Milwaukee 48-32-4440 – Frequently Asked Questions

1) What bits come in the Milwaukee 48-32-4440 ECX5 set?
Two 1-inch ECX insert bits, a #1 and a #2. That is the whole kit, no holder or case tips beyond the two bits. The pair covers the two ECX sizes you hit most often on electrical devices, so it works as a restock pack rather than a full multi-bit set.
2) Will 1-inch insert bits fit my impact driver, or do I need a bit holder?
Insert bits at 1 inch are not meant to chuck straight into most impact drivers reliably on their own. They are sized to drop into insert-bit holders, quick-change chucks, and multi-bit driver systems, which is how the 48-32-4440 bits are intended to be used. If you want a tip that goes directly into the driver, you want a power bit (2 inch or longer) instead.
3) Are these bits rated for an impact driver or just a drill/driver?
Impact duty. The SHOCKWAVE ECX5 bits are built for the repeated high-torque hammering an impact driver puts out, which is where standard-duty bits snap or round over. They work fine in a standard drill/driver too, but the construction is there for impact use.
4) What is an ECX bit and why would an electrician need one instead of a Phillips?
ECX is a combination tip profile used on electrical devices and panel screws, so one bit engages slotted, Phillips, and square-style recesses on device terminals. For an electrician trimming out receptacles, switches, and panel covers, it cuts the bit swapping. The 48-32-4440 set gives you the #1 and #2 ECX sizes in 1-inch insert length.
5) I'm restocking a crew's driver kits. Is the 48-32-4440 the right pack or do I need a full bit set?
For restocking, the two-piece 48-32-4440 is the focused option: it replaces just the #1 and #2 ECX tips, the two that wear out first, without paying for a full multi-bit assortment. If the crews are driving a wider range of fastener heads, a broader SHOCKWAVE assortment makes more sense and this pack becomes a top-up item.
6) What is the exact Milwaukee part number for the 2-piece ECX5 insert bit set?
Milwaukee 48-32-4440. That MPN covers the single configuration sold: the 2-piece, 1-inch SHOCKWAVE ECX5 insert bit set with a #1 and a #2 bit. There are no size or finish variations to pick between.
