MEDIUM BREAKER DRILLS

Makita HR3540C AVT SDS-Plus Rotary Hammer: Powerful Drilling & Chiselling with Advanced Anti-Vibration Technology

The Makita HR3540C AVT SDS-Plus Rotary Hammer is a robust and versatile professional-grade corded tool designed for demanding drilling in concrete, masonry, and stone, as well as efficient chiselling applications. It combines a powerful motor with Makita's renowned Anti-Vibration Technology (AVT), offering impressive performance while significantly enhancing user comfort and reducing fatigue during prolonged operation.

Features

• Powerful 850W Motor: Delivers strong and consistent power for heavy-duty drilling and chiselling tasks, ensuring reliable performance even under challenging conditions. Available in both 110V and 240V versions.
• High Impact Energy (5.1 Joules EPTA-Procedure 05/2009): Provides formidable hitting power, allowing for fast and efficient drilling and powerful breaking of concrete, brick, and other masonry materials.
• SDS-Plus Tool Holder: Features a robust SDS-Plus chuck, enabling quick, tool-free bit changes and ensuring efficient power transfer for various drilling and chiselling bits.
• 3-Mode Operation: Offers versatility for a wide range of applications:
  • "Rotary Only" Mode: For drilling in wood, metal, and plastics (with appropriate drill bits and adaptor).
  • "Rotary Hammer" Mode: For hammer drilling (drilling with impact) into concrete, brick, and stone. Ideal for holes up to 35mm in concrete (with solid bit) and up to 90mm with TCT core bits.
  • "Hammer Only" (Chiselling) Mode: For breaking, chipping, and chiselling applications, such as removing tiles, chasing walls, or light demolition work.
• Advanced Anti-Vibration Technology (AVT): Makita's cutting-edge AVT system significantly reduces vibration transmitted to the user. This is achieved through a multi-component system:
  • Vibration Absorbing Housing: The ergonomic main handle and upper housing are effectively isolated by springs, separating them from the tool's vibration-generating components.
  • Active Dynamic Vibration Absorber: An internal counterweight mechanism moves in the opposite direction to the piston, actively neutralizing dynamic vibrations.
  • Damping Spring: A specially designed spring absorbs vibrations at the bit end, further reducing overall tool vibration. This comprehensive AVT system results in exceptionally low vibration levels, allowing for extended continuous operation times without reaching Hand-Arm Vibration (HAV) exposure limits, significantly increasing usable work time.
• "Soft No-Load" Function: Automatically reduces the motor speed and impact action when the tool is idling (not under load). This minimizes vibration to the user's hands when repositioning the tool and reduces wear on the internal components.
• Soft Start Feature: Ensures a smooth and controlled start-up, preventing sudden jolts and allowing for more accurate bit placement, especially crucial when beginning a hole.
• Constant Speed Control: Electronically regulates power to maintain consistent speed and impact energy even when the tool is under heavy load, ensuring maximum drilling and chiselling efficiency.
• Torque Limiter (Safety Clutch): Automatically disengages the gears if the drill bit jams, protecting both the user from sudden rotational forces (kickback) and the tool's motor and gears from damage.
• LED Service Light & Power Indicator:
  • Service Light: Illuminates to indicate when carbon brushes are nearing the end of their life, allowing for proactive maintenance and preventing unexpected downtime.
  • Power Light: Confirms that the tool is connected to the power supply.
• Recessed Mode Change Lever: The operation-mode change lever is strategically located on the top of the motor housing, reducing the possibility of accidental breakage when the tool is laid down on a surface.
• Variable Speed Trigger: Provides precise control over the speed, allowing the user to match the drilling or chiselling rate to the material and application for optimal results.
• Lock-on Switch (for Chiselling): In chiselling (hammer only) mode, the on/off switch can be locked on for continuous operation, reducing finger fatigue during extended breaking tasks.
• Chisel Bit Angle Setting: Allows for precise adjustment of the chisel bit angle, providing optimal working angles for various chiselling tasks.
• Durable Construction: Features robust construction, including an aluminium gear housing, designed to withstand the rigours of heavy-duty site work.
• Double Insulation: Provides an essential layer of protection against electrical shock, enhancing user safety.
