer-head screws, the Rack-A-Tiers 70462RY is a 2 inch hexagonal magnetic driver bit in the C-Rhex series, and its magnet holds the screw in place while you start it. Keep the Milwaukee Phillips #2 bits for cross-recess screws, where the 6 inch length gets the driver out past framing and into recessed holes.

They drive different fastener heads and reach different depths. The Milwaukee 48-32-4807 is a 6 inch Phillips #2 power bit, sold in a bulk 10 pack, made from a proprietary steel and designed for impact drivers and drill drivers. The Rack-A-Tiers 70462RY is a 2 inch hexagonal magnetic driver bit in the C-Rhex series, so it seats hex-head fasteners and the magnet holds the fastener on the bit. Use the Phillips #2 for cross-recess screws where you need extra reach past a recessed or obstructed fastener, and the hex driver for hex washer-head screws such as sheet metal and panel fasteners.

Ten bits per pack. The 48-32-4807 is sold as a bulk 10-count of 6 inch Phillips #2 power bits, which is the pack trade crews buy when they are burning through #2 bits on screw guns daily rather than replacing them one at a time.

Yes. Shockwave power bits use the standard 1/4 inch hex drive, so they drop straight into any quick-change impact driver collet or a 1/4 inch hex bit holder, and into a three-jaw drill chuck as well.

Tip geometry and fit are what drive that. The Shockwave #2 uses a customized tip geometry with a Wear Guard tip and a custom heat treat, aimed at reducing stripping and keeping the tip engaged in the recess longer. Worn tips are the usual cause of cam-out, so a 10-pack lets you swap out a rounded bit rather than keep fighting it.

The 48-32-4807 is a plain 6 inch Phillips #2 power bit, not a magnetic nut driver. If you need the screw to stay put on the tip overhead or one-handed, run it in a magnetic bit holder or pick up a magnetic driver instead, such as the Rack-A-Tiers 70462RY, a 2 inch hexagonal magnetic driver bit in the Malco C-Rhex line for hex head screws.

Only where the fastener is accessible and the recess matches. A 2 inch bit such as the Rack-A-Tiers 70462RY hexagonal magnetic driver bit keeps the tip close to the chuck, which suits tight overhead or sidewall work, but it is a hex driver rather than a Phillips. The Milwaukee 48-32-4807 is a 6 inch Phillips #2, so it is the one to reach a screw at the bottom of a deep hole or past a flange, and its shank is built to absorb peak torque from an impact driver. Match the bit tip to the fastener head first, then pick the length the opening allows.

Each bit is laser etched with its size, so the #2 marking stays readable instead of wearing off like printed ink. Handy when you are carrying several sizes loose in a bag.

Proprietary steel with a custom heat treat is what Milwaukee specifies for these bits, with the hardness profile tuned so the shank can absorb torque spikes while the tip stays hard enough to resist wear.
