It is engineered to withstand the high – torque demands of drilling and chiseling in hard materials. The motor is enclosed in a durable housing that protects it from dust, debris, and impact.
  • Drive Train: The motor is connected to the chuck through a complex drive train. This drive train transfers the rotational energy of the motor to the drill bit or chisel. In hammer drilling mode, an additional mechanism is engaged to provide the hammering action. The drive train components are made of high – quality materials to ensure long – lasting performance and reliability. They are also designed to be efficient, minimizing energy loss and maximizing the power delivered to the working end of the tool.

4.2 Chuck and Bit System

  • SDS – Max Chuck: As mentioned earlier, the 11264EVS features an SDS – Max chuck. The SDS – Max system is designed for quick and secure bit changes. The chuck has a unique slotted design that allows the bit to be inserted easily. Once inserted, the bit is locked in place by a spring – loaded mechanism. This ensures that the bit remains firmly attached during operation, even under high – stress conditions.
  • Bit Compatibility: The SDS – Max chuck is compatible with a wide range of bits. These bits are specifically designed for use in power hammers and come in various sizes and types. For drilling, there are bits with different diameters and tip designs to suit different materials. For chiseling, there are chisels with different shapes, such as flat chisels for removing tiles and pointed chisels for breaking up concrete. When selecting a bit, make sure it is appropriate for the material you are working on and the task at hand.

4.3 Operating Modes

  • Hammer Drilling Mode: In hammer drilling mode, the tool combines the rotational motion of the drill bit with a rapid hammering action. The hammering action is achieved through a mechanism that uses a piston – like system. As the motor rotates, it drives a cam that causes the piston to move up and down rapidly. This piston strikes a striker, which in turn hits the drill bit, providing the hammering force. The combination of rotation and hammering allows the bit to penetrate hard materials like concrete quickly and efficiently.
  • Drilling – Only Mode: When the 11264EVS is set to drilling – only mode, the hammering mechanism is disengaged. Only the rotational motion of the motor is transferred to the drill bit. This mode is useful for drilling holes in softer materials such as wood, plastic, or metal. In this mode, the tool functions similar to a regular drill, and the variable speed control can be adjusted to suit the material being drilled.
  • Chiseling Mode: In chiseling mode, the rotation of the chuck is locked, and only the hammering action is active. The chisel is inserted into the SDS – Max chuck, and the rapid hammering force is used to break up or shape the material. This mode is commonly used for tasks such as removing old mortar, breaking up small sections of concrete, or carving stone.

4.4 Variable Speed Control

  • Speed Adjustment Dial: The 11264EVS is equipped with a variable speed adjustment dial. This dial allows the user to control the rotational speed of the drill bit or chisel. The dial is usually marked with different speed settings, ranging from low to high. By turning the dial, you can increase or decrease the speed according to the requirements of the task. For example, when starting a hole in a hard material, a lower speed is recommended to prevent the bit from slipping or breaking. As the hole progresses, you can gradually increase the speed for faster drilling.
  • Electronic Speed Control: In addition to the mechanical speed adjustment dial, the 11264EVS also features electronic speed control. This technology helps to maintain a consistent speed even under varying load conditions. When the tool encounters resistance, the electronic speed control system automatically adjusts the power output of the motor to keep the speed constant. This ensures smooth and efficient operation, especially when working on tough materials.

4.5 Vibration Control System

  • Anti – Vibration Handles: The tool is designed with anti – vibration handles. These handles are made of a special material that absorbs and dampens vibrations. The shape and texture of the handles are also ergonomically designed to provide a comfortable grip while reducing the transfer of vibrations to the user’s hands. The second handle, which is included with the tool, also has anti – vibration features. When using the tool in overhead or awkward positions, the second handle can be used to provide additional support and help reduce vibration.
  • Internal Vibration – Dampening Mechanisms: Inside the tool, there are also internal vibration – dampening mechanisms. These mechanisms are designed to isolate the vibrating components of the tool from the rest of the body. For example, the motor and the hammering mechanism are mounted on special rubber – like mounts that absorb vibrations. This helps to further reduce the amount of vibration that reaches the user’s hands, improving comfort and reducing the risk of fatigue during long – term use.

5. Tool Tips (Continued)

  • Material – Specific Bits (Continued): For metal, high – speed steel (HSS) bits are a good choice. They can cut through metal with relative ease. If you’re working with wood, twist drill bits are commonly used. For very hard woods, you might consider using bits with a cobalt coating, which provides enhanced durability and cutting performance.
  • Bit Size and Hole Requirements: Always choose a bit size that matches the diameter of the hole you need to drill. If the bit is too small, you may need to drill multiple holes and then widen them, which is time – consuming. If the bit is too large, it can cause the material to crack or break. Also, consider the depth of the hole. Make sure the bit is long enough to reach the required depth.
  • Inspect Bits Regularly: Before each use, inspect the bits for any signs of wear, damage, or dullness. A dull bit can cause the tool to overheat, require more force to operate, and produce a poor – quality hole. If a bit is damaged, such as having a chipped carbide tip, replace it immediately to avoid further problems and ensure safety.

5.2 Drilling Techniques

  • Marking the Hole Location: Use a center punch or a pencil to mark the exact location where you want to drill the hole. This helps to prevent the bit from wandering when you start drilling. For more precise work, you can use a template or a guide to ensure consistent hole placement.
  • Starting the Hole: When starting a hole, especially in hard materials like concrete, start at a low speed. Apply light pressure and let the bit gradually penetrate the surface. Once the bit has made an indentation, you can increase the speed and pressure slightly. This technique helps to keep the bit on track and reduces the risk of it slipping.
  • Drilling at the Right Angle: Keep the tool perpendicular to the surface of the material you are drilling. This ensures that the hole is straight and of the correct diameter. If the tool is angled, the hole may be oval – shaped or off – center. You can use a square or a level to help you maintain the correct angle.

5.3 Chiseling Techniques

  • Positioning the Chisel: When chiseling, position the chisel at the correct angle. For most chiseling tasks, a 30 – to 45 – degree angle is ideal. This angle allows the chisel to effectively break up the material without getting stuck. Use the chisel’s flat surface for removing large areas of material and the pointed end for more detailed work, such as carving or shaping.
  • Controlled Strikes: Instead of using excessive force in one big strike, use a series of short, controlled strikes. This gives you better control over the chiseling process and reduces the risk of accidentally damaging surrounding areas. You can also use a mallet to assist with the chiseling if the tool’s hammering action isn’t sufficient for very tough materials.
  • Clearing Debris: Regularly clear the debris from the chiseling area. Buildup of debris can interfere with the chiseling process and may cause the chisel to bounce or slip. You can use a brush or a vacuum cleaner to remove the debris as you work.
