Description
Adiseal Ultimate 6mm x 150mm Masonry & Multi-Material Drill Bit Carbide
Adiseal Ultimate 6mm masonry and multi-material drill bit is the fastest and most durable drill bit for non-hammer drilling. Engineered with a high-strength carbide tip and a 1/4 inch quick-change hex shank, this patented bit drills faster and lasts longer than leading competitors like DeWalt, Milwaukee, Makita and Bosch in testing. Designed for precision, it drills cleanly through masonry, concrete, brick, stone, ceramic tile, wood, and plastic without the need for a hammer drill, reducing the risk of substrate breakage and vibration-related hand injuries like vibration white finger syndrome.

How do you use the Adiseal Ultimate 6mm 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 6mm 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 6mm Masonry Drill Bit
What is the primary use for the Adiseal Ultimate 6mm masonry drill bit?
The 6mm bit is the industry-standard size for red wall plugs. Its patented non-hammer design ensures that the 6mm hole is perfectly cylindrical and precise, providing maximum grip and pull-out resistance for the plug in brick, stone, or concrete.
Does the 6mm Adiseal bit fit into a standard impact driver?
Yes. It is equipped with a universal 1/4 inch quick-change hex shank that fits all standard impact drivers and cordless drills. To maximize the life of the carbide tip, ensure the tool is set to rotary-drill mode rather than the impact or hammer setting.
Why is non-hammer drilling better for 6mm holes in masonry?
Using a hammer drill for small 6mm holes often causes the brick to “spall” or blow out at the back, weakening the fixing. The Adiseal Ultimate 6mm bit shears through material using high-speed rotation, preserving the structural integrity of the wall and reducing noise.
How does the Adiseal Ultimate 6mm bit help prevent Vibration White Finger (VWF)?
Because the bit is engineered to drill through hard concrete and stone without a hammer mechanism, it significantly reduces the Hand-Arm Vibration (HAV) levels transmitted to the user. This makes it a safer choice for professionals drilling multiple 6mm holes throughout the day.
Is the 6mm Adiseal bit suitable for drilling through wood and plastic?
Yes, this is a true multi-material bit. It provides clean, fast holes in wood, plastic, and fiberglass. While optimized for masonry, its versatility allows contractors to switch between substrates without changing bits.
