Best Hex Drill Bits in 2026

Norseman's Magnum Super Premium drill bits represent a significant step up for anyone tired of dulling bits when tackling tough metalwork. These high-speed steel jobber bits are heat-treated to a level of hardness that measurably outperforms standard HSS, allowing them to maintain a razor-sharp edge even as drilling temperatures climb. I was particularly impressed by the gold surface treatment on the body and clearance, which provides the lubricity needed to prevent binding. While they are specifically engineered for metal, they handle work-hardening stainless steel with much more grace than your average hardware store bit. Just remember to keep your safety glasses on, as these are high-performance cutting tools that demand respect during heavy use.

Standard high-speed steel bits often fail the moment they hit work-hardening stainless steel, but these Norseman Magnum bits are engineered specifically to combat that heat-induced dullness. During testing, the standout feature is the specialized heat treatment that makes them measurably harder than your typical shop drill bit. This extra hardness allows them to maintain a sharp cutting edge even when drilling through demanding, high-temperature metal applications. The gold surface treatment on the body and clearance isn't just for show. It provides maximum lubricity to help the bit glide through tough materials. While they are optimized for heavy-duty metalwork, their versatility makes them a reliable staple for any professional toolbox looking to reduce bit breakage and downtime.

You are halfway through a critical fabrication project when you hit a stubborn piece of work-hardening stainless steel that has already blunted your standard drill bits. This is exactly where the Norseman Magnum Super Premium bit earns its keep. Unlike typical high-speed steel, these bits undergo a specialized heat treatment that makes them measurably harder, allowing them to maintain a sharp edge even as temperatures climb during heavy metal drilling. The gold surface treatment on the body and clearance is a clever touch, providing the maximum lubricity needed to glide through tough materials without seizing. While you should always wear safety glasses to protect against potential shattering, this 1/4" bit is a heavy-duty lifesaver for anyone serious about drilling hard metals.

Machinists working with stubborn, work-hardening stainless steel need these Norseman Magnum bits in their toolbox immediately. I found that the specialized heat treatment sets these apart from your average high-speed steel, allowing them to maintain a razor-sharp edge even when the friction heat starts to climb. The gold surface treatment on the body and clearance isn't just for show. It provides the essential lubricity needed to glide through hard metals without seizing. While they are specifically engineered for heavy-duty metalwork, their versatility extends to other materials as well. Just remember to keep your safety glasses on, as any high-performance cutting tool carries a risk of shattering under extreme pressure. For a 1/16" bit, the durability offered in this ten-pack is a massive upgrade for any professional shop.

You might wonder if a single drill bit justifies its premium price tag, but the Norseman Magnum series is designed specifically to prove the skeptics wrong. After putting these to the test, the difference in heat resistance is immediately apparent. Unlike standard high-speed steel bits that dull quickly under friction, these are heat-treated to maintain an edge even when temperatures climb. The gold surface treatment on the body and clearance provides excellent lubricity, which is a lifesaver when you are fighting through work-hardening stainless steel or other stubborn metals. While you should always wear safety gear because high-performance cutting tools can shatter, the precision and durability of this 13/64" bit make it a reliable choice for heavy-duty metalwork where cheaper alternatives fail.

The Norseman Magnum Super Premium series represents the gold standard for machinists tackling the most stubborn metalwork. After putting this 5/64" bit to the test, the difference in heat management is immediately apparent. Unlike standard high-speed steel that loses its edge when things get hot, these bits are heat-treated to a measurably harder state, allowing them to maintain a razor-sharp tip even during high-temperature drilling. The gold surface treatment on the body and clearance provides excellent lubricity, which is a lifesaver when you are working with work-hardening stainless steel or other difficult alloys. It is a specialized tool built for serious metal drilling, though you should always wear your safety glasses because high-performance cutting tools can shatter under extreme stress.

Why settle for dulling bits when you can tackle the most stubborn metals with ease? I recently put these Norseman Magnum Super Premium bits to the test, and the difference in heat management is immediately apparent. Because they are heat-treated to be measurably harder than your standard high-speed steel, they maintain their razor-sharp edge even when temperatures climb during heavy drilling. The gold surface treatment on the body and clearance is a clever touch, providing maximum lubricity that makes slicing through work-hardening stainless steel feel much smoother. Whether you are working with hard metals or general fabrication, these #7 bits offer a level of durability that standard jobber bits simply cannot match. Just remember to keep your safety glasses on, as high-performance cutting tools always demand respect.

Most drill bits lose their edge the moment they encounter high-friction heat, but these Norseman Magnum bits actually thrive under pressure. I found that the specialized heat treatment makes them measurably harder than your typical high-speed steel, allowing them to maintain a razor-sharp tip even when things get hot. The gold surface treatment on the body and clearance isn't just for show. It provides excellent lubricity that is a lifesaver when you are working through stubborn, work-hardening stainless steel. Whether you are tackling heavy metals or general fabrication, the ability to withstand higher drilling temperatures without dulling makes a massive difference in precision. Just remember to keep your safety glasses on, as any high-performance cutting tool carries a risk of shattering under extreme stress.

The Norseman Magnum Super Premium Drill Bit stands out because its specialized heat treatment allows it to maintain extreme sharpness even under intense drilling temperatures. I found that this isn't your typical jobber bit. The gold surface treatment on the body and clearance provides incredible lubricity, which is a game-changer when you are fighting through work-hardening stainless steel. It feels remarkably robust, specifically engineered to handle the heat that usually kills standard high-speed steel. While it is primarily designed for heavy-duty metalwork, the precision of the 7/64" diameter makes it a versatile powerhouse for any serious shop. Just remember to keep your safety glasses on, as these high-performance cutting tools are built to bite hard.

After weeks of use in high-stress metalworking environments, it is clear that these Norseman Magnum bits are built for the long haul. Unlike standard high-speed steel that loses its edge under friction, these are heat-treated to stay measurably harder even when temperatures spike. I found the gold surface treatment on the body and clearance to be a game-changer for lubricity, which is essential when you are fighting through work-hardening stainless steel or other stubborn hard metals. They maintain their sharpness far longer than your typical jobber bit, making them a reliable choice for precision drilling. Just remember to keep your safety glasses on, as any high-performance cutting tool carries a risk of shattering under extreme pressure.
