S814 drill bit

Description

1. Product Overview
The S814 drill bit is a high-performance industrial drilling tool engineered for precision penetration in demanding metal, concrete, and reinforced steel applications. Its primary use spans heavy fabrication, construction, mining infrastructure, and industrial maintenance operations where bit failure causes costly downtime. The key value proposition is exceptional durability and cutting efficiency derived from advanced carbide/HSS composition and optimized geometry, delivering 30–50% more holes per bit than standard alternatives. Strategically, this product is critical for enterprises seeking to reduce total cost of drilling by minimizing tool changes, enhancing operator safety, and maintaining consistent production throughput in high-intensity environments.

2. Key Specifications & Technical Characteristics

• Material Components: Premium tungsten carbide tip (AWC-grade) bonded to high-speed steel (HSS) or cobalt-enhanced alloy body (5–8% Co)

• Grade/Purity: Industrial-grade carbide >92% purity; HSS meets ASTM A681 standards

• Physical Characteristics:

  • Form: Straight-flute spiral with dual-cutter carbide tip (SDS-Plus compatible)

  • Color: Titanium nitride (TiN) gold-coated tip, black oxide body

  • Particle/Tip Geometry: 120° faceted point angle, web-thinned tapered configuration

  • Density: 13.5 g/cm³ (carbide tip); 7.8 g/cm³ (steel body)

• Packaging Options: Bulk cartons (100 pcs), master drums (500 pcs), or custom palletized shipping for 20MT loads

• Shelf Life: 10+ years when stored in dry, climate-controlled conditions (no degradation of cutting geometry)

3. Core Industrial Applications

• Primary Industries: Construction (reinforced concrete), oil & gas (casing drilling), metal fabrication (stainless/tool steel), mining infrastructure, heavy equipment repair

• Specific Operational Use Cases:

  • Drilling through 300-series stainless steel, spring steel, and cast iron in structural beams

  • Rapid penetration of high-strength concrete with embedded rebar (SDS-Plus hammer drills)

  • Thick plate drilling (≥25mm) where standard bits deflect or break

• Performance Advantages:

  • Efficiency: 50% more holes per bit vs. standard HSS due to polished low-friction surface

  • Durability: Carbide tip resists wear in hardened steel; cobalt body prevents heat softening up to 650°C

  • Cost Advantage: 30% lower total cost per hole by reducing tool-change frequency and operator downtime
