Product Description

INCREASE CUTTING SPEED

• The split point tip is a 118-degree X-shaped design that doesn't slip easily, allowing you to cut faster in multiple uses.This also ensures you get a sharp cut on a variety of materials.

SPIRAL FOUR FLUTE

• 4-flute design prevents the metal filler from splashing everywhere, and removes the chips easily, so as to achieve smoother drilling.
• High-speed steel and titanium coatings ensure durability, smooth chip evacuation, low cutting resistance, and clean burr removal.

1/4"(6.35mm) HEX SHANK

• Quick change: The 1/4 inch hex shank fits easily and securely into all power tools to prevent slippage and shedding during rotation.

SUITABLE FOR ELECTRIC DRILL

Hand drill, cordless drill, bench drill, drill wrench and other suitable models. Special attention should be paid to: the power of the electric drill used should be greater than 20V, of which the rechargeable drill is greater than 12V.

User Guide and Tips:

1. Always wear appropriate safety gear

2. Securely clamp or hold down the workpiece

3. Start with Smaller Steps: When drilling a hole in increments, start with the smaller steps and gradually increase to larger sizes.

4. Avoid applying excessive force. During the use of the drill bit, the rotation speed should not be too fast. The drill bit must be drilled vertically with the workpiece to be processed. When the drill is stuck, do not force the drilling. It is better to take it out and continue drilling.

5. For harder materials like stainless steel or metal sheet, it is recommended to use cutting fluid or lubricant to reduce friction and heat build up. When drilling large diameter holes and the hardness of the material is high, water should be added to cool the drill bit. Water cooling while drilling can effectively prolong the life of the drill bit.

6. If you're drilling multiple holes in quick succession, take short breaks to allow the bit to cool down.
