Drill bits are generally classified as Twist Drill, Counterbore, Countersink, Flat Bottom Boring, and Specialty. On our web site we have divided these into two categories: Drill Bits – Normally used with hand held drills or drill presses fitted with standard chucks.
What is drilling types of drill bits?
– Twist Drill Bits. Also known as high-speed bits, they resemble corkscrews and are some of the most popular bits.
– Brad Point Drill Bits.
– Masonry Drill Bits.
– Rivet Drill Bits.
– Spade Drill Bits.
– Installer Bits.
– Step Bits.
– Auger Bits.
How do you identify a drill bit?
– 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.
– Masonry Drill Bits: These bits have a gently sloping tip.
– Metal Drill Bits: These have a wide-angled point at the end, and they may also be painted black.
What do different color drill bits mean?
The Color of High Speed Steel All drill bits are made from steel, but high speed steel bits are an improvement over conventional steel ones. 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.
How do I know what drill bit to use?
– Use a bit 1/64” smaller than the target hole size for softwoods.
– Use a bit exactly the same size as the hole when working on other materials.
– If you’re not sure which to select, choose a drill bit 1/64” larger than the hole you wish to create.
Why are some drill bits gold?
Twist bits are also available coated with Titanium nitride (TiN), these are easily identified by the gold like colour. This coating increases the hardness of the bit and adds a self-lubricating property.
What’s the difference between black and gold drill bits?
Black oxide bits have 50% longer life than standard high speed steel bits. 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.
How can you tell if a drill bit is for wood or metal?
What is the difference between drill bits?
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. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits. They’re effective for drilling tile and masonry.
