Because of rust and stain resistance, good luster, and low maintenance, it has many commercial uses including cookware, cutlery, home appliances, construction fasteners, and surgical instruments. The bits feature the expected 135° split point, which gives you a nice, steady, and productive drilling speed.
The round case makes it simple to remove the exact bit you need. They did very well in steel and kept a sharp edge after drilling many holes.
If you plan on drilling hardened metal or steels, we love the Irwin 29-piece M-42 Cobalt bit kit as our the best metal drill bit set. Irwin actually sells an M35 cobalt set if you don’t plan to drill hardened steel.
Overall, this kit gives you the best drill bits for metal applications of all kinds. They make these bits with M42 cobalt steel, so they drill really well without heating up quickly.
They also seem to hold an edge and stay sharp even after dozens of drilled holes. The round case makes it simple to remove the exact bit you need.
Use cutting oil or similar lubricant when drilling into stainless and apply enough pressure to see a steady removal of material. Listed in our best drill bits article, Milwaukee Red Helix cobalt bits use a variable flute design that clears away debris quickly.
Their unique design not only helps them drill efficiently, but it also aids in cooling. The result is a more compact bit with a similar drilling depth.
Thanks to the cobalt steel blend, plan on sharpening these when the tips grow dull from use. Dealt Industrial Cobalt Pilot Point Drill Bits We love the build quality on the Dealt cobalt pilot point drill bit set.
Bosch Rebar Cutter SDS-Max Bits As we mentioned above, Bosch Rebar Cutter bits present a viable option, but they slow you down when working. The Milwaukee Hole Dozen with Carbide Teeth really wins for metal drilling.
These are the best hole saws for metal drilling that electricians, HVAC, and/or MRO Pros can use. Because they work effectively in both metal and wood, any Pro looking for a general-purpose set of hole saws should quickly fall in love with their productivity.
It vastly outperforms bi-metal blades and tackles those materials carbide wood hole saws can’t (or shouldn’t) touch. Our team grabs Irwin Unibit Cobalt Step Bits for any quick thin metal drilling applications.
Since step bits are both expensive and extremely difficult to sharpen, we like them to last as long as possible. We also have to admit these became our best step bits for metal in part because Irwin laser-etched the measurements right on the inside of the flute.
While we favor the Irwin Cobalt models above, the dual-fluted Milwaukee Step Bits come in handy configurations to tackle common job site needs. Drill bits made with a Titanium nitride coating resists corrosion and friction.
It beats black oxide in that it increases surface hardness and does a better job reducing heat while drilling through metal. Since the cobalt is blended into the steel, it doesn’t wear away like a titanium or black oxide coating.
We know personal preferences take a front seat in determining the best drill bit, and every Pro is different. Do Pro Tool Nation a favor and tell us what your top pick is and why you love it.
Our Pro reviewers work in the trades and have the skills and experience to know whether tools can perform well in the field. Our team will put our hands on hundreds of additional tools at media events and trade shows throughout the year.
We consult with innovators in the technology and design of tools to gain a broader grasp of where these products fit and how they work. We work with more than two dozen professional contractors around the United States who review products for us on real job sites and consult with us on testing methods, categories, and weighting.
An alloy, with at least 10.5 percent chromium and available in several grades, stainless steel is popular because of its low maintenance, high sheen, and resistance to stains and rust. Drill bits built to work on softer material, like wood, won’t do the trick against stainless steel.
Luckily, manufacturers purpose-design special drill bits capable of puncturing even the hardest grade of stainless steel. The BEST OVERALL: IRWIN Drill Bit Set, M35 Cobalt Steel, 29-Piece the BEST BANG FOR THE BUCK: Seiko 10193A Titanium Step Drill Bit Set BEST UPGRADE: 230 Pieces Titanium Twist Drill Bit Set MOST DURABLE: Honor Metric M35 Cobalt Steel BEST FOR HOBBYISTS: Bosch CO14B 14 PC.
Read on to learn the factors to consider as you search for the best drill bits for your projects that involve stainless steel. One way that manufacturers achieve this hardness is by infusing materials that facilitate penetration and protect against overheating.
Titanium and tungsten carbide are nearly as hard as diamond, making them ideal for penetrating steel. They incorporate an element with between 5 percent and 8 percent cobalt that makes the drill bit harder than a typical HSS bit and thus suitable for precision drilling in stainless steel and other hard materials.
Black oxide also protects against corrosion and water, keeping the drill bits functional for a longer period of time. The coating provides the ancillary benefit of being ultradurable, making them an excellent value for consumers who intend high-frequency use.
Individuals who intend to drill stainless steel frequently should be sure to buy bits designed with longevity in mind. Our top picks are based on their ability to effectively drill stainless steel, in addition to their durability, construction, and precision.
Read on to discover some of the best drill bits for stainless steel to ensure they are the right fit for your next project. A rubber-reinforced carrying case protects the drill bits from accidental drops and makes organization and transportation a snap.
For the precision steelworker with budget considerations, Seiko packs a lot of punch into a 3-piece drill bit set. The 135-degree split point tip starts drilling at contact, reducing friction, pressure, and heat.
These bits are constructed from high-speed steel with a titanium nitride coating that facilitates penetration and protection from heat and high-rotation operation. In addition to stainless steel, they perform well on aluminum, zinc, wood, and other materials; the 135-degree split point tips facilitate penetration and decrease the force required to drill.
The spiral flute clears shavings during drilling, and the split-point tip eases penetration and keeps the heat at lower levels. With proper maintenance and storage, these drill bits are likely to outlast even the most stubborn materials.
This set is compact with surface-hardened tips designed to penetrate stainless steel, and the quality construction ensures years of service to even the most fervent hobbyist. Though drill bits for stainless steel pull heavier duty, they are also made of more durable materials.
