Material and Finishes for drill bits

● High-Speed Steel (HSS) drill bits are used for drilling wood, light metals, fiberglass and PVC.

● Black oxide-coated drill bits are more durable than standard HSS bits and the coating helps the drill bit resist rust. These are best for hardwood, softwood, PVC, fiberglass and steel.

● Titanium-coated drill bits have reduced friction, require less effort and last longer than black oxide-coated bits. These are best for hardwood, softwood, PVC, fiberglass and steel.

● Cobalt drill bits are used for drilling hard metal and steel. They dissipate heat quickly and are highly resistant to abrasions, making them better for drilling into hard metals than black oxide- or titanium-coated drill bits. When considering a cobalt drill bit vs titanium, cobalt bits are usually the best drill bits for stainless steel.

● Carbide-tipped drill bits stay very sharp over long periods of use and are used mainly for concrete, tile and masonry. These are often the best masonry drill bits for your project.

● Bi-metal drill bits are useful for a range of materials like light metal, wood and PVC; bi-metal drill bits cut fast and smooth with greatly reduced vibrations.

● Diamond drill bits are ideal for cutting into glass, sea glass, fused glass, rocks and minerals.

● Alloy steel drill bits are typically used in machine shops for cutting sheet metal of varying thicknesses. These are often the best drill bits for metal if you're working exclusively with thin materials.

Wood Drill Bit: The Ultimate FAQ Guide

Things to know before buying drill bits

1) Drill Bit types

● Brad-point drill bit: This fluted drill bit is designed for use on wood. It features a sharp spur on the tip and spiral grooves (flutes) on the sides. The sharp tip helps position the bit in the right spot, and the flutes are designed to grab wood chips and expel them from the hole as you drill, resulting in a clean hole. Brad-point bits make speedy work of jobs that require a high degree of detail.

● Twist drill bit: This standard bit has a pointed cutting tip and, like the brad-point bit, features fluted sides to remove waste as the hole is being drilled. The twist bit is a general-purpose bit for home use and can be used on wood, thin metal, and plastic.

● Countersink drill bit: Considered a specialty bit, the countersink bit is designed to create a pilot hole with a wider opening at the top for countersinking screw heads. Used mostly on wood, the countersink drill bit allows you to insert the fastener deep enough so the head doesn’t protrude above the surface of the material.

● Forstner drill bit: For use on wood, the Forstner bit, named after its 19th-century inventor, Benjamin Forstner, features the same tip spur as a brad-point bit for precise drilling, but the body of the bit is designed to drill a flat-bottomed hole. Forstner bits are used to create holes to hold dowels (not screws) and are often found in high-end furniture and cabinetry construction.

● Spade drill bit: Also called a paddle bit, a spade bit comes with a tip spur for precision and a flat blade that’s designed to cut large holes—up to 1.5 inches across. Spade bits are commonly used to drill holes through wood studs to run wires and water-supply lines.

● Hole saw drill bit: Used for making large holes in wood, thin plastic, ceramic tile, and other sheet goods, hole saw bits usually come in two pieces: the bit itself—a cylinder with sharp, saw-like teeth—and a mandrel (shaft) that attaches to the bit and fits into the drill.

● Step drill bit: This pyramid-shaped bit is primarily used to enlarge existing holes and is used with thin material—usually sheet metal—but can be used on sheet plastic as well. The manufacturer often labels each “step” on the bit with the corresponding size hole it drills. A step drill bit can also take the place of a countersink bit by widening the top of a hole just enough to recess the fastener head.

2) Size Specs for drill bits

standard drill bits are most often sized in fractional, 1/64th inch increments, commonly ranging from 1/16th inch up to one inch. If you need a larger hole, you can opt for a spade bit or hole saw bit. Bit size may also be labeled in millimeters and decimals, but don’t worry about trying to figure out which sizes are equivalent—conversion charts are posted everywhere bits are sold, and they can be found online as well.

3) Material Matters

● Carbon steel bits are designed for drilling in wood; they shouldn’t be used to drill through metal because they tend to heat up too quickly and may break.

● High-Speed Steel (HSS) drill bits are made by combining alloy metals with tungsten or molybdenum to create a bit that withstands high temperatures better than carbon steel bits. HSS bits are suitable for use on wood, soft metals, and fiberglass.

● Titanium HHS bits feature a thin titanium coating that reduces friction and helps the tips stay sharper, longer. Titanium-coated HHS can be used on wood, fiberglass, hard plastics, and soft metals, such as lead and aluminum.

● Black oxide HHS bits feature a thin coating of oxide that helps reduce rusting and corrosion, making them a good choice for use in humid or wet conditions. They are suitable for use with most surfaces, including wood, thin metal (such as copper sheeting), and fiberglass.

● Cobalt drill bits are manufactured by combining steel alloy with cobalt to form a super-strong drill bit. Cobalt bits are designed for drilling through metals, including aluminum and stainless steel.

● Tungsten carbide drill bits are harder than HHS bits and are used almost exclusively for drilling through ceramic tile and masonry, although the bits’ brittleness makes them more prone to breaking.

Best drill bits for wood?

High-Speed Steel (HSS) drill bits are used for drilling wood, light metals, fiberglass and PVC. Black oxide-coated drill bits are more durable than standard HSS bits and the coating helps the drill bit resist rust. These are best for hardwood, softwood, PVC, fiberglass and steel.

What different between wood drill bit and metal drill bit?

1. Different materials:

Generally, black drill bits are used to drill metal, material high-speed steel is generally used for drill bits. Drill holes on metal materials (alloy steel, non-alloy steel, cast iron, cast steel, non-ferrous metals), and use metalworking drill bits together.

Drilling holes on wood materials, the woodworking drills have a large sales volume, and the hardness of the tool is not high. The tool material is generally high-speed steel.

There is a small sharp point in the center of the drill tip, and the equal angles on both sides are relatively large, or even no angle.

2. The design structure of the drill bit (point, edge, groove type, shank, etc.) is different:

Drill irons are generally pointed in the middle. This structure is more labor-saving, the force is large when drilling, and the wear resistance is conducive to feeding.

While The drill wood is generally a three-pointed blade, the middle is high and the two sides are low. Because the wood is soft, it is faster to drill, and the cutting edges on both sides can make the drill mouth flush and beautiful, also known as thin plate drill.

What is twist drill bit?

● Twist drill bits can be used on light metal, wood, plastic, metal, ceramic and masonry.

Why are drill bits different colors?

Because drill bits are made of different materials and have different surface finishes.

Masonry drill bits normally silver have a wide head on. Gold bits are normally pointed and are for drilling wood etc. Black bits are also pointed headed but for drilling metals.

What is a HSS drill bit?

HSS drill bit is High speed steel drill bit,HSS bits are hard wearing and heat resistant. The large concentrations of chrome and nickel in stainless steel ensure that HSS bits are super strong and durable. HSS drill bits are capable of safely drilling through hardwood, some metals and plastic. They’re safe to operate at high speeds (RPM) and provide long-lasting performance as long as they are maintained

Can I use HSS drill Bits for wood?

Yes, HSS bits are super strong and durable. HSS drill bits are capable of safely drilling through hardwood. They’re safe to operate at high speeds (RPM) and provide long-lasting performance.

Tips for Proper Drill and Drill Bit Maintenance:

● Let the drill bit cool off after you have finished your project.

● Wipe the drill and drill bit with a clean, dry towel or cleaning cloth.

● Use a clean, dry toothbrush to brush off any shavings or other debris that may cling to the tool.

● Apply machine oil lightly with a paper towel or microfiber cloth. Let it sit for a few minutes, then wipe up any excess oil with a new paper towel.

● Inspect drill bits for any extensive damage and remove damaged drill bits from the set so they can be replaced.

● Place drill bits back into their case and store in a cool, dry place.
