slot-cutting-drill-bit-for-metal-80 Short-Length Drill Bits. Drill Bits for Precise Holes. 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. As a low-carbon steel, stainless steel has a natural hardness that comes without traditional hardening. Carbide Drill Bits for Precise Holes. That matters once you realize cobalt drill bits cost significantly more than other types of twist drill bits.

You get the same great case. The trade-up is cost. We have great news for anyone looking for the best drill bits for stainless steel. The same bits you use on hardened steel work on stainless. Hardened steel is a medium of high-carbon steel that gets heat-treated, quenched, and finally tempered. As a low-carbon steel, stainless steel has a natural hardness that comes without traditional hardening. Drilling stainless takes a strong bit—the same cobalt bits we recommend above.

With that said, stainless can actually harden up as it heats—so drilling slowly often helps you get through the material more efficiently. Use cutting oil or similar lubricant when drilling into stainless and apply enough pressure to see a steady removal of material. Even the best drill bits for stainless steel heat up over time, so be prepared to monitor heat buildup. Listed in our best drill bits article, Milwaukee Red Helix cobalt bits use a variable flute design that clears away debris quickly.

How quickly? Their unique design not only helps them drill efficiently, but it also aids in cooling. The trade-off is that these bits thin out more towards the tip. However, they also extended the flutes lower towards the shaft. The result is a more compact bit with a similar drilling depth. We love how quickly these bits drill and also how well they remove steel in tight, efficient spirals. The combination of the unique cutting head and the flute design landed these as our best drill bits for steel—particularly carbon steel.

Thanks to the cobalt steel blend, plan on sharpening these when the tips grow dull from use. The value of this kit makes these the best drill bits for steel. We love the build quality on the DeWalt cobalt pilot point drill bit set. It has a tapered core that gradually adds stiffness to the bit as it gets closer to the base. Sometimes you need to drill through steel…but that steel is buried in concrete. We like the design better than Bosch Rebar Cutters because you use the same bit to drill the hole and penetrate the rebar.

With Bosch, you drill using rotary hammer mode, switch to the Rebar Cutter in rotary-only mode, and then return to your original bit to finish the hole. These bits drill quickly through concrete then continue right through rebar.

As we mentioned above, Bosch Rebar Cutter bits present a viable option, but they slow you down when working. These bits should last a good while since they only cut the metal of rebar, but we prefer a single cutting solution overall. Shop Bosch Rebar Cutters here. It can tackle stainless steel and certainly anything softer or milder than that. 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.

The cobalt blend gives these bits a much longer life. Since step bits are both expensive and extremely difficult to sharpen, we like them to last as long as possible.

Irwin gives these bits a Speedpoint tip. It helps get the hole started quickly and reduces wandering. 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.

Several step bits make for viable solutions for electricians and others looking to drill through sheet metal and thicker materials. While we favor the Irwin Cobalt models above, the dual-fluted Milwaukee Step Bits come in handy configurations to tackle common job site needs. Diablo step bits promise twice the cutting speed and up to 6X longer life. They attribute this, in part, to a precision CNC grinding process. 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.

For metal drilling, we definitely put these as the bare minimum. With titanium nitride, you have to remember it only coats the bit. As the coating wears off the cutting edges, you pretty much have to replace them. That also means you can sharpen them before having to replace them.

This helps save money when you buy these more expensive bit sets. Cobalt bits are our go-to for drilling through metal—particularly hardened steels and stainless steel. We probably missed something along the way—we get it. At some point we have to draw the line and finish the article. With that said—let us know what you think the best drill bits for metal are.
