About this item
  • PACKING LIST: 1 packs of drill bits in 12mm/0.47inch cutting diameter, 250mm/9.84 inch overall length, 73mm/2.87inch flute length, 135° split point tip.
  • FEATURE: Drill bits made of M2 high-speed steel feature high hardness and wear resistance, making them suitable for machining harder metal materials. The extra long straight shank can reach deep into workpieces and confined spaces where standard length drill bits cannot access.
  • APPLICATION: The drills are suitable for high-hardness metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.
  • NOTE: Position the twist drill at 90° to the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. For large holes, start with a guide hole. Use cutting fluid to improve efficiency, extend tool life, and reduce material damage.
  • INSTRUCTION: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. For specific speed and feed rate recommend for common materials, please refer to the details provided on the product page.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
