Milwaukee Tool 48-32-1700 SHOCKWAVE™ 20-Piece Insert Bit Set

A magnetic drive guide is included in the 48-32-1700 set, so you can go straight from the case to the driver with nothing else to order. The guide holds the screw on the bit for one-handed starts overhead or in a panel, and it snaps into the case cover so it does not end up loose in the bottom of the bag.

S2 tool steel. That is the shank material Milwaukee uses across the SHOCKWAVE 20-piece insert bit set, which matters if you are driving with an impact driver rather than a drill, since impact drivers hammer the bit rather than just turning it.

Insert bits are the short one-inch style with a 1/4 inch hex shank, so they drop into a 1/4 inch hex chuck on an impact driver or into a holder. The magnetic drive guide supplied with the 48-32-1700 set is what you want when you need the screw to stay put on the bit; for straight driving, the bit goes in the tool on its own. Power bits (the longer two-inch style) are the alternative if you want reach without a holder.

One configuration, ordered as 48-32-1700. There is no finish, size, or length choice to make on it; the set ships as the 20-piece assortment with the drive guide and case. For MRO or facilities buyers standardizing driver kits across techs, that means a single part number to reorder against.

Each bit has its own marked slot in the case, so sizes are identified rather than dumped in a tray. The case itself is magnetic, which is the difference that shows up on a ladder or in a lift: it sticks to the strut or the panel instead of sliding off. For a crew sharing bits across a job, individual storage is also what tells you at a glance which size has walked off.
