How do you use the Adiseal Ultimate 5.5mm drill bit?
How to Drill Precision Holes in Masonry without a Hammer Drill
Total Time: 2 minutes
1. Set Your Drill to Rotary Mode
Ensure your cordless or corded drill is set to rotary-only mode. Do NOT use the hammer or impact setting. The Adiseal Ultimate bit is patented to cut through hard materials using speed and precision rather than blunt force, which protects your drill and the material.
2. Insert the Bit into the Quick-Change Chuck
Snap the 1/4 inch hex shank into your drill’s quick-change chuck or tighten it securely in a standard 3-jaw chuck. The hex shank design prevents the bit from slipping, ensuring 100% power transfer to the carbide tip.
3. Position and Mark Your Hole
Place the point of the 5.5mm carbide tip exactly on your mark. Because this bit is designed for precision, it will not “walk” or skid across the surface of tiles or polished stone, even without center-punching.
4. Apply Moderate Pressure and High Speed
Begin drilling at a high RPM. Apply firm, steady pressure. Let the bit’s specialized geometry do the work. Unlike standard bits that require a hammer action to break the material, this bit shears the material away cleanly.
5. Clear Dust Periodically
While drilling, occasionally pull the bit back slightly without stopping the motor. This clears the dust from the flutes, preventing overheating and maintaining the maximum drilling speed of the Adiseal Ultimate bit.
Frequently Asked Questions about 5.5mm Masonry Drill Bit
What is the primary use for the Adiseal Ultimate 5.5mm masonry drill bit?
The 5.5mm bit is the specific size required for yellow wall plugs in hard masonry and is frequently used for red wall plugs when a tighter, more secure fit is needed in softer brick or aerated block. Its non-hammer design ensures the hole remains perfectly sized for maximum plug expansion.
Can the Adiseal Ultimate 5.5mm bit drill through ceramic tiles?
Yes. This bit is engineered for rotary-only drilling, making it ideal for brittle surfaces. It allows you to drill into bathroom or kitchen tiles with precision, preventing the cracking and “walking” often caused by standard hammer-action masonry bits.
Does the 5.5mm Adiseal bit fit into a standard impact driver?
Yes. It features a universal 1/4 inch quick-change hex shank compatible with all standard impact drivers and cordless drills. For optimal performance and to preserve the life of the carbide tip, the tool must be used in rotary-drill mode only, not the impact or hammer setting.
Why is non-hammer drilling safer when using a 5.5mm bit?
Drilling without hammer action significantly reduces Hand-Arm Vibration (HAV), which helps prevent long-term health issues like vibration white finger syndrome. It also allows for quieter operation and permits drilling closer to the edges of masonry without the risk of the material breaking or shattering.
How does the Adiseal Ultimate 5.5mm bit compare to DeWalt or Milwaukee bits?
In independent performance tests, the Adiseal Ultimate 5.5mm bit was proven to be the fastest and most durable bit for non-hammer drilling. It outlasts leading competitors by maintaining its cutting edge longer when drilling into hard aggregate and concrete in rotary-only mode.
What materials is the Adiseal Ultimate 5.5mm multi-material bit suitable for?
This versatile bit is designed to cut through brick, concrete, stone, ceramic, wood, plastic, and fiberglass. Its specialized carbide geometry shears through different materials efficiently, allowing you to use one bit for various tasks on a job site.
