What Are Hss Drill Bits

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. HSS bits can be also be used for drilling wood and plastic materials.

What do you use HSS drill bits for?

High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum. Cobalt drill bits are extremely hard and dissipate heat quickly. They’re mostly used for boring in aluminum and tough metals such as stainless steel.

Are HSS drill bits any 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.

What is the difference between HSS and SDS drill bits?

The drill has an “SDS” drive configuration, and has to have “SDS” bits to fit into it. HSS stands for “High Speed Steel” which is just the material of construction of the bit. It refers to an alloy that is good for drilling through steel at high cutting speeds without losing hardness or its edge.

Are HSS drill bits for metal?

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.6 days ago.

Can HSS drill stainless steel?

HSS or High-Speed-Steel bits are designed for use on stainless steel and can be used for hand and machine drilling.

What are HSS?

Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. The use of HSS is growing with popularity all around the world in the building industry and in the United States accounts for approximately 18% of the structural steel market.

Which is better HSS or carbide?

Carbide is much harder, so it has a longer tool life and faster cutting data than conventional high speed steel. HSS doesn’t have the wear resistance and lifespan of carbide, so it tends to be more resilient and less brittle and is the best choice for deep cuts with small tip sizes in harder materials.

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.

What is the difference between HSS and HSSE?

Both the spellings HSSE and HSS-E are commonly used. If you want to buy a twist drill or tap with cobalt alloy, you will often find the designation HSS-E Co 5% or HSSE Cobalt 8%. Other descriptions are also possible. It is commonly believed that HSS-E steels are superior to normal HSS steels in all respects.

What does SDS stand for on a drill?

But what is an SDS drill? SDS stands for Slotted Drive Shaft or Slotted Drive System. SDS bits are inserted into the chuck to make a rotary hammer or a hammer drill.

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.

Can I use an SDS drill bit in a hammer drill?

You should not use SDS drill bits in a standard drill. The chuck on a standard rotary or hammer drill is not designed for SDS drill bits. Standard bits can come loose, damage the drill and affect the quality of your work.

What type of drill bits are best for metal?

Regular drill bits can’t cut through steel, so you need a heavy-duty, hard drill bit to do the job. There are two types of drill bits that you can count on for metalworking projects: titanium and cobalt. Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating.

What Colour are HSS drill bits?

Conventional HSS step bits are black, but the ones best for drilling metal are gold, because they are coated with titanium nitride for reduced friction and longer wear.

Can HSS drill bits be used 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.

What RPM should you drill stainless steel?

Feed and speed rates should be reduced up to 45-50‰ when drilling holes deeper than 4 drill diameters.Recommended Speeds for Carbide Tipped Holecutters. Size Steel Stainless Steel 1-1/4 to 1-9/16 in. 300 – 600 RPM 175 – 315 RPM 1-5/8 to 2 in. 200 – 500 RPM 120 – 225 RPM.

Which drill bit is best for stainless steel?

carbide-infused drill bits are one strong option when drilling into stainless steel. Infusing drill bits with cobalt is another way that manufacturers achieve ultrahard drill bits. High-speed steel, also known as HSS, is the most common drill bit for metal applications. Cobalt bits are an extension of HSS bits.

What black oxide drill bits are used for?

Black Oxide Drill Bits – Basic and Inexpensive 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. Black oxide bits last up to 50% longer than standard HSS bits.
