3-edge 90 Degree Metal Countersink Chamfering Drill Bit

Core Design & Material Advantages

Premium M2 High-Speed Steel Base Material

• Superior Red Hardness: Maintains cutting edge hardness at temperatures up to 550°C, ensuring long service life in high-speed machining

• Exceptional Wear Resistance: Outlasts standard HSS by 30-50% in continuous chamfering operations, reducing tool replacement frequency

• Ultra-High Precision: Uniform material structure enables ultra-tight tolerances, critical for consistent chamfer angles and finish quality

3-Flute Cutting Geometry (Core Differentiator)

• Smoother, Faster Cutting: 3-flute design delivers more cutting edges per revolution, reducing chatter and vibration for a mirror-smooth finish

• Higher Feed Rates: Enables faster machining speeds than 2-flute countersinks, boosting production efficiency

• Better Chip Evacuation: Optimized flute geometry clears chips efficiently, preventing clogging and heat buildup during deep chamfering

• 90° Included Angle: The universal standard for countersinking screws, bolts and fasteners, compatible with all global industrial standards

Precision Fully Ground Manufacturing

• Ultra-tight concentricity and minimal radial runout for perfectly aligned, consistent chamfers

• Ultra-sharp cutting edges for burr-free, clean cuts in all common metals

• Consistent batch-to-batch performance, critical for automated CNC production lines

Straight Round Shank Design

• Universal Compatibility: Fully compatible with all standard drill chucks, CNC machining centers, lathes and drill presses

• Reinforced Shank Structure: Uniform shank design ensures stable clamping and zero slippage during high-torque chamfering

• Standard Shank Sizes: Available in all common shank diameters for seamless integration with existing tooling
