Rosh 5 Pcs Concrete/Masonry Drill Bit Set

Rosh 5 Pcs Concrete/Masonry Drill Bit Set – High Performance Carbide-Tipped Drilling Kit

The Rosh 5 Pcs Concrete/Masonry Drill Bit Set (RS1408S) is a high-performance, essential kit for anyone working with hard materials. This set includes five of the most frequently used drilling diameters (5/32″, 3/16″, 1/4″, 5/16″, and 3/8″), making it ideal for standard home repair and anchoring tasks. Each bit features a robust, reinforced carbide tip that is engineered for superior hardness and wear resistance, guaranteeing maximum durability and a longer operational life when drilling in tough concrete, brick, and block. The deep, single-flute spiral design ensures fast, efficient removal of dust and debris from the hole, which leads to quicker drilling and reduces the risk of bit binding or overheating. These bits are designed for optimal performance when paired with a hammer drill, providing the impact energy necessary for masonry penetration.

• Any job requiring precision drilling into hard materials.

Application Instructions

• Secure Chuck: Insert the bit fully and securely tighten the drill’s 3-jaw chuck.
• Drill Setting: Set the power drill to the Hammer Drill (Impact) mode.
• Start: Align the bit on the marked point and start at a low speed to establish a clean cut.
• Drilling: Gradually increase to full speed, applying steady, forward pressure without excessive force.
• Clean: Withdraw the bit occasionally to clear dust and cool the tip, particularly in deep holes.

Pro Tips

• For long life, avoid overheating the carbide tip; withdraw frequently or use water cooling if possible.
• Use the smallest bit (5/32″ or 3/16″) as a pilot hole for the larger bits to improve accuracy and speed.
• Always wear safety glasses, hearing protection, and a dust mask when hammer drilling.
• Ensure the power drill is capable of the hammer action required for concrete.
• Store the bits in the provided case to protect the tips from chipping and damage.
