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 can you drill with HSS drill bit?
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.6 days ago.
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.
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.
What are HSS step bits used for?
Step drills are used for cutting varying hole sizes in material up to 4mm thick without changing the drill bit. Each drill cuts parallel holes within a specific size range, rising in 2mm increments. Made from HSS (High Speed Steel).
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.
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 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 kind of drill do you use for concrete?
The preferred tool for drilling into concrete is a hammer drill.
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 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 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.
Can you use brass drill bits on metal?
1) Metal drill bits Metal drill bits with a partially ground tip are suitable for non-ferrous metals. These include aluminum, copper, brass, zinc, iron and non-alloy steel.
What drill bit is used for stainless steel?
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.
Can you use a drill to cut metal?
Conventional drill bits cannot cut through metal so you need a heavy-duty, hard drill bit. Two types of drill bits are suitable for metalworking jobs: titanium and cobalt.
What is a Unibit used for?
A unibit (often called a step drill bit) is a roughly conical bit with a stairstep profile. Due to its design, a single bit can be used for drilling a wide range of hole sizes. Some bits come to a point and are thus self-starting. The larger-size bits have blunt tips and are used for hole enlarging.
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.
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.
Will stainless steel rust if you drill it?
Stainless steel is best known for its strength and ability to withstand corrosion. These properties quickly become the greatest foes when drilling stainless steel.
