Quick Answer: Laser welded ARIX core drill bits outperform standard bits through three key advantages — laser welding creates a metallurgical bond at 1,300°C+, eliminating segment detachment risk; ARIX diamond placement technology positions every diamond at an optimal cutting angle for continuous self-sharpening; and dry/wet dual-use design allows the same bit to perform reliably with or without water supply. Compared to sintered bits, ARIX laser bits drill 30–50% faster and last 2–3× longer. Below, we break down the technology, selection criteria, real-world performance, and a procurement checklist.

• Through concrete: Hard aggregates (granite, basalt) cause abrasive wear on the diamond matrix, continuously consuming the bond material.
• Through rebar: The cutting mechanism shifts abruptly from grinding to shearing and impact. Sintered bonds, designed for steady abrasion, often fracture or lose segments under these sudden loads.

1. Stalling on rebar — diamonds become "glazed" in the matrix, unable to expose fresh cutting edges.
2. Burn-out — heat buildup during dry cutting softens the bond, deforms the segment, and can compromise operator safety.
3. Hole drift and edge chipping — the bit deflects at rebar intersections, producing inaccurate holes and damaged walls.

• Traditional process: Diamond grit is randomly mixed into metal powder → hot-press sintered → distribution is unpredictable, with clustered and barren zones.

• ARIX process: Each diamond is positioned at a preset spacing, orientation, and protrusion height → hot-pressed / laser welded → uniform distribution across the cutting face, with every diamond held at its most aggressive cutting angle.

• High-rise construction without water access, interior renovations, finished spaces
• Requires: heat-resistant bond, carbonization-proof diamonds, efficient debris evacuation

• Sites with water supply, large-diameter deep holes (≥50mm), continuous multi-hole operations
• Requires: adequate cooling, fast slurry removal, clog prevention

1. Matrix powder formula is engineered for temperatures up to 800°C, incorporating cobalt and tungsten for thermal stability. The bond does not soften during dry cutting.
2. Laser weld seams withstand temperatures far exceeding the 600–700°C generated in dry cutting. No de-brazing risk.
3. ARIX-placed diamonds have uniform protrusion height, keeping debris channels open during dry cutting — no powder clogging.

• Procurement manager's problem: Silver brazed bits from a previous supplier averaged only 8–10 holes before de-brazing.
• After switching to SANG ARIX laser welded bits: Each bit completed 55–65 holes (alternating wet and dry), with zero segment loss.
• Total cost savings: Bit consumption reduced by 75%, project timeline shortened by 3 days (reduced bit-change downtime).

• Engineering team feedback: SANG's ARIX bits showed no skipping or jamming when hitting rebar. Average cutting speed ~40% faster than their previous sintered bits.
• Key advantage: ARIX-placed diamonds maintained active cutting edges through rebar contact — no collective blunting.
• Follow-up: The contractor added SANG bits to the specified consumables list for four subsequent municipal projects.

• Performance: SANG dual-use bits maintained steady drilling speed through 30+ consecutive dry holes, with zero burn-out incidents.
• Distributor follow-up: After client trial, the Australian distributor placed a repeat order of 500 units to cover both mining and civil infrastructure channels.
