Diamond Drill Bits – Precision, Strength, and Performance You Can Rely On

Perfect for Builders, Tilers, Stonemasons, and DIY Professionals Across New Zealand

When you need to cut through the toughest materials with precision and ease, nothing performs like a Diamond Drill Bit. Engineered for strength, speed, and accuracy, these specialised drill bits are designed to handle hard surfaces such as tile, glass, granite, marble, concrete, and stone — materials that standard bits simply can’t match.

Whether you’re a professional tradesperson drilling holes for plumbing and fittings, or a DIY enthusiast tackling home renovations, diamond drill bits deliver clean, smooth holes every time. Built for durability and precision, they’re a must-have for anyone serious about high-quality workmanship in New Zealand’s construction and home improvement industries.

Description – Diamond Drill Bits

Diamond drill bits feature industrial-grade diamond particles bonded to the cutting edge, providing unmatched hardness and cutting ability. They’re specifically designed to drill through materials that would quickly wear down conventional steel bits.

These bits work by grinding away material rather than cutting, producing cleaner, smoother results with minimal chipping. Available in dry-cut and wet-cut versions, diamond drill bits are ideal for use with both handheld drills and drill presses.

Constructed with premium steel cores, vacuum-brazed diamond segments, or electroplated coatings, they deliver exceptional performance, long service life, and consistent precision — even under demanding use.

Construction and Design

• Material: High-strength carbon steel or alloy core with industrial-grade diamond coating or vacuum-brazed cutting edge.
  
• Cutting Edge: Bonded diamond grit provides superior hardness and abrasion resistance.
  
• Sizes: Available in diameters ranging from 5mm to 150mm to suit various applications.
  
• Shank Type: Round, hex, or SDS shanks compatible with common drills used in NZ.
  
• Cooling Method: Dry or wet drilling options for enhanced lifespan and performance.
  
• Finish: Polished, anti-corrosion surface for durability and smooth drilling.
  

Precision-engineered to handle New Zealand’s toughest materials, diamond drill bits deliver clean, efficient holes with minimal effort or material damage.
