Engineering Dimensions & Geometry

Grade Details – Key Grade Characteristics

The PR1725-TX grade represents Kyocera's advanced carbide technology, specifically formulated for stainless steel & hard materials machining:

• Coating System: AlCrN (TX Series) — provides exceptional thermal barrier properties and oxidation resistance up to 1000°C.
• Substrate: Sub-micron carbide matrix ensures high transverse rupture strength and resistance to micro-chipping.
• Hardness: 93.0 HRA — maintains cutting edge integrity at elevated speeds.
• Coating Color: Dark Grey — visual identification for grade verification.
• Friction Coefficient: Reduced by 25% compared to uncoated substrates, minimizing built-up edge and extending tool life by up to 40%.

Grade Comparison Matrix

Chipbreaker Profile

The SGS66454 features an optimized point geometry with advanced web thinning and margin design to enhance chip formation and evacuation:

• Point Geometry: Self-centering 140° split point with reinforced chisel edge for reduced thrust forces.
• Flute Profile: Parabolic flute design with polished surface (Ra 0.2 µm) to prevent chip packing in deep-hole applications.
• Margin Treatment: Dual-margin configuration with honed edges (0.02 mm × 20°) stabilizes the tool in the cut and improves hole cylindricity.
• Chipbreaker Style: Continuous spiral chipbreaker with variable pitch to suppress harmonic vibration and ensure smooth chip curling.

Recommended Applications & Workpiece Materials

Application Map by Operation

Recommended Cutting Conditions

Parameters below are starting recommendations for stable CNC environments with internal coolant supply (≥ 70 bar recommended for 3xD drills):

Note: Reduce Vc by 15% when drilling stacked plates or cross-hole intersections. Increase feed by 20% for piloted drilling operations.

Operating Guidelines

• Peck Cycle: For 3xD drills, use peck depth of 1.5–2.0×D in steels; 2.5–3.0×D in aluminum. Full retract every 3–4 pecks to clear chips.
• Coolant Pressure: Minimum 30 bar internal coolant for holes > 3×D; 70+ bar recommended for uninterrupted production.
• Tool Overhang: Keep L/D ratio ≤ 5 for best results. If unavoidable, reduce Vc by 10% and increase feed by 5% to stabilize.
• Entry Angle: Ensure perpendicular entry within ±1°. Use spot drill or chamfer if drilling on inclined surfaces > 5°.
• Spindle Runout: Verify spindle TIR < 0.01 mm at tool tip. Excessive runout accelerates corner wear and reduces hole tolerance.
• Re-sharpening: Not recommended. These solid carbide drills are designed as disposable tools; re-sharpening voids dimensional guarantees.
