Milwaukee 48-89-4627 15/32" SHOCKWAVE Impact Duty RED HELIX Titanium-Coated Drill Bit
The Milwaukee 48-89-4627 is a 15/32" (0.4688") SHOCKWAVE Impact Duty drill bit built with a RED HELIX flute design and a titanium-coated finish for demanding professional drilling applications. As part of Milwaukee's SHOCKWAVE Impact Duty accessory line, this bit is engineered to hold up to the high torque and repeated impacts generated by impact drivers, helping reduce bit breakage and downtime on the jobsite. The titanium coating adds wear resistance to the cutting edges, while the RED HELIX flute geometry is designed to help clear chips efficiently as the bit advances through material. Whether used for framing, remodeling, or general construction drilling, the 48-89-4627 is built to deliver consistent, repeatable holes at the 15/32" trade size.
Key Features
- Trade Size: 15/32" (0.4688") diameter delivers a precise, repeatable hole size for fastener clearance and general drilling tasks.
- SHOCKWAVE Impact Duty Engineering: Purpose-built to withstand the high torque and repeated impact forces generated by impact drivers, helping extend bit life compared to standard drill bits.

Milwaukee 48-89-4620 – Frequently Asked Questions
1) What sizes does the Milwaukee SHOCKWAVE RED HELIX titanium drill bit come in?
Two trade sizes: 23/64 inch (Milwaukee 48-89-4620) and 15/32 inch (Milwaukee 48-89-4627). The 15/32 inch measures 0.4688 inch. Both are the same SHOCKWAVE Impact Duty RED HELIX titanium-coated bit, so order by the part number that matches the hole you need.
2) Can I run the Milwaukee 48-89-4627 bit in an impact driver, or do I need a drill?
It is built for an impact driver. The 48-89-4627 is a SHOCKWAVE Impact Duty bit with an impact-ready shank for retention in impact driver chucks, and the whole line is engineered for the high torque and repeated impacts those tools generate to cut down on bit breakage.
3) Is the Lenox 12111-10DGHS diamond grit drill bit a substitute for the Milwaukee 48-89-4627 SHOCKWAVE bit?
No, they are built for different work. The Milwaukee 48-89-4627 is a 15/32 inch titanium-coated SHOCKWAVE Impact Duty twist bit with RED HELIX flutes, intended for pilot and clearance holes in wood, metal, and plastic and for use in impact drivers. The Lenox 12111-10DGHS is a 5/8 inch diamond grit bit from the D/S-10Dg series, which abrades rather than cuts with a fluted twist geometry. If you need a 15/32 inch hole in framing lumber or sheet metal, the Milwaukee bit is the correct choice; a diamond grit bit is a different tool for hard, abrasive materials.
4) What materials will the 15/32 inch SHOCKWAVE RED HELIX bit drill?
Wood, metal, and plastic, for pilot and clearance holes. Typical use is framing, remodeling, general construction drilling, and fastener prep work. If you are cutting hole saw sized openings in masonry or tile, this twist bit is the wrong tool.
5) Is 15/32 inch the right drill bit size for a 1/2 inch bolt clearance hole?
15/32 inch (0.4688 inch) is the common undersize step just below 1/2 inch, so it is used where you want a snug fastener fit rather than a loose 1/2 inch clearance hole. For a free-running 1/2 inch bolt you want a full 1/2 inch or larger bit; the 48-89-4627 at 15/32 inch will bind on a 1/2 inch shank.
6) Will a Milwaukee SHOCKWAVE titanium bit drill through concrete or hardened material?
No. The 48-89-4627 is a titanium-coated twist bit for wood, metal, and plastic. For abrasive material like tile, stone, or glass you need a different tool type, for example the Lenox 12111-10DGHS diamond grit drill bit in the D/S-10Dg series, which cuts by abrasion rather than by a cutting edge.
7) I need a 5/8 inch hole, not 15/32 inch - what should I look at instead of the Milwaukee SHOCKWAVE bit?
The Milwaukee 48-89-4627 SHOCKWAVE Impact Duty bit is a 15/32 inch (0.4688 inch) trade size, and the companion 48-89-4620 covers 23/64 inch, so neither will produce a 5/8 inch hole. For a 5/8 inch hole, the Lenox 12111-10DGHS is a 5/8 inch diamond grit bit, suited to abrasive material rather than to impact-driver drilling in wood and metal. Match the bit to both the diameter and the material you are drilling.
8) What does the titanium coating on the Milwaukee SHOCKWAVE bit actually do?
The titanium coating adds wear resistance at the cutting edges so the bit holds its edge longer through repeated holes. It is a surface coating on the bit, not a solid titanium tool, and it does not change the hole size.
9) What is the RED HELIX flute for on these Milwaukee bits?
The RED HELIX flute geometry is there to move chips up and out of the hole as the bit advances, which matters most on deeper holes in wood and in metal where packed chips stall the bit and overheat the edges.
