Question 1

What is the Milwaukee 48-20-7490 SDS Plus M/2 Kit designed for?

Accepted Answer

The Milwaukee 48-20-7490 is a 5-piece SDS Plus M/2 2-Cutter drill bit kit designed for general concrete drilling. It is suitable for use with corded and cordless rotary hammers and is engineered for demanding construction applications where durable concrete drilling performance is required.

Question 2

Can these SDS Plus bits drill through rebar?

Accepted Answer

The M/2 2-Cutter drill bits feature enhanced rebar guards designed to increase durability in hard aggregate and rebar applications. The rebar guards help protect the bit during demanding drilling conditions, making the kit suitable for concrete drilling environments where reinforcement may be encountered.

Question 3

How does the centering tip help during concrete drilling?

Accepted Answer

The centering tip is designed to support exact spot drilling, helping users establish accurate hole placement before the bit fully engages the material. This feature can be useful for professional construction and installation work where precise drilling locations are important.

Question 4

What makes the variable flute design useful?

Accepted Answer

The variable flute design is engineered to maximize debris extraction during drilling. Efficient removal of concrete dust and debris helps keep the hole clear while supporting consistent drilling performance. Milwaukee also states that the design can provide up to 20% more holes per charge when used in cordless rotary hammers.

Question 5

How do the wear mark indicators work on these drill bits?

Accepted Answer

The wear mark indicators help users identify when the drill bit has reached the end of its usable life and no longer meets ANSI diameter requirements. This provides a visual reference for monitoring bit wear and determining when a replacement is needed for accurate drilling applications.
