Milwaukee M18 FUEL M18 FHACO745-0C 45mm SDS-MAX Rotary & Breaking Hammer – 15.2J, ONE-KEY, AUTOSTOP, AVS & VACLINK – Body Only with Kitbox

Overview

Bring serious corded-class drilling and breaking performance to an entirely cordless setup with the Milwaukee M18 FUEL M18 FHACO745-0C 45mm SDS-MAX Rotary Hammer. Built for demanding concrete, masonry and demolition work, this professional hammer delivers an impressive 15.2 joules of impact energy, up to 2,625 blows per minute and a maximum 45mm drilling capacity in concrete.

Milwaukee combines its POWERSTATE brushless motor, REDLINK PLUS electronic intelligence and M18 REDLITHIUM battery platform to provide the power, durability and runtime required for heavy construction work without tying the operator to a mains cable.

The FHACO745 is also engineered around operator control. AUTOSTOP can shut the tool down during sudden bind-up movement, while Milwaukee's Anti-Vibration System (AVS) and anti-vibration side handle help reduce vibration exposure during prolonged drilling and chiselling.

Three operating modes cover rotary hammer drilling, hammer-only chiselling and Variolock chisel positioning, while integrated ONE-KEY provides tool tracking, inventory management and remote-locking functionality. Milwaukee also equips this generation with VACLINK wireless dust-control technology, allowing compatible extraction equipment to be activated directly from the tool.

This M18 FHACO745-0C bare-unit version is supplied in a Milwaukee Kitbox with side handle, depth gauge and grease. Battery and charger are not included. Article number 4933493445, EAN 4058546483166.

Key Features & Benefits

• Hit Harder Through Demanding Concrete – A substantial 15.2J EPTA impact energy gives the FHACO745 the striking force needed for heavy drilling and breaking applications that would normally call for a large corded SDS-MAX hammer.
• Drill Concrete up to 45mm – Its 45mm maximum concrete drilling capacity makes it suitable for large anchor holes, structural installations, service penetrations and other demanding construction work.
• Break and Chisel Without Changing Machines – Switch from rotary hammer drilling to hammer-only mode when removing concrete, chasing masonry or carrying out demolition work.
• Position Chisels Exactly Where You Need Them – Variolock lets the chisel be rotated into the most practical working position before hammering begins, improving access and control on awkward surfaces.
• Protect the Operator During Sudden Bind-Ups – Milwaukee's AUTOSTOP technology detects sharp tool movement and shuts down the hammer in a bind-up situation, helping reduce sudden rotational reaction.
• Reduce Fatigue During Long Drilling Sessions – An integrated Anti-Vibration System (AVS) helps isolate vibration from the main handles, while the supplied anti-vibration side handle provides additional vibration reduction.
• Match Performance to Different Applications – Milwaukee states that the FHACO745 offers four speed settings, allowing drilling and chiselling performance to be better matched to the material and task.
• Reach up to 347rpm for Rotary Drilling – A no-load speed range of 0–347rpm balances the torque and impact delivery required for large-diameter SDS-MAX drilling.
• Deliver up to 2,625 Blows per Minute – High-frequency hammer action works alongside the 15.2J impact mechanism to maintain productivity during drilling and breaking applications.
• Eliminate the Extension Lead – Cordless 18V M18 operation gives tradespeople greater freedom across unfinished buildings, outdoor sites and areas where mains power is not yet available.
• Use Batteries You Already Own – Milwaukee confirms compatibility with all Milwaukee M18 batteries, making the bare-unit version particularly attractive for users already invested in the platform.
• Get the Best from High-Demand M18 Batteries – Milwaukee specifies the tool at 9.7kg with an M18 FORGE 12.0Ah battery, reflecting its positioning as a high-output heavy-duty SDS-MAX machine. The battery is not supplied with this 0C version.
• Track Valuable Site Equipment – Integrated ONE-KEY provides access to Milwaukee's cloud-based tool tracking and inventory-management platform, useful for professional fleets and businesses managing multiple tools.
• Remotely Disable the Tool if Required – ONE-KEY also supports remote locking, adding another layer of tool management and security.
• Connect Extraction Without Reaching for the Vacuum – VACLINK enables compatible tools and dust extractors to communicate wirelessly so extraction can be activated directly from the hammer.
• Built Around Milwaukee FUEL Technology – The combination of POWERSTATE brushless motor technology, REDLINK PLUS electronics and REDLITHIUM battery compatibility is designed to maximise output, runtime and durability.
• Prevent Accidental Trigger Activation in Transit – A dedicated trigger safety lock provides a safer transport solution when moving the tool between jobs.
• Keep the Tool Protected Between Sites – This 0C package includes a robust Milwaukee Kitbox, providing dedicated storage for the hammer and supplied accessories.

Why Choose This Product

The Milwaukee M18 FHACO745-0C is designed for users who want the capability of a large SDS-MAX hammer without going back to mains power.

Its standout figure is the 15.2J impact energy. Combined with a 45mm concrete capacity and 2,625bpm full-load hammer action, it gives contractors a cordless option for genuinely demanding concrete drilling and breaking rather than limiting the M18 platform to lighter installation work.

Just as importantly, Milwaukee has built substantial operator-control technology around that performance. AUTOSTOP responds to sudden bind-up movement, AVS reduces vibration exposure and the additional anti-vibration side handle gives another layer of isolation during prolonged use.

The three operating modes also make it far more versatile than a dedicated demolition breaker. Contractors can drill large holes, switch to hammer-only mode for breaking, or use Variolock when a chisel needs to be positioned precisely.

For fleet users and larger contractors, ONE-KEY and VACLINK add functionality beyond raw drilling performance. Tools can be managed through Milwaukee's digital platform, while compatible dust extraction can be triggered wirelessly from the hammer itself.

For professional users already invested in Milwaukee M18 batteries, the 0C body-only configuration is especially attractive because there is no need to pay for additional batteries and a charger that may already be available on site.
