SAMHO HRC65 Solid Carbide Drill Bits – Precision Drilling (3D / 5D Options)

Designed for precision drilling in materials up to HRC65, the SAMHO Solid Drill Series is the ultimate choice for high-speed, high-efficiency machining without the need for internal coolant systems. Featuring a robust 140° point angle and ultra-fine grain carbide substrate, these bits deliver exceptional positioning accuracy and wear resistance in tool steel, mold steel, and heat-treated alloys.

Hardness Mastery: Optimized for HRC46 to HRC68 applications.

Cooling Versatility: Engineered for dry machining and MQL (Minimum Quantity Lubrication) environments.

Dual Depth Options: Available in 3×D and 5×D length-to-diameter ratios.

Precision Ground: 5-axis CNC manufactured for perfect concentricity.

When your machining setup doesn’t support through-spindle coolant, you need a drill bit that can handle the heat. The SAMHO HRC65 Solid Series provides a cost-effective, high-durability solution for drilling hardened steels, ensuring consistent hole quality and long tool life under demanding dry-cutting conditions.

Key Features & Technical Benefits

  • Ultra-Fine Grain Carbide for Extreme HRC65 Hardness
    Unlike standard bits, SAMHO drills are manufactured from a high-density ultra-fine grain carbide substrate. This material offers the perfect balance of fracture toughness and hardness, allowing the tool to maintain a sharp cutting edge even when drilling heat-treated materials up to HRC65.
  • 140° Point Geometry – “No-Walk” Accuracy
    Precision begins the moment the tool touches the workpiece. Our 140° split point design offers:
    • Superior Self-Centering: Minimizes tool walking and eliminates the need for pilot holes in many scenarios
    • Lower Axial Thrust: Reduces the load on your CNC spindle while maintaining high penetration rates
    • Improved Surface Finish: Ensures clean entry and exit for tight-tolerance holes
  • Reliable Solid Structure (No Internal Coolant Required)
    Specifically designed for machines using external cooling or MQL. This solid structure provides:
    • Increased Tool Rigidity: A solid core offers higher resistance to deflection than hollow coolant-fed drills
    • Cost-Efficiency: Premium performance without internal coolant channels
    • Maintenance-Free: No risk of clogged coolant holes in abrasive materials
  • 5-Axis CNC Precision Grinding
    Every drill in the SHD Series is ground on advanced 5-axis CNC machines. This ensures every flute, land, and point geometry is perfectly consistent, providing the repeatability necessary for high-volume production lines
