The Milwaukee 1/2" X 13/16" Short Stop Bit SDS-PLUS, Model 48-20-7652, is a specialty masonry drill bit made for drilling precise holes for drop-in anchors. This is a stop bit designed for repeatable anchor hole drilling in concrete. If you need accurate depth control without stopping to measure every hole, this bit is built for exactly that job.

What sets this bit apart from a standard hammer drill bit is the stopping shoulder built into the body. That shoulder helps control drilling depth so you can produce fast, accurate, repeatable holes for anchor installation. On a job where you are setting multiple drop-in anchors, that saves time and cuts down on inconsistent holes that can slow the work down.

Milwaukee also uses a centering tip to reduce bit walking at the start of the hole. That matters when you need exact spot drilling, especially on finished layouts where being off by a little still means doing the work twice. The carbide cutting head is there for concrete drilling durability, while the flute design is there to move dust out quickly so the bit can keep cutting instead of packing up.

The patented flute geometry is worth calling out because it does more than just clear debris. Milwaukee states it is designed to remove debris rapidly while maximizing impact energy. In plain terms, the bit is built so the hammer action is doing useful work at the tip instead of getting wasted when dust starts clogging the hole. For repetitive anchor work, that is the kind of detail that makes a specialty bit earn its keep.

The short overall design is another practical advantage. With an overall bit length of 4-1/4 inches and a useable length of 13/16 inch, this is clearly aimed at shallow, controlled drilling rather than deep-hole work. That makes it a good fit when the goal is the correct anchor depth, not extra reach you do not need.

On the tool side, this bit uses an SDS-Plus shank, so it is intended for SDS-Plus rotary hammers that accept that interface. It is sold as an individual bit, not a set, and Milwaukee specifically positions it for use with drop-in anchors. As always with anchor work, matching the bit to the anchor manufacturer's requirements matters, and Milwaukee notes that you should follow the anchor manufacturer's guide for correct stop bit selection.

Who should buy it? Concrete contractors, electrical installers, mechanical trades, maintenance crews, and general contractors doing repeated anchor installs in concrete will get the most out of it. If you are just drilling occasional general-purpose masonry holes, a standard SDS-Plus masonry bit may be the better buy. But if your work depends on fast, consistent anchor holes, this stop bit is the right tool for the task.

Milwaukee 1/2" X 13/16" Short Stop Bit SDS-PLUS for Fast, Consistent Anchor Holes

This is the kind of specialty bit that makes perfect sense when your day involves repeated drop-in anchor installs in concrete.

• Who it's for: Pros drilling repeated anchor holes in concrete with an SDS-Plus rotary hammer.
• Why it stands out: The stop shoulder, centering tip, and debris-clearing flute design all work toward one goal: faster, more consistent anchor prep.
• Worth knowing: This is a purpose-built single bit, not a general masonry set piece. If you do not need controlled stop depth for anchors, a standard SDS-Plus bit may be the better fit.

• What is this bit designed for? It is designed for drilling holes for drop-in anchors in concrete.
• What shank does it use? It uses an SDS-Plus shank for compatible rotary hammers.
• What is the bit diameter? The bit diameter is 1/2 inch.
• Is this a set or a single bit? It is sold as an individual bit and includes one piece.
