good product

Why did you pick this product vs others?:Look strong

They cut very clean and precise.

Not the best but will do perfectly for normal workload

Son muy prácticas, con gran funcionalidad

Initially sharp, ran extremely dull from first use in mild steel. I use lower rpms, oil and not allowing the bit to heat soak. Still dulled out and did not complete the first use of 1" hole.

For the price you may be hesitant don’t be they are good quality been using them for a couple weeks drilling electric panels and the are still sharp. These are not HF bits
