Drill Bit Basics – Anatomy and How to Read Any Bit

Understanding your drill bit starts with the basics — knowing what each part does and how to pick the right one quickly.

Key Parts of a Drill Bit:

• Point Angle: Usually either 118° or 135°.
  • 118° is great for general-purpose drilling in wood and metal.
  • 135° is sharper and flatter, perfect for harder materials like stainless steel — it resists walking and lasts longer.
• Flutes: These are the spiral grooves cutting away debris as you drill. More flutes mean a cleaner hole but slower feed rate.
• Shank Types: The part that fits into your drill.
  • Round shank works in most standard chucks.
  • Hex shank offers a better grip, less slipping — great for quick bit changes.
  • SDS shank fits hammer drills for heavy masonry work.
• Coatings: Protective layers that boost durability.
  • Black oxide resists rust and reduces friction—basic but effective.
  • Titanium nitride (gold color) lasts up to 6x longer than HSS, good for light metal and wood.
  • Cobalt (silver-gold) handles heat better — ideal for stainless steel and tough metals.
  • Carbide-tipped bits are super tough, usually for masonry or tile.

Materials Decoded:

• HSS (High-Speed Steel): The standard go-to, good for wood, plastic, and light metal. Budget-friendly and versatile.
• Titanium Nitride (Gold): Coated HSS, great for longer life and cleaner cuts.
• Cobalt: Alloyed steel with 5-8% cobalt, tougher and heat-resistant, best for stainless steel and hard metals.
• Carbide-tipped: Tough enough for concrete and tile, but expensive and brittle.
• cURL Too many subrequests. Surface-treated steel that resists rust and adds friction control.

Pro Identification Hack:

You can often tell a bit’s material by color + tip shape:

• Gold tips = Titanium-coated bits
• Silver/gold shiny = Cobalt
• Matte black = Black oxide

Wood Drill Bits – Clean Holes Without Splintering

When you’re working with wood, the right drill bit makes all the difference in getting clean, precise holes without splintering or tearing. Here’s a quick rundown of the common types and when to use them:

• Brad Point Bits: These are perfect for pinpoint accuracy, especially when drilling holes for shelf pins, dowels, or any task where neat edges matter. The sharp tip keeps the bit from wandering.
• Spade/Paddle Bits: Need fast, rough holes in framing lumber? Spade bits get the job done quickly, though the hole edges won’t be as clean. Great for rough carpentry and electrical work.
• Auger Bits: Ideal for deep, clean holes in thick wood—think running wires or plumbing through studs. The screw tip pulls the bit through, cutting efficiently without slowing you down.
• Forstner Bits: These deliver flat-bottomed pockets, perfect for installing hinges or making concealed fastener holes. They excel at clean, precise cuts in flat surfaces.
• Hole Saws: When you need large diameter holes—like for doorknobs or recessed lighting—hole saws are the way to go. They cut out a clean circle without messing up the surrounding wood.

If you want a reliable, all-in-one kit, check out the vast 13-Piece Wood Master Set. It includes self-centering brad point bits and covers a range of common wood drilling needs, saving you the hassle of buying different bits for every project.

Metal Drill Bits – Cut Steel Like Butter

When working with steel or other tough metals, having the right drill bit is a game changer. Here’s the lowdown on metal drill bits that make your job easier:

• Step Bits: These are perfect for sheet metal. One bit handles multiple hole sizes, saving you from swapping bits constantly.
• Cobalt Bits: Built tough to resist heat, cobalt bits cut through hardened steel and stainless with ease. They last longer when you’re drilling thicker metal.
• Reduced-Shank Bits (Silver & Deming): Need holes over ½ inch in thick metal plates? These heavy-hitters have a smaller shank so your drill can handle larger diameters.

Pro Tip: Always use cutting oil when drilling metal—this can extend your bit’s life up to 300%, reducing heat and friction.

For serious metalwork, I recommend the vast M35 Cobalt 15-Piece Set. It’s designed for automotive and fabrication tasks, tough enough for any job around your shop or garage.

Masonry & Concrete Bits – Hammer Through Brick and Block

When it comes to drilling into brick, block, or concrete, you need the right masonry drill bit to get the job done without slowing down. Carbide-tipped masonry bits are your go-to for standard hammer drill tasks—tough enough to chip through these hard materials without wearing out fast. For heavier work, SDS-Plus and SDS-Max bits fit rotary hammers and deliver serious power, perfect for big projects like concrete walls or footings.

If you’re after larger holes, core bits are the way to go. They handle clean, wide cutouts for plumbing or electrical pipes with ease. For reinforced concrete or stone, diamond core bits are your best bet—they cut cleaner and last longer against tough materials.

Safety first: Always wear dust protection. Silica dust from cutting concrete can be harmful, so a good mask and ventilation are a must.

For a reliable kit, check out the vast SDS-Plus 7-Piece Masonry Kit—built tough to handle all your brick and block drilling needs with ease.

Tile, Glass & Brittle Material Bits

When drilling tile, glass, or other brittle materials, you need the right drill bit to avoid cracks and chips. The best option? Spear-point carbide bits. These are designed for slow speeds and should be water-cooled to keep the material from overheating or breaking, especially on ceramic or porcelain tile.

Quick Tips:

• Higher point angles (135°) are best for hard metals like stainless steel.
• Use lower speeds on metals to avoid overheating.
• Soft materials like wood and plastic work best with 118° point angle bits.
• Masonry bits require hammer action and dust safety gear.

Maintenance & Sharpening Tips

Keeping your drill bits in good shape saves time and money. Here’s what I’ve learned about maintenance and sharpening:

When to resharpen vs replace:

• Resharpen bits if they’re just dull but not chipped or broken. Sharp bits cut faster and cleaner.
• Replace when the tip is damaged, worn down a lot, or if resharpening won’t bring it back to shape.

Easy storage to avoid rust:

• Keep bits dry and in a case, like the vast drill bit sets offer.
• Use silica gel packs or anti-rust strips in your toolbox.
• Wipe bits with light oil if storing long term—this blocks moisture.

How vast’s lifetime warranty helps:

• If your bits break or wear out unexpectedly, vast’s warranty clips replacement costs.
• It’s peace of mind knowing your investment is protected while you work.

Good care means your drill bits will perform better, last longer, and save you money down the road.
