Our take on the Milwaukee 2730-21 Circular Saw Kit, 18 V Battery, Lithium-Ion Battery, 6-1/2 in Dia Blade, Black/Red

The Milwaukee 2730-21 is an 18V brushless 6-1/2 in. cordless circular saw kit built for framing, decking and trim work. It ships with a 5.0Ah REDLITHIUM battery, a charger and a case, and Milwaukee claims faster cutting, longer run time and longer motor life than competitive 18V saws. A cast magnesium shoe, rafter hook and LED light make it a job-site tool rather than a homeowner one. Against 7-1/4 in. corded saws it trades depth of cut for portability; against other 18V saws it is one of the strongest cutters in its class.

Pros
  • Brushless POWERSTATE motor with strong cutting power for an 18V saw
  • 5.0Ah REDLITHIUM battery gives long run time per charge
  • Cast magnesium shoe keeps it light and rigid
  • Integrated LED light and rafter hook for job-site use
  • REDLINK PLUS protection against overload and overheating
Cons
  • 6-1/2 in. blade limits depth of cut versus 7-1/4 in. saws
  • Kit weight with the 5.0Ah battery is noticeable overhead
  • Blade is on the left, which some right-handed users dislike
  • Premium tool built for pros, not occasional DIY use

About the Milwaukee 2730-21 Circular Saw Kit, 18 V Battery, Lithium-Ion Battery, 6-1/2 in Dia Blade, Black/Red

The Milwaukee M18 FUEL 2730-21 is a cordless 6-1/2 in. circular saw kit powered by an 18-volt lithium-ion battery. It uses a POWERSTATE brushless motor, which is made to deliver cutting power for jobs that previously called for a corded tool. The kit includes a REDLITHIUM XC 5.0 Extended Capacity battery pack.

The REDLINK PLUS intelligence system protects the tool from overloading, overheating and over-discharging while keeping performance optimized. The saw has a cast magnesium shoe and upper and lower guards, which make a durable, lightweight base. An integrated LED light lights the cut, and a rafter hook lets you hang the saw for storage on the job.

Questions and answers

How deep can the 2730-21 cut?
With its 6-1/2 in. blade it cuts about 2-1/4 in. deep at 90 degrees, enough for 2x lumber. It will not cut through 4x material in one pass like a 7-1/4 in. saw.
What comes in the kit?
The kit includes the saw, one 5.0Ah REDLITHIUM battery, a charger and a carrying case.
Does it use the same batteries as other Milwaukee tools?
Yes. It runs on Milwaukee's M18 batteries, so it shares packs with the rest of the M18 lineup.
Is it better than a corded circular saw?
It matches corded saws on most framing and trim cuts and frees you from an outlet. A corded 7-1/4 in. saw still wins on deep cuts and continuous heavy use.
Is the blade on the left or right?
The blade is on the left side of the tool, which gives a clear view of the cut line for right-handed users.
Can it cut metal or masonry?
It is a wood-cutting saw. With the right blade some light metal cutting is possible, but masonry needs a different tool.
