Where this product is used
- General drilling across the materials rated for D101 Silver Bullet drills.
- Materials rated Optimal for the D101: non-alloy steel, about 0.15 %C, annealed; non-alloy steel, about 0.45 %C, annealed; low-alloy steel (under 5% alloying elements), annealed; and wrought aluminium and magnesium alloys.
Finish
Bright (uncoated). The bright finish is for general-purpose applications.
Cutting speeds and feeds
Cutting speeds (Vc) and feed numbers are given for the D101. Speed (rpm) = Vc × 1000 ÷ (π × Ø); treat these as starting values.
