Recommended Machining Conditions for SCD-AH5 Solid Carbide Drills
Cutting Speed Feed vs. Drill Diameter (mm/rev)
ISO Material Hardness Material No. Vc (m/min) Ø3-5 Ø5.1-8 Ø8.1-12
Hardened steel 50-55 HRc 38 25-40 0.04-0.07 0.05-0.08 0.06-0.10
H Hardened steel 56-60 HRc 39 15-25 0.03-0.06 0.04-0.07 0.05-0.08
Hardened steel 61-70 HRc 39 10-15 0.02-0.04 0.03-0.05 0.03-0.05
Materials over 50 HRc must be used with external cooling while machining.
Use of semi-synthetic or emulsion with more than 6% oil concentration is highly recommended to extend tool life and hole quality.
