* D1<20mm to DIN 6537K NOTE: Solid Carbide Drills from WIDIA in short and regular lengths conform to DIN 6537. D1>20mm to factory standard Drills with long lengths conform to WIDIA factory standard. ** To factory standard Solid Carbide Drills with diameter D1>20mm (not DIN 6537) are also standardised to factory standard.

Tolerances of Drills and Holes μ m +55 +50 High-performance solid carbide drills with tolerances of m7 create holes with +45 tolerances of H9. H8 can be achieved in very good conditions. The drill should be used for holes in H8, and in favourable conditions, H7 can be achieved. +40 Solid carbide drills with H7 create holes in K9–K11. Other drilling tolerances +35 require special solid carbide drill versions. +30 +25 +20 Tolerances of diameter D1 on: +15 Spiral Flute TDG Drill +10 +5 0
