What are HSS drill bits used for?

by Duane Holloway | views: 250

HSS drill bits, an acronym for high speed steel drill bits are extremely hardwearing and particularly well designed for drilling into metal surfaces, as they are much more resistant to the heat generated from the fast speed operation. The front edges cut the material, whilst the spirals remove debris from the hole.

In respect to this, what can you drill with hss drill bit?

HSS drill bits are suitable for drilling iron, steel, and other metals such as brass, copper, and aluminum alloy. When drilling metals, HSS drill bits are more resistant to the heat created by the high-speed operation.

You might also wonder, can you use hss drill bits for masonry? Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits. They're effective for drilling tile and masonry.

Also, you may want to know, what are hss steel drill bits used for? HSS or high-speed steel bits are made from carbon steel with the addition of other elements such as chrome and vanadium. This allows them to be used at high drilling speeds. HSS bits can be used to drill iron, steel and other metals such as brass, copper and aluminum alloy. They can also be used to drill plastic.

Can you use HSS drill bits for concrete?

Carbide tipped: Carbide is an extremely strong metal that withstands enormous force. Carbide is also expensive, so tool manufacturers often use HSS for the shank, flutes and leads but add a piece of carbide to the point. Carbide tip bits are popular for masonry, concrete and tile drilling.

23 Related Questions & Answers

Are HSS drill bits good?

HSS bits are hardwearing 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.

Can HSS cut stainless steel?

High-speed steel tools can be used on stainless steel, but shorter drills are the most effective as they are less susceptible to deflection. The best HSS drills for stainless steel are alloyed with tungsten or molybdenum.

Can you use HSS drill bits for tiles?

It's highly unlikely that tiles will have been installed atop of metal or alloys but there could be some metal struts or supports behind the substrate – if you need to drill into them then a standard high-speed steel (HSS) drill bit should do the trick.

Can HSS drill bits be used for wood?

Materials and Finishes

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.

What is the difference between HSS and SDS drill bits?

HSS drill bits fit into any standard chuck, either with a key or the keyless type. SDS+ fit into a special chuck with a groove on one side for the bit to fit into ( there's no physical tightening of the chuck as it's a positive lock on these) SDS Max is a variation of the last one but it's a lot bigger than SDS+.

Which is better HSS or carbide?

Carbide steel has more high cutting speed and is 4- 7 times higher than high – speed steel. Carbide is much harder, so it has a longer tool life and faster cutting data than conventional high speed steel. HSS tools also cost less than Carbide tools and are often a good solution in high-mix, low-volume applications.

How hard is HSS?

At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above Rockwell hardness 60) and abrasion resistance (generally linked to tungsten and vanadium content often used in HSS) compared with common carbon and tool steels.

Will HSS cut hardened steel?

You want a cobalt bit, as it's a type of high-speed steel (HSS) that has more cobalt in it and is strong enough to cut through hardened steel.

What drill bit is best 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.

What type of drill do I need for concrete?

The best drill for concrete today is one of two tools: A hammer drill or a rotary hammer. They both do essentially the same thing but are vastly different tools.

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 are the toughest drill bits?

The basis for many of the hardest drill bits is tungsten carbide. A metal that is five times stronger than steel, tungsten carbide by itself makes for a very hard drill that's quite resistant to heat.

What is the best drill bit to go through 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 is the best type of drill bit for hardened steel?

Clearly, the best drill bits for hardened metal or steel come with a cobalt blend. These cobalt drill bits use an alloy including 5%–8% cobalt. This cobalt makes up part of the steel blend, so the hardness of the bit doesn't wear off with a coating (like titanium bits). It runs throughout the entire bit.

What type of steel is HSS?

High speed steel (HSS) is one such alloy steel that contains tungsten, and in addition, the alloying element vanadium (for increased strength).

What is HSS tap?

Faithfull HSS Straight Flute Taps are used to cut threads in blind or through holes in most materials. They are manufactured to ISO529 standard and are suitable for hand or machine cutting.
