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.
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.
Can HSS drill bits be used 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 does HHS mean in drill bits?
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is often used in power-saw blades and drill bits.
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 steel?
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.
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 I use a masonry drill bit on metal?
The masonry of the brick will dull a metal drill bit in a matter of seconds. A masonry drill bit is carbide tipped and can take the abuse of drilling into masonry. You can for a few minutes until it’s so dull you just watch it turn and heat up. In hammer function mode it will go in but will also fill up pretty quickly.
What kind of drill do you use for concrete?
The preferred tool for drilling into concrete is a hammer drill.
How can you tell if a drill bit is for masonry?
Masonry Drill Bits – Best for Stone and Brickwork 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. You can use them on brickwork, stone, breeze blocks, and other hard stone surfaces.
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.
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 M2 HSS?
M-2 High Speed Steel M-2 is a tungsten-molybdenum high-speed steel. It is a popular grade for cutting and non-cutting applications. In addition, M2 steel has a resistance to decarburization that is characteristic of tungsten types and M2 offers an excellent combination of red hardness, toughness, and wear resistance.
What drill bit is best for hardened 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.
Which drill bit is for metal?
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.
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.
What is the difference between a hammer drill and an SDS drill?
SDS Rotary Hammers are similar to Hammer Drills in that they also pound the drill bit in and out while it’s spinning. They use a piston mechanism instead of a special clutch enabling them to deliver a much more powerful hammer blow than traditional Hammer Drills – they are able to drill larger holes much faster.
Can you convert a normal drill to SDS?
You can remove the chuck from a standard corded electric drill and replace it with an SDS chuck.
