About this item
- Built for Hard Steel – M35 Cobalt Strength: Made from premium M35 cobalt high-speed steel (5% cobalt), delivering HRC 63–66 hardness and superior heat resistance. Cuts through stainless steel, alloy steel, and other tough metals without dulling or overheating.
- 135° Split Point – No Walking, Faster Starts: Self-centering 135° split point tip prevents slipping on metal surfaces. Drill accurately without pilot holes, saving time while producing clean, precise holes in hard materials.
- One Set, Multiple Materials: Designed for stainless steel, cast iron, alloy steel, and titanium, while also handling aluminum, copper, plastic, and wood with ease. A true all-purpose drill bit set for home, workshop, or jobsite use.
- Multiple Size Sets – Choose What You Need: Available in 5 to 27 piece sets, covering sizes from 1mm to 13mm. Select sets include duplicate sizes for high-wear bits (like 5mm, 6mm, 8mm), giving you longer usability and fewer interruptions.
- Durable Design – Smooth, Cooler Drilling: Fully ground twist design with dual flutes ensures fast chip removal, reducing heat and friction. Hardened through high-temperature quenching for long-lasting performance. Packed in a sturdy storage case for easy organization.

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.
