About this item
- 1. 4-Flute Serrated Tip for Ultra-Fast Aggressive Cutting Made of premium carbide, this drill bit set features a 4-flute serrated cutting edge that bites into hard materials instantly—delivering 30% faster drilling speed than standard smooth-tip bits. The serrated design breaks down abrasive materials (concrete, porcelain tile) into small chips, reducing resistance and enabling quick penetration without sacrificing hole quality or bit durability.
- 2. 4-Piece Essential Sizes for High-Speed Drilling Tasks Including 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, and 12mm sizes sds masonry drill bit, this set covers all fast-drilling needs for daily DIY and professional construction. Perfect for large-scale renovation projects (e.g., installing multiple bathroom tiles, drilling concrete wall anchors) where speed and efficiency are critical—cuts down on project time while maintaining consistent performance.
- 3. Wide Compatibility with Hard & Abrasive Materials As a specialised tile drill bit and concrete drill bit, it’s optimised for porcelain tile, ceramic tile, glass, concrete, and natural stone. The serrated 4-flute design minimises heat buildup by reducing friction, protecting both the bit and the workpiece from damage. No need for separate bits for different hard materials—this set handles them all with high-speed efficiency.
- 4. Spiral Shank for Anti-Slip Stability & Chip Ejection The ergonomic anti-slip spiral shank ensures a secure clamp on all drill drivers, preventing wobbling even during high-speed drilling. The spiral structure rapidly ejects chips from the drilling area, avoiding clogging that slows down work and causes uneven holes. Suitable for both beginners (easy to control) and professionals (reliable for heavy use), it’s a high-efficiency drilling tool.
- 5. Ideal for High-Volume DIY & Professional Projects This 4-piece 4-flute serrated drill set is perfect for homeowners tackling large DIY renovations and professional contractors needing consistent high-speed performance. Widely applicable to bathroom/kitchen remodelling, glass installation, concrete wall drilling, and more. The durable carbide construction resists wear from repeated use, making it a cost-effective alternative to inferior fast-drilling bits

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
