Engineering Dimensions & Geometry
Grade Details - Key Grade Characteristics
| Property | Specification | Performance Impact |
|---|---|---|
| Carbide Grain Size | Ultra-fine grain tungsten carbide (0.5 μm) | Higher toughness and edge stability at elevated speeds |
| Coating System | AlTiN (Aluminum Titanium Nitride) PVD multi-layer | Superior heat resistance up to 900°C; reduced built-up edge |
| Hardness | HRA 92.5 ± 0.5 | Excellent wear resistance in abrasive materials |
| Transverse Rupture Strength | ≥ 4,000 MPa | Resists chipping in interrupted cuts and cross-hole drilling |
| Recommended Environment | High-speed drilling, wet & dry machining | Flexible coolant strategies without compromising tool life |
Grade Comparison Matrix
| Grade | Substrate | Coating | Hardness | Primary Use Case |
|---|---|---|---|---|
| TC (This Tool) | Ultra-fine WC | AlTiN PVD | HRA 92.5 | Steel, Stainless, Cast Iron |
| PR1535 | Fine WC | TiAlN | HRA 91.8 | General-purpose steel machining |

Chipbreaker Profile
The #40 TC drill utilizes a MF (Medium Feed) chipbreaker geometry engineered for the nominal diameter range. The flute profile incorporates a variable helix design with polished rake surfaces to minimize friction and promote efficient chip curling and evacuation.
| Parameter | Value | Function |
|---|---|---|
| Chipbreaker Type | MF (Medium Feed) | Optimized chip segmentation for #40" diameter |
| Rake Angle (γ) | 8° ± 2° | Balances edge strength with cutting efficiency |
| Flute Surface Finish | Ra 0.2 μm | Reduces chip adhesion and heat generation |
| Core Thickness | 0.22 × D1 | Maximizes rigidity while maintaining coolant flow |
Recommended Applications & Workpiece Materials
- Carbon & Alloy Steels (≤ 45 HRC): Excellent chip control and surface finish in 1045, 4140, 4340 grades
- Stainless Steels: Austenitic (304, 316) and martensitic (410, 420) series with reduced built-up edge tendency
- Cast Iron: Gray cast iron (Class 30-40) and ductile iron (65-45-12) with high wear resistance
- Titanium Alloys: Ti-6Al-4V at moderate speeds with adequate coolant delivery
- High-Temperature Alloys: Inconel 718 and Hastelloy at reduced parameters with rigid setup
Application Map by Operation
| Operation Type | Suitability | Recommended Conditions | Expected Tool Life |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Standard parameters per cutting data | High |
| Blind-Hole Drilling | ★★★★★ Excellent | Reduce feed 10% in last 2×D; use peck cycle | High |
| Cross-Hole Intersection | ★★★★☆ Very Good | Reduce speed 15%, rigid toolholder required | Moderate-High |
| Stacked Plate Drilling | ★★★★☆ Very Good | Consistent entry/exit with clamping pressure | Moderate-High |
| Micro-Peck Drilling | ★★★☆☆ Good | Peck depth 0.5×D for holes >3×D deep | Moderate |
Recommended Cutting Conditions
| Workpiece Material | Hardness | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|---|
| Low-Carbon Steel | < 200 HB | 88-132 | 0.08-0.14 | Wet/Dry* |
| Medium-Carbon Steel | 200-280 HB | 80-120 | 0.05-0.12 | Wet preferred |
| Alloy Steel | 280-350 HB | 68-102 | 0.06-0.12 | Wet required |
| Stainless Steel (Austenitic) | < 250 HB | 60-90 | 0.07-0.13 | Wet required |
| Cast Iron (Gray) | 180-260 HB | 80-120 | 0.10-0.18 | Wet/Dry |
| Titanium Alloy Ti-6Al-4V | < 350 HB | 40-60 | 0.05-0.10 | Wet required |
*Dry machining requires stable machine spindle and rigid workholding. Adjust parameters based on machine rigidity and hole depth.
Operating Guidelines
- Runout Limit: Maximum tool runout at the cutting edge should not exceed 0.01 mm (0.0004") to prevent uneven wear and premature failure.
- Pecking Cycle: For holes deeper than 3×D, implement a peck cycle with retract to clear chips. Peck depth = 1.0×D for <5×D holes, 0.5×D for >5×D holes.
- Coolant Pressure: Minimum 70 bar (1,000 psi) through-tool coolant recommended for holes >3×D in stainless and titanium.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent chipping on inclined surfaces.
- Tool Overhang: Minimize overhang to 4×D or less. Use hydraulic or shrink-fit holders for optimal rigidity.
- Speed/Feed Ramp: Reduce feed by 30% for the first 1 mm of entry to stabilize the tool before full engagement.
Toolholder Compatibility
