Excellent for tough metals
These drill bits cut through stainless steel like butter. The extended length was exactly what I needed for my deep frame projects.

Perfect for deep holes
The extended length feature is not just marketing; it genuinely helps reach difficult spots in thick metal assemblies. Very satisfied.

Solid performance
Good set for the price. They handled the hardened bolts on my old table repair without dulling. One bit chipped slightly due to user error, but overall great.

Precise and long-lasting
The 135-degree point angle prevents walking, which is crucial for precision work. Highly recommend for any serious home workshop.

Best investment for metalwork
I have gone through so many standard bits trying to drill into my steel furniture frames. These tungsten carbide ones are a game changer.

Great quality, needs slow speed
Very sharp and durable. Just remember to use a slower RPM setting to prevent overheating on hard iron. Works perfectly otherwise.
Q: What is the maximum thickness of metal these can drill through?
A: Thanks to the extended length design, these bits can effectively drill through materials up to several inches thick, depending on the specific bit size in the set.
Q: Does the set come with a storage case?
A: Yes, the set includes a durable plastic index box to keep each bit organized and protected when not in use.
Q: Do I need to use cooling oil when drilling stainless steel?
A: While not strictly mandatory for short bursts, we highly recommend using cutting fluid or oil to extend the life of the bit and ensure a cleaner cut on stainless steel.
Q: Can these bits be used with a standard handheld power drill?
A: Yes, as long as your drill has a chuck that accommodates the shank size and can operate at variable speeds, these bits are fully compatible.
Q: Are these suitable for drilling into wood or masonry?
A: These are specifically engineered for hard metals. While they might cut wood, it is inefficient, and they are not designed for masonry or concrete.
