Where this product is used
- General drilling across the materials rated for D102 Blue Bullet drills.
- Materials rated Optimal for the D102: non-alloy steel, about 0.15 %C, annealed; non-alloy steel, about 0.45 %C, annealed; non-alloy steel, about 0.45 %C, quenched and tempered (250 HB); non-alloy steel, about 0.75 %C (annealed and quenched and tempered); low-alloy steel (under 5% alloying elements), annealed; low-alloy steel, quenched and tempered (275 to 350 HB); and high-alloy and tool steel.
Finish
Blue (steam oxide). The blue steam-oxide finish is for ferrous metals: it helps prevent chip build-up on the cutting edges (especially in carbon steels), the oxide layer protects the surface and it carries lubricant well.
Cutting speeds and feeds
Cutting speeds (Vc) and feed numbers are given for the D102. Speed (rpm) = Vc × 1000 ÷ (π × Ø); treat these as starting values.
