METAL DRILL SET MILWAUKEE HSSG-CO PO 25PCS

Highly heat-resistant metal drill bits made from 5% cobalt-alloyed high-speed steel according to DIN 338 standard, ground to precision. Suitable for drilling high-alloy steels and metals with tensile strength exceeding 1000 N/mm² (e.g., stainless steel). QUAD EDGE tip: 135° cutting point and four chisel edges improve centering, enable faster drilling initiation without bit walking, and produce less chip volume, preventing heat buildup. Variable body geometry removes material faster from the steel, helping the tip stay cooler. Improved tapered shank: wider core toward the drill bit shaft enhances drill bit durability. Three-flute shank from 5 mm diameter upward improves grip and prevents bit slippage. Color: bronze. ? 1 / 1.5 / 2 / 2.5 / 3 / 3.5 / 4 / 4.5 / 5 / 5.5 / 6 / 6.5 / 7 / 7.5 / 8 / 8.5 / 9 / 9.5 / 10 / 10.5 / 11 / 11.5 / 12 / 12.5 / 13 mm.
