What materials can I drill with these cobalt bits?
These bits are ideal for hard metals like stainless steel, carbon steel, cast iron, and titanium alloys, thanks to the 5% cobalt content for heat resistance. They're also suitable for drilling plastic, making them versatile for various projects. Just ensure you use appropriate speeds and lubrication for best results on tough materials.
How does the 135° split point help with drilling?
The 135° split point provides precise centring and eliminates the need for a centre-punch, saving you time and effort. Its non-slip design prevents the bit from walking on the surface, which is especially useful on hard metals. This leads to cleaner, more accurate holes every time.
What exact sizes come in this 25-piece set?
The set includes metric sizes from 1mm to 13mm in increments like 1, 1.5, 2, 2.5mm, and so on up to 13mm. You get a comprehensive range that covers most common drilling needs. The metal index case labels each size for easy selection.
Is the storage case durable and organized?
Yes, it comes in a sturdy metal index case that keeps all bits securely stored and organized. Each size is clearly labeled, so you can quickly find the right bit without rummaging. The case also protects the bits from damage during transport or in your workshop.
Are these drill bits precision-made?
Absolutely, they're manufactured to DIN.338 standards, ensuring high precision tolerances and geometric accuracies. This means consistent sizing and shape for reliable performance in professional or DIY use. It's a quality indicator that helps achieve accurate drilling results.
