4.3mm HSS-E Jobber Drill
Profile Ground for High-Concentricity Production Drilling
Precision Performance
This 4.3mm jobber drill is precision-engineered via profile grinding, ensuring excellent concentricity and pitch accuracy required for high-efficiency production environments. It features an HSS-E (Cobalt-alloyed) construction and a specialized 135° point geometry (shape C), which improves self-centering capability and reduces thrust force during operation.
Key Technical Highlights
- • Material: High-performance HSS-E.
- • Geometry: Shape C point (≥ 2mm) for high accuracy.
- • Point Angle: 135° for easier material penetration.
- • Tolerance: h8 nominal diameter accuracy.
- • Standard: DIN 338.
| Nominal ⌀ (Dc) | 4.3 mm |
| Overall Length (L) | 80 mm |
| Flute Length (Lc) | 47 mm |
| Feed Rate | 0.05 mm/rev (< 900 N/mm²) |
Drilling Guidance
To maintain precision and prevent tool breakage, adhere to the recommended maximum drilling depth formula:
*For this drill, the maximum recommended depth (L₂) is 40.6 mm.
