What are black drill bits for?

Black Oxide Drill Bits – Basic and Inexpensive

This reduces friction between bit and workpiece, thereby speeding up the drilling process. Bits made with a black oxide coating are suitable for work on steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, and composite materials.

What do the Colours of drill bits mean?

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.

Are black drill bits for metal or wood?

Black oxide-coated HSS drill bits have a finish designed to help resist corrosion and increase durability. They last longer than basic HSS bits and work well on a variety of materials including metal, hardwood, softwood, PVC and fiberglass.

Why are some drill bits black and some silver?

If you're drilling through hardened metal, even an HSS bit can wear out quickly, and you may need one made from tungsten carbide or titanium. The black or blue-gray color on metal boring bits comes from a coating or black oxide or titanium carbo-nitride, designed to reduce friction and extend bit life.

What's the difference between black and gold drill bits?

Black oxide bits have 50% longer life than standard high speed steel bits. Click here to see available sizes. Gold Oxide – Offers added speed and durability for general purpose drilling applications in wood, metal and plastic and drills 3x faster with speed helix. Click here to see available sizes.

Are Black Oxide Drill Bits Good?

What drill bit is best for metal?

Cobalt drill bits are the best drill bits for hard metals including stainless steel. If you are using a hand drill then a 5% (M35) drill bit will be most suitable and it will be less brittle than other drill bits. TTP HARD drill bits are 5% cobalt and are a high quality drill bit.

What colour drill bit is for metal?

Usually, drill bits that are for metal can be distinguished by their black color. They are also usually made from tungsten carbide, cobalt or titanium, which should be noted on the packaging if you're buying new.

How can you tell if a drill bit is for masonry?

Masonry Drill Bits – Best for Stone and Brickwork

Masonry bits look like larger twist drills with a slightly tighter corkscrew shape. You can identify them thanks to their wide arrow-shaped heads. They're commonly used in hammer drills to grind masonry down as they cut through it.

What color drill bits are for wood?

Wood bits usually aren't coated in everything, and generally, just have a silver color. On the other hand, metal drill bits, due to being coated in cobalt, black oxide, or titanium, are often copper or golden colored, as well as dark gray or black.

How can you tell if a drill bit is for wood?

Wood Drill Bits: These can be identified by a small, pointed tip at the very end. If you look closely, you can see spurs on each side. These grab wood and carve it away. Steel bits are great for softwood varieties; hardwoods will eventually dull them.

What drill bit do you use for screws?

The drill bit should be the same size as the shaft of the screw without accounting for the threads. To do this, simply line up a screw side by side with the drill bit. If they're the same size, then you're good to go.

What drill bit is for brick?

Masonry or mortar drill bits are the only type that can penetrate brick or mortar with ease. These bits are designed to deal with particular materials, so the central part of the bit is made of steel, while the tip has tungsten carbide to help it cut through tough walls.

What drill bit do I need for concrete?

Drill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest; when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.

Can you use a regular drill to drill into concrete?

It is possible to drill into concrete with an ordinary rotary drill. Rotary drills take longer to drill into concrete than hammer drills and more physical effort is required. Excessive heat build-up can break the drill bit. One way to speed up the process and avoid breaking the drill bit is to keep the bit cool.

Can I use a masonry bit with a regular drill?

You can use a masonry drill bit with a regular drill to drill holes through brick and other masonry without having to use a hammer drill. The main advantage of a hammer drill is that it not only rotates the bit but strikes or hammers the masonry to help break through the surface.

Which drill bit is for walls?

Masonry drill bits

These bits range in size from 4mm to 16mm and can come in huge lengths of up to 400mm to enable you to drill through walls.

How good are black oxide drill bits?

Black oxide bits last up to 50% longer than standard HSS bits. They offer superior durability and speed. Many pros find they get years of use from them and consider black oxide bits the best general-purpose drill bits you can buy.

What is the difference between drill bits for wood and metal?

The main difference between a metal and wood drill bit is in geometry. The wood bit has a spur in the center that will penetrate the wood and keep the bit stable during drilling. The metal bit is a twist bit with conical cutting tips followed by spiral flutes.

What kind of drill bit do I need for aluminum?

Aluminum is a soft metal and therefore a standard HSS drill bit will be able to drill into it. However because of the low melting point of aluminium a better choice would be to use a cobalt drill bit.

Why can't I drill through metal?

Drilling through metals create a lot of friction. This friction generates heat. The heat generated in the process not only damages your drill bits, but can also damage the metal you are drilling into.

What is the strongest drill bit?

Polycrystalline diamond (PCD) is one of the hardest drill bit material, which can be used on the toughest materials, such as glass and ceramic.

What are Black and Gold drill bits used for?

Black & Gold metal drill bitst are made of heavy-duty High Speed Steel for drilling into a variety of materials including plastic, wood, and metal. Each bit features a 135° split point tip design to help reduce walking.
