Milwaukee 48-32-4607 – Product Description
The 48-32-4607 is a Milwaukee SHOCKWAVE™ Impact Duty 2" Square Recess #3 (SQ3) Driver Bit – 5 pack.
What it is:
A set of five 2-inch SQ3 (Robertson #3) square-drive impact-rated bits, used with impact drivers or drill drivers via a bit holder or extension.
Key features:
-
Type: Square Recess #3 (SQ3 / Robertson #3)
-
Length: 2 inches
-
Quantity: 5 bits per pack
-
Material: Milwaukee Custom Alloy76™ steel
-
SHOCKWAVE™ design: Built for impact drivers and high-torque fastening
-
Shockzone™ geometry: Absorbs peak torque to reduce breakage and extend bit life
-
Wear Guard™ tip: Helps maintain fit and reduces wear over time
-
Precision-machined tip: Improves grip and reduces stripping

In plain terms:
This is basically the same “workhorse” square-drive bit size as SQ2, but one size larger (SQ3) for heavier-duty screws used in structural work like framing, timber construction, and industrial fastening where higher torque is needed.
Simple takeaway:
- SQ2 = very common general construction square drive
- SQ3 = larger, heavier-duty version for bigger screws and higher torque applications
