2. Safety Information

Always prioritize safety when using power tools and drill bits. Failure to follow safety guidelines can result in serious injury.

• Wear Eye Protection: Always wear safety glasses or goggles to protect against flying debris.
• Wear Hearing Protection: Use ear protection, especially during prolonged drilling operations.
• Wear Gloves: Protect hands from sharp edges and vibrations.
• Secure Workpiece: Ensure the material being drilled is firmly clamped or secured to prevent movement.
• Use Correct Speed: Operate your rotary power tool at the appropriate speed for the material and drill bit size.
• Avoid Overheating: Allow the drill bit to cool periodically, especially during continuous use, to prevent damage to the bit and workpiece.
• Inspect Bit: Before each use, inspect the drill bit for any signs of damage, wear, or dullness. Do not use damaged bits.
• Disconnect Power: Always disconnect the power tool from its power source before changing drill bits or performing maintenance.
• Keep Work Area Clear: Ensure your work area is well-lit and free from obstructions.

3. Setup

3.1 Installing the Drill Bit

1. Ensure Power Tool is Off: Verify that your rotary power tool is unplugged or its battery is removed.
2. Open Chuck: Rotate the chuck counter-clockwise to open the jaws wide enough to accept the drill bit shank.
3. Insert Bit: Insert the shank of the PROLINE CM86-5/16 drill bit into the chuck. Ensure it is inserted as far as possible without the flutes touching the chuck jaws.
4. Tighten Chuck: Rotate the chuck clockwise to securely tighten the jaws around the drill bit shank. For chucks requiring a key, use the key to ensure maximum tightness. A loose bit can be dangerous and cause inaccurate drilling.
5. Verify Security: Gently pull on the drill bit to confirm it is firmly seated and will not slip during operation.

4. Operating Instructions

4.1 Drilling Masonry Materials

1. Select Appropriate Speed: For masonry drilling, generally use a slower speed setting on your rotary power tool. Consult your power tool's manual for specific recommendations.
2. Mark Drilling Location: Clearly mark the exact spot where you intend to drill.
3. Start Slowly: Begin drilling at a slow speed with light pressure to create a pilot indentation and prevent the bit from wandering.
4. Apply Steady Pressure: Once the bit has engaged the material, increase the speed and apply steady, firm pressure. Avoid excessive force, which can overheat the bit or damage the power tool.
5. Clear Debris: Periodically withdraw the drill bit from the hole to allow debris to clear from the flutes. This is especially important for deep holes.
6. Maintain Straight Angle: Keep the drill bit perpendicular to the surface to ensure a straight hole.
7. Cooling: For prolonged drilling, especially in hard materials, allow the bit to cool down to prevent premature wear.
8. Finish Drilling: Once the desired depth is reached, slowly withdraw the drill bit from the hole while the drill is still rotating.

4.2 Recommended Materials

This drill bit is designed for optimal performance in:

• Light to medium hard building materials
• Materials that produce coarse powder or gravel when drilled

Caution: Not recommended for use in materials requiring hammer drill action unless specifically designed for such use by the power tool manufacturer.

5. Maintenance and Storage

5.1 Cleaning

After each use, clean the drill bit to remove any dust, debris, or residue. A stiff brush or compressed air can be used. Ensure the bit is dry before storage.

5.2 Inspection

Regularly inspect the carbide tip for chipping or excessive wear. Check the flutes for any obstructions or damage. A dull or damaged bit should be replaced to ensure safety and efficiency.

5.3 Storage

Store drill bits in a dry environment to prevent rust. Keep them in their original packaging or a dedicated drill bit case to protect the tips and prevent accidental injury. Store out of reach of children.
