Product Information

Full details

The B&Q 3-piece long masonry drill bit set is designed for professional contractors and DIY enthusiasts who require extended reach for deep-hole drilling in challenging materials like concrete, brick, and granite. Featuring a robust tungsten carbide tip, these bits excel in heavy-duty construction tasks by combining speed with durability, though their 400mm length requires a steady hand to prevent bit vibration or wandering during the initial entry.

FAQs

Are these bits compatible with SDS drills?

These bits are designed for standard chuck drills. Please check your drill manual to ensure compatibility with the specific shank size.

Can I use these for drilling through ceramic tiles?

Yes, they are suitable for ceramics, but start drilling at a very low speed without hammer action to avoid cracking the tile surface.

What is the primary material composition of the tip?

The bits feature a strengthened tungsten carbide tip for high durability.

Should I use cooling lubricant?

While the advanced coating reduces heat, periodic cooling or clearing of debris is recommended for deep-hole drilling.

What sizes are included in the set?

The set includes 8mm, 10mm, and 12mm drill bits.

Troubleshooting

Bit is wandering during the start of the hole

Use a center punch to create a small indentation or start drilling at a slower speed to secure the bit path before increasing RPM.

Excessive heat during drilling

Remove the bit periodically to clear dust from the hole and reduce pressure, allowing the spiral design to evacuate debris.

Bit vibrating excessively

Ensure the drill chuck is fully tightened and that the drill is held perpendicular to the surface.

Pros and Cons

Pros

Extended 400mm length for deep-set applications
High-heat resistance due to advanced surface coating
Excellent debris extraction via optimized spiral design
Highly durable tungsten carbide tip composition

Cons

Not intended for precision drilling in delicate materials
Long length requires careful alignment to avoid bending
Requires significant torque from the drill for larger diameter holes

Setup, Compatibility & Care

To ensure optimal performance, verify that your drill chuck is properly tightened before starting, as the 400mm length creates increased leverage. These bits are compatible with most standard electric and cordless drills that accept shank sizes corresponding to the 8mm, 10mm, and 12mm specifications. After use, wipe the bits with a dry cloth to remove grit and apply a light machine oil if storing in a humid environment to maintain the rust-resistant finish. Avoid dropping the bits on concrete floors, as the hardened tungsten carbide tips can chip upon high-impact contact.
