Question 1

What is the Milwaukee 48-20-3916 SDS Max Drill Bit used for?

Accepted Answer

The Milwaukee 48-20-3916 SDS Max Drill Bit is designed for drilling 5/8-inch holes in concrete and masonry. Its 4-cutter carbide design and rebar guards make it suitable for reinforced concrete, hard aggregate, anchoring, doweling, and commercial construction applications where the bit may encounter rebar.

Question 2

Can the Milwaukee 48-20-3916 drill through reinforced concrete with rebar?

Accepted Answer

Yes. The bit is engineered specifically for concrete with rebar and features an integrated 4-cutter design with rebar guards. This geometry is designed to help reduce lock-up when the cutting edges encounter reinforcing steel while providing durability for demanding reinforced concrete drilling applications.

Question 3

What type of rotary hammer does the 48-20-3916 fit?

Accepted Answer

The Milwaukee 48-20-3916 uses an SDS Max shank and is designed to fit all SDS Max rotary hammers. This makes it suitable for professional concrete drilling tasks requiring an SDS Max rotary hammer platform and a 5/8-inch hole diameter.

Question 4

How does the 4-cutter design improve concrete drilling performance?

Accepted Answer

The 4-cutter geometry uses four cutting edges to support efficient drilling through concrete and reinforced concrete. The solid carbide head and sharp centering tip help provide accurate hole placement, while the cutter design is engineered to reduce lock-up when encountering rebar.

Question 5

How can I tell when the Milwaukee 48-20-3916 drill bit needs to be replaced?

Accepted Answer

The Milwaukee 48-20-3916 features wear mark indicators that provide a visual reference for bit condition. These indicators help show when the drill bit has reached the end of its usable life and no longer meets the applicable ANSI requirement, making it easier to identify when replacement is needed.
