I. Product Specifications
- Product Name: STANBAL Professional Hex Shank Masonry Drill Bit (Tile Capable / 5,000 PSI Concrete Rated)
- Shank Type: Standard 6.35 mm (1/4") Quick-Release Hex Shank, perfectly compatible with impact drivers, hex drivers, and standard power drills.
- Suitable Materials: Specially engineered for tiles, tile & concrete composite materials, high-PSI concrete, brickwork, and natural stone.
II. Materials & Engineering
- Premium Alloy Steel Body (High-Toughness Anti-Vibration Structure):
- Crafted from high-grade alloy steel and precision-engineered using specialized heat treatment (quenching and tempering).
- Features exceptional torsional strength and shock absorption, effectively dampening vibration under high-impact forces to prevent bending or body failure.
- Premium Tungsten Carbide Tip (Extreme Wear Resistance & Composite Cutting):
- Features a high-grade micro-grain tungsten carbide tip sintered under extreme temperature and pressure.
- Delivers ultra-high hardness and wear resistance; the specialized tip geometry accurately anchors and pierces hard ceramic/vitrified tiles before smoothly penetrating the underlying concrete without chipping or dulling.
III. Key Features
- One-Step Penetration for Tile & High-Strength Concrete: Specially optimized for tile-over-concrete applications (up to 5,000 PSI), ensuring precise hole placement without slipping or cracking delicate tile surfaces.
- Quick-Release Hex Shank: Standard 6.35 mm hex shank allows fast, effortless accessory swaps, significantly boosting productivity on the job site.
- Efficient Rapid Dust Evacuation: Optimized spiral flutes quickly clear away tile dust and masonry debris, reducing friction and maximizing drilling speed.
- Extended Service Life: Durable carbide composite construction delivers exceptional longevity and cost-efficiency under standard operating conditions.
IV. Product Highlights
- Tile & Composite Material Capable: Optimized for tile-over-masonry walls; anchors precisely to minimize the risk of cracking tiles.
- Rated for 5,000 PSI High-Strength Concrete: High toughness and hardness handle high-density structural concrete with ease.
- Standard 6.35 mm Quick-Release Hex Shank: Broad compatibility with impact drivers and cordless drills for quick bit changes.
- Premium Carbide Tip & Optimized Flutes: Superior heat dissipation and rapid dust extraction extend overall tool lifespan.
V. Usage & Maintenance Guide
- Proper Usage:
- Tile Drilling Technique: When starting on ceramic or vitrified tiles, begin in Rotary Mode (No Impact) at low speed to penetrate the glazed surface. Switch to Hammer/Impact mode only after reaching the backing concrete layer to prevent cracking the tile.
- Verify Installation: Ensure the 6.35 mm hex shank is fully seated and locked into your tool's chuck before operation.
- Vertical Pressure: Maintain a strictly perpendicular (90°) angle relative to the surface and apply steady forward pressure without forcing the bit sideways.
- Cooling Intervals: During prolonged drilling in hard materials, periodically pull the bit out to evacuate dust; water cooling can be applied to protect the carbide tip from overheating.
- Daily Maintenance:
- Clear Residue: Clean off all tile dust and concrete debris from the bit surface and spiral flutes after each use.
- Rust Prevention: Apply a thin layer of protective anti-rust oil and store the tool in a dry, well-ventilated area.
