1. Product Overview

The Kyocera 1.48mm CA515 2-Flute Solid Carbide Micro-Drill (MPN: SGM07882) is engineered for ultra-precision holemaking in demanding CNC environments. Featuring an advanced CA515 substrate with optimized micro-grain structure, this drill delivers exceptional dimensional accuracy, superior surface finish, and extended tool life across heat-resistant alloy applications. Ideal for electronics manufacturing, it ensures repeatable performance in high-volume production settings.

4. Grade Details – Key Grade Characteristics

Grade CA515 is a nano-structured PVD-coated micro-grain carbide specifically developed for micro-drilling operations. Key characteristics include:

  • Substrate: Ultra-fine tungsten carbide (0.5μm grain size) with 12% cobalt binder for maximum toughness.
  • Coating: Multi-layer TiAlN/TiSiN PVD coating (2.5 μm total thickness) providing exceptional heat resistance up to 1,100°C.
  • Hardness: 1800 HV30, ensuring minimal wear rates in heat-resistant alloy.
  • Friction Coefficient: ≤0.35 against steel, reducing built-up edge and extending tool life by up to 40%.
  • Oxidation Resistance: Stable performance in dry and MQL machining environments.

6. Chipbreaker Profile

The SGM07882 features a proprietary SGM-series chipbreaker geometry optimized for micro-scale chip formation:

  • Front Rake Angle (γ): 12° — promotes smooth chip curling and reduces cutting forces.
  • Back Rake Angle (α): 8° — ensures adequate edge strength for intermittent cuts.
  • Chipbreaker Width: 0.518 mm — tuned for 1.48mm diameter to prevent chip clogging.
  • Chipbreaker Depth: 0.118 mm — creates controlled chip fragmentation for reliable evacuation.
  • Edge Preparation: 0.005 mm hone radius (T-land) for micro-edge stability without chipping.

Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece fixturing, and coolant delivery. For 1.48mm diameter, spindle speed (n) = Vc × 1000 / (π × Dc).

10. Operating Guidelines

  • Runout Tolerance: Maintain total indicated runout (TIR) ≤ 0.005 mm at the tool tip to prevent premature breakage in 1.48mm drills.
  • Peck Cycle: For depths exceeding 16.8 mm, use a peck depth of 0.5×D (0.74 mm) with full retract to break chips.
  • Entry Angle: Ensure perpendicular entry (≤0.5° deviation) to avoid uneven loading and chipping.
  • Coolant Pressure: Minimum 20 bar (290 psi) for through-tool coolant; external flood coolant requires 15–20 L/min flow rate.
  • Pre-Drilling: When enlarging, use a pilot hole 0.05–0.10 mm smaller than 1.48 mm to guide the drill.
  • Tool Life Monitoring: Replace when flank wear (VB) reaches 0.08 mm or when hole tolerance exceeds IT8.
  • Storage: Store in original packaging at <60% relative humidity to prevent edge oxidation.
