Metabo HPT Demolition Hammer, AC Brushless Motor, SDS Max, 27 Pound, Aluminum Housing Body, User Vibration Protection - H45MEY

Metabo HPT Demolition Hammer, AC Brushless Motor, SDS Max, 27 Pound, Aluminum Housing Body, User Vibration Protection  - H45MEY

• Ultra efficient AC Brushless motor that permits the use of extra-long extension cords with reduced power loss
• Superior performance when using a generator due to an internal inverter circuit that regulates uneven power supply
• AHB (Aluminum Housing Body) construction significantly enhances the internal and external durability of the tool
• UVP (User Vibration Protection) technology greatly reduces vibration for comfortable extended use and fewer vibration related injuries via the use of internal counterweights and springs
• 1,430-2,850 BPM full load max impact rate to quickly remove stubborn material

What our Experts Think

• Professional‑level demolition performance
  The Metabo HPT Demolition Hammer (H45MEY) delivers high impact force (≈9.9 ft‑lbs) and a fast impact rate (≈1,430–2,850 BPM) to break up concrete, masonry, tile, and other hard materials quickly and efficiently.
• AC brushless motor — more power, less maintenance
  The AC brushless motor runs cooler, operates with reduced power loss over long extension cords, tolerates voltage dips (e.g., generator use), and eliminates brush maintenance, extending tool life.
• User Vibration Protection (UVP)
  Built‑in UVP technology reduces vibration transmitted to the operator, lowering fatigue and the risk of vibration‑related injuries during prolonged use.
• Rugged aluminum housing body (AHB)
  The metal housing improves durability and jobsite toughness, protecting internal components from impacts and wear far better than plastic casings.
• Quick bit changes & angle versatility
  Quick‑release SDS Max shank and adjustable bit angle positions make setup and transitions fast and precise across applications.
• Comfort and control for heavy work
  Ergonomic grip, 360° adjustable side handle, and two‑finger trigger with lock‑on enhance comfort and control, even in demanding chipping or scaling jobs.
• Generator‑friendly and jobsite ready
  Internal inverter circuitry helps the hammer maintain performance when powered by generators or long cord runs—a bonus on remote or large job sites.
• Great balance of weight and power
  At around 27 lb, it offers a strong power‑to‑weight ratio for demolition hammers in its class, balancing mobility with serious breaking force.

Q&A

Q: What type of tool is this?
A: This is a professional‑grade SDS Max demolition hammer designed for heavy concrete chipping, chiseling, and demolition tasks on construction sites and renovation jobs.

Q: What power and motor technology does it use?
A: It features an AC brushless motor for higher efficiency, reduced power loss over long extension cords, longer tool life, and maintenance‑free operation (no brushes to change).

Q: How much impact power and speed does it deliver?
A: The tool delivers an impact rate of about 1,430–2,850 BPM with approximately 9.9 ft‑lbs of impact energy, enabling fast removal of stubborn concrete and masonry.

Q: What is SDS Max — and why is it beneficial?
A: SDS Max is a heavy‑duty bit shank standard that accepts large demolition and chiseling bits for deep concrete removal and heavy material breakdown.

Q: How does the vibration protection work?
A: User Vibration Protection (UVP) technology reduces vibration, minimizing user fatigue and lowering the risk of vibration‑related injury during extended use.

Q: How durable and jobsite‑ready is it?
A: It has a robust aluminum housing body (AHB) that provides enhanced impact resistance and long tool life under heavy jobsite use.

Q: What comfort and control features are included?
A: Includes an ergonomic soft, non‑slip grip, a large two‑finger trigger switch with lock‑on, and a 360° adjustable side handle for optimal control and reduced fatigue.

Q: What’s included with the tool?
A: Typically supplied with a plastic carry case, a side handle, and a bull point SDS Max bit so you can get to work right away.

Maintenance Tips

• Clean After Use: Wipe down the tool exterior after each session to remove dust and debris; compressed air at the bit holder area helps keep the mechanism clear.
• Check Bits & Bit Holder: Inspect SDS Max bits before installation; replace worn or chipped bits to reduce stress on the hammer mechanism.
• Lubricate Bit Holder: Apply a little grease in the bit holder periodically (as recommended in the manual) to ensure smooth bit insertion and extraction.
• Monitor Brushless Motor: The AC brushless design eliminates brush maintenance, but checking for unusual noises or heat helps catch motor issues early.
• Use Appropriate Power Supply: Avoid voltage drops by using proper extension cords and avoid generators without stable output; the internal inverter improves performance but good supply reduces stress.
• Control Vibration: Use User Vibration Protection (UVP) features and take breaks to reduce fatigue and wear on internal components.
• Secure Fasteners: Periodically check and tighten housing screws and handles to prevent loosening from heavy vibrations.
• Inspect Power Cord: Look for frays or damage before each use; damaged cords can reduce performance and present safety hazards.
• Store Properly: After use, unplug, clean thoroughly, and store in a dry case or area to prevent moisture‑related corrosion.
