Milwaukee M18 FUEL Hackzall vs Milwaukee M18 Fuel 6.5-Inch Circular Saw

These are different tools, not rivals. The Hackzall is a one-handed reciprocating saw for cutting metal, pipe and embedded material; the M18 FUEL 6.5-inch circular saw is for straight cuts in lumber and sheet goods. Buy the Hackzall if you cut in tight spots or overhead; buy the circular saw if you frame, deck or rip plywood. Both share the M18 battery platform, brushless POWERSTATE motors and REDLINK PLUS protection, and owners rate both lines for durability.

  • Choose the Milwaukee M18 FUEL Hackzall if you need one-handed cutting in tight spaces, overhead work, or through metal, pipe and demolition material.
  • Choose the Milwaukee M18 FUEL 6.5-inch circular saw if your work is straight cuts in lumber, plywood, decking and framing.

What reviewers say

Milwaukee M18 FUEL Hackzall

Owners rate the Hackzall highly as a one-handed saw for pipe and conduit, and most praise the brushless power and compact size. The common complaints are that it is sold bare and that it is slower than a full-size reciprocating saw on heavy material.

What people mention
  • One-handed usePraisedOwners say the compact grip makes overhead pipe and conduit cuts easy.
  • PowerPraisedReviewers find the brushless motor strong for a saw this size.
  • Bare toolCriticisedBuyers note the tool alone does not include a battery or charger.
  • Cutting speedMixedIt cuts metal and pipe well but is slower than a full-size Sawzall in thick wood.

Milwaukee M18 Fuel 6.5-Inch Circular Saw

Owners and reviewers rate the M18 Fuel 6.5-inch saw as one of the strongest 18-volt cordless circular saws, with power close to corded models and durable build. Complaints center on the bare-tool packaging, weight with a big battery and the smaller blade's depth limit.

What people mention
  • PowerPraisedOwners say it cuts 2x material without bogging down, close to corded performance.
  • BuildPraisedReviewers describe the shoe and housing as sturdy and jobsite-durable.
  • BatteryMixedRuntime on XC5.0 packs is praised, but the bare-tool package means buying batteries separately.
  • WeightCriticisedSome owners find it heavy once a large battery is mounted.

Questions and answers

Which is better for cutting metal pipe?
The Hackzall. Its reciprocating blade and 7/8-inch stroke cut pipe, conduit and threaded rod; a circular saw is not made for metal.
Which is better for framing a deck?
The circular saw. It makes fast, straight crosscuts and rips in lumber and decking, which the Hackzall cannot do cleanly.
Do both use the same batteries?
Yes. Both run on Milwaukee M18 packs, so one battery set covers both tools. Note that both are commonly sold as bare tools.
Which lasts longer?
Both use brushless POWERSTATE motors and REDLINK PLUS protection. Milwaukee claims up to 3X longer tool life for the circular saw; the Hackzall's counterbalance reduces wear from vibration. Real life depends on blades and load.
Is the circular saw worth stepping up to if I already own the Hackzall?
Yes if you cut lumber. The Hackzall handles demolition and metal, but straight, splinter-free cuts in wood need a circular saw.
Can the Hackzall replace a circular saw?
No. It cuts curves and flush cuts well, but its reciprocating action leaves rough edges and cannot make long straight rips.
