PRODUCT SPECIFICATION
114360 Series TiN-Coated HSS Jobber Drill
Profile Ground for High-Precision Series Production (DIN 338)
Engineered for High Concentricity
The 114360 Series jobber drills are designed for demanding series production. These tools are profile ground to ensure superior concentricity and pitch accuracy. Enhanced with a Titanium Nitride (TiN) coating, they offer increased wear resistance and longer tool life. Starting from size 2.4 mm, the drills feature a specialized Shape C point geometry, optimizing centering and reducing cutting forces.
Key Technical Highlights
- • Material & Coating: HSS core with TiN coating.
- • Geometry: 118° point angle, 35-40° helix angle (Type N).
- • Core Design: Standard core without core taper.
- • Tolerance: h8 nominal diameter accuracy.
- • Standard: DIN 338 compliant.

Drilling Guidance
To maximize tool life and maintain hole precision, observe the recommended maximum drilling depth calculation:
*Example max depths (L₂): Size 1 = 10.5 mm | Size 5 = 44.5 mm | Size 9.9 = 72.2 mm.
