Lichamp 21-Piece HSS Cobalt Drill Bit Set (1/16" to 3/8") – M35 High-Speed Steel, 3-Flute Design for Drilling Hard Metals & Cast Iron – Includes Metal Case
M35 Cobalt Steel for Durability: Made from HSS M35 with 5% cobalt, offering enhanced hardness, heat resistance, and wear, ideal for medium to hard metals like cast iron and mild steel
3-Flute Design for Faster Chip Removal: The patented 3-flute design clears chips 150% faster, reducing heat buildup and improving efficiency, especially in softer metals and alloys
Best for Tougher Metals with Proper Technique: Ideal for mild steel, cast iron, and alloys. For stainless steel (up to 3mm thick), use slow speeds and light pressure. Smaller bits perform best on materials 1-2mm thick for optimal results
Smooth & Accurate Drilling: The 135° split point reduces bit walking, allowing for quicker starts and cleaner holes in softer metals and general use
Complete 21-Piece Set with Case: Includes drill bits from 1/16" to 3/8" (3-flute and 2-flute), plus a metal storage case for easy organization and quick size identification
