The integrated coolant system combined with dry drilling innovation extends bit life. Sizes included range from 3/16″ to 1/2″. Ideal for projects needing accuracy without wet drilling complications.
Buying Guide for Drill Bits to Use on Hard Stone
Selecting the best drill bit for hard stone depends on several factors to ensure efficiency, durability, and clean results. Here are important considerations:
Material Composition
- Carbide Tips: Durable and resistant to wear, carbide tips work well for most masonry and tile drilling applications.
- Diamond Coating: Ideal for extremely hard surfaces like granite, porcelain, and marble. Provides exceptional precision and longer bit life.
- Tungsten Steel M35: High-speed steel alloy with added toughness, suitable for various materials including concrete and stone.
Drilling Method Compatibility
Check whether the drill bits are compatible with your drill type—rotary drills, hammer drills, or bench drills—and whether they support dry or wet drilling. Wet drilling can prolong bit life but requires water supply, while modern dry drill bits often include cooling lubricants.
Size Range and Versatility
Choose drill bit sets that offer a wide range of sizes to handle different hole diameters. Versatile sets are beneficial for multiple projects involving tile, brick, glass, or wood.
Design Features
- Groove Design: U-shaped or double U-type grooves facilitate dust and chip evacuation, improving speed and preventing overheating.
- Shank Type: 3-flat shanks or round shanks with secure locking ensure tight gripping and minimize slippage.
- Special Shapes: Eccentric or skewed cutter heads improve drill bit penetration in challenging conditions like deep or angled holes.
Durability and Maintenance
Look for bits with surface treatments or coatings that reduce corrosion. Diamond-coated and tungsten steel bits generally require less frequent replacement. Follow recommended cooling intervals when dry drilling to extend life.
Application Specifications
Consider what materials you will primarily drill. For hard stone or granite, diamond drill bits are usually the best. For general masonry, carbide tipped bits provide good value and performance.
