Engineering Dimensions & Geometry
| Parameter | Value | Tolerance |
|---|---|---|
| Nominal Diameter (D) | 24.00 mm | h5 (±0.004 mm) |
| Overall Length (L) | 192.0 mm | ±0.50 mm |
| Flute Length (L_f) | 132.0 mm | ±0.30 mm |
| Point Angle | 135° | ±1° |
| Helix Angle | 35° | ±2° |
| Shank Diameter | 24.02 mm | h6 |
| Corner Radius | 0.03 mm | ±0.01 mm |
Grade Details - Key Grade Characteristics
The TA grade substrate is a micro-grain tungsten carbide (WC-Co) with a grain size of 0.5–0.8 μm, providing an optimal balance between hardness and toughness. The TiAlN multi-layer PVD coating enhances surface hardness to approximately 3,300 HV while maintaining a low coefficient of friction (0.35–0.45 against steel).
- Hardness: 1,650 HV ( substrate) / 3,300 HV (coated)
- Transverse Rupture Strength: 3,800 MPa
- Coating Thickness: 2.5–3.5 μm
- Oxidation Resistance: Up to 900°C
- Coating Adhesion: HF1 (Rockwell C adhesion test)
Grade Comparison Matrix
| Grade | Hardness | Toughness | Best For |
|---|---|---|---|
| TA | ★★★★☆ | ★★★★☆ | General purpose, high-speed drilling |
| TB | ★★★★★ | ★★★☆☆ | Hardened steels >50 HRC |
| TC | ★★★☆☆ | ★★★★★ | Interrupted cuts, unstable setups |
| TD | ★★★★☆ | ★★★★☆ | Stainless steel & superalloys |
Chipbreaker Profile
The R features an optimized chipbreaker geometry with a polished flute surface (Ra 0.2 μm) and a specially designed land width that promotes efficient chip curling and evacuation. The 35° helix angle ensures smooth chip flow along the flute, minimizing the risk of chip packing in deep-hole applications. A margin relief of 0.08–0.12 mm reduces friction against the hole wall, lowering heat generation and extending tool life by up to 25% compared to standard geometries.
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Suitability |
|---|---|---|
| Tool Steel | P.1–P.3 | ★★★★★ Excellent |
| Hardened Steel (up to 45 HRC) | M.1–M.2 / K.1–K.3 | ★★★★☆ Very Good |
| Gray Cast Iron | K.2–K.3 | ★★★★☆ Very Good |
| Ductile Cast Iron | K.4–K.5 | ★★★☆☆ Good |
| Aluminum & Alloys | N.1–N.3 | ★★★☆☆ Good (reduce speed 20%) |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Use peck cycle for depths >3xD |
| Stack Drilling | ★★★☆☆ | Ensure clamping rigidity |
| Cross-Hole Intersection | ★★★☆☆ | Reduce feed by 30% at intersection |
| Engraving / Spotting | ★★☆☆☆ | Not recommended; use dedicated spot drill |
Recommended Cutting Conditions
| Parameter | Carbon Steel | Stainless Steel | Cast Iron |
|---|---|---|---|
| Cutting Speed (Vc) | 70-110 m/min | 49-77 m/min | 84-132 m/min |
| Feed per Rev (f) | 0.18-0.35 mm/rev | 0.14-0.28 mm/rev | 0.18-0.35 mm/rev |
| Spindle Speed (n) | 2000-3500 rpm | 1400-2450 rpm | 2200-3850 rpm |
| Coolant | Emulsion 6–8% | Emulsion 8–10% + EP additives | Dry or compressed air |
Operating Guidelines
- Peck Cycle: For depths exceeding 3xD, use a peck depth of 1–1.5xD with full retraction to clear chips.
- Coolant Pressure: Maintain minimum 20 bar (290 psi) internal coolant pressure for optimal chip evacuation in deep holes.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent chipping of the cutting corner.
- Tool Overhang: Minimize overhang to 4xD or less. Use hydraulic or shrink-fit chucks for best rigidity.
- Pre-Drilling: For cast iron or welded structures, consider a pilot hole 0.2 mm smaller to guide the drill.
- Tool Life Monitoring: Replace when flank wear exceeds 0.15 mm or when burr formation on the hole exit increases.
Toolholder Compatibility
| Holder Type | Compatibility | Runout (TIR) |
|---|---|---|
| Hydraulic Chuck (Hydro) | ★★★★★ Recommended | < 0.003 mm |
| Shrink-Fit Chuck | ★★★★★ Recommended | < 0.003 mm |
| Precision Collet (ER16–ER32) | ★★★★☆ Acceptable | < 0.010 mm |
| Weldon Side-Lock | ★★★☆☆ Not Recommended | > 0.020 mm |
