Types of Metal Drill Bits
Drill Bit Sets
Good for daily use on site or in the shop. These sets come pre-organized in indexed cases and feature high speed steel bits made for drilling into wood, mild steel, aluminum, and plastic. The value here is in the versatility. You get a full spread of fractional sizes in a compact, dependable kit that covers your basics without overcomplicating things.
M2 HSS Black Oxide Drill Bits
Made from rugged M2 high speed steel and finished with black oxide to reduce friction and heat. These bits are good for repetitive drilling in low to medium hardness metals. The coating helps retain cutting fluid and improves bit life without the cost of a cobalt upgrade. A workhorse in general metal fabrication, assembly, and shop environments.
M2 HSS Black And Gold Drill Bits
These bits feature the same M2 core with a dual black and gold oxide finish for better wear visibility and increased resistant to edge dulling. You'll notice smoother entry, cleaner chip flow, and longer intervals between bit replacements. A solid choice for shop techs or anyone who values consistency and performance during repeated use.
M35 Cobalt Drill Bits
Designed to push through stainless, alloy steels, and tougher materials. With 5 percent cobalt content, these bits resist dulling and overheating even when you're drilling under pressure. They're a staple in machine shops and maintenance departments where Standard HSS just doesn't hold up.
M42 Cobalt Double Ended Drill Bits
Twice the value, zero downtime. These M42 bits include 8 percent cobalt and two cutting ends on a single shaft, giving you double the service life with fewer tool changes. When you're on a deadline or drilling nonstop, that makes a difference. These are good for high-volume fabrication or repair jobs where bit swaps slow things down.
M42 Cobalt Spot Weld Drill Bits
Specifically engineered for removing spot welds in body shops, frame work, or panel replacement jobs. The cutting point is ground for precision entry and minimal distortion. The M42 cobalt base delivers durability under repeated heat and pressure, exactly what you need when separating joined steel sections without tearing into what's underneath.
M2 HSS Step Drill Bits
Built for drilling clean holes through electrical panels, sheet metal, and switch boxes. The step design lets you move through multiple hole sizes without changing the bit. Made from M2 steel for toughness, these are a favorite in electrical, HVAC, and service truck setups where speed and flexibility matter.
Metal Drill Bits Available Finishes
South Coast Fasteners offers drill bits with performance-focused finishes that help reduce friction, improve chip evacuation, and extend the usable life of each bit.
Black Oxide
A classic finish that helps reduce rust and friction during cutting. Its especially helpful when using cutting oils or drilling dry through mild steel or sheet metal. This finish is found on most of our general-purpose HSS bits because it strikes the right balance of performance and price.
Black and Gold Oxide
A layered oxide finish that's as practical as it is visible. The gold section gives you a fast visual cue when bits start to dull, while the black helps reduce surface friction and maintain smooth cutting. A step up from basic black oxide when you're drilling longer or want to track tool life more closely.
