About this item
  • Efficient Chip Removal & Smooth Operation:The optimized dual-flute geometry with two cutters enables rapid and efficient chip evacuation, preventing clogging and heat build-up. This results in smoother drilling, reduced friction, and protects both the bit and your workpiece.
  • Premium 5% Cobalt M35 Steel for Ultimate Durability：Crafted from genuine 5% cobalt M35 high-speed steel with a hardness of 63 HRC, these bits offer exceptional performance. Their heat resistance, wear resistance, and resistance to chipping are up to 3 times higher than standard HSS drill bits, ensuring a dramatically extended service life under demanding conditions.
  • Precision-Ground 135° Self-Centering Point:Each bit features a precision-ground 135° split point. This design ensures instant, accurate centering upon contact, preventing “bit walking” and skidding. It allows for faster penetration into the workpiece and contributes to cleaner, more precise holes.
  • Professional-Grade for Hard & Soft Materials:Specially engineered for machining challenging materials like stainless steel, cast iron, titanium alloys, and hard plastics. The round shank design ensures compatibility with professional drilling equipment, while its robust construction also makes it effective for wood and softer materials, offering true versatility. 
  • Full-Size Set for Versatile Applications:This comprehensive 19-piece set covers essential sizes from Ø1mm to Ø10mm, ready to handle a wide range of basic to advanced drilling tasks. The included durable plastic storage case keeps your bits organized, protected, and portable.

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.
