Do all hammer drills use the same drill bits?
No. Standard hammer drills with 1/2-inch keyless chucks, such as the DCA 20V or DEWALT DWD520K, use standard round-shank bits. Conversely, rotary hammers like the DEWALT D25263K and the 9-amp SDS-Plus model require specific SDS-Plus shank bits. These bits are designed to lock into the hammer mechanism to handle the high-impact force of the tool. Always verify your drill's chuck type before purchasing bits to ensure they are compatible and safe for use with your specific drill model.
How do I choose between a pistol grip and a rotary hammer?
Choose based on your primary task. The pistol-grip DEWALT DWD520K is a versatile choice for drilling wood, metal, and light masonry. A rotary hammer, such as the D25263K, is a specialized tool for drilling holes into hard concrete. If your work involves a mix of materials, a pistol-grip hammer drill is often more convenient. If your work consists almost exclusively of drilling into masonry or concrete, the specialized impact mechanism of a rotary hammer will provide significantly better results and faster drilling speeds.
