How do I know what size drill bit to use?

The diameter of the hole you drill should be slightly smaller than the diameter of the screw. So, for example, if you’re using a 3.5 mm screw, use a drill bit with a diameter of 3 mm. If you’re using wall anchors as well as screws, the drill bit and anchors should have the same diameter.

How do I know what size my drill bit is?

Typical drill bits have markings somewhere on the shank above the threads. It’s small, but it usually has the drill-bit diameter stamped into the metal; the number is written in fractions. For example, the markings may read: 1/4-inch, 3/6-inch or 25/32.

What is the largest drill bit size?

This chart rounds out the second half of these number gauge sizes down to #1, which is the largest drill bit size.

How Do You Know What Size Drill Bits You Need?

If you’re an average weekend-warrior, you’ve probably stared at a screw or bolt for a few moments and wondered what size drill bit you would need.

What is the typical drill bit angle?

The typical sizes of drill bit point angles are 115° or 118° (degrees).

What size drill is used for letter gauge?

Letter gauge drill sizes are used primarily in North American with A starting with the smallest size working 26 size increments to Z.

How to size screws?

First, you can size screws simply by inserting them into a hole then reading the marking.

Can we narrow down a bit?

Thankfully, we can narrow it down a bit to some standard sized holes and bits.

Is there a larger set of fasteners?

There are indeed larger sets. Specialty fasteners sometimes call for a size that would be considered uncommon.

What are slow spiral drill bits?

Drill Bits for Aluminum, Brass, and Bronze. Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits.

What are the bits called that are used to set a nut?

These bits are also known as nut setters.

What are the flutes on a jobber’s bit?

The short flutes on these jobbers’ -length bits provide increased rigidity for drilling straighter holes.

Why are solid carbide bits used?

Harder, stronger, and more wear resistant than high-speed steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

How fast can cobalt steel run?

With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life.

What is a three edge cutting edge?

Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits.

What are slow spiral drill bits?

Also known as slow-spiral drill bits. They are jobbers’ length and have the rigidity and length required for most applications.

What are carbide drill bits made of?

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers’-length drill bits. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. They have either a four-facet or split point to keep the bit centered without a pilot hole.

What is reverse flute bit?

Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws. These bits are jobbers’ length and have the rigidity and length required for most applications.

What is a solid carbide bit?

Harder, stronger, and more wear resistant than high-speed steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing.

What are carbide tipped bits?

More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material , such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

What are jobber bits made of?

These jobbers’ -length bits have the rigidity and length required for most applications. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

How fast can cobalt steel run?

Access hard-to-reach spots and drill deep holes. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. The split point keeps the bit centered without a pilot hole.

What is the measurement of drill bits?

Drill bits are available in different materials, lengths, and diameters. Most are measured by the metric units and in the USA it’s imperial units. Drill bit diameter is the most important factor in the drilling process and it should know precisely as much as possible to sharpen or tolerate the diameter.

How many mm is 1 inch?

1 inch is equal to 25.4 mm. By dividing the inches other fractions are introduced. Inches are really popular in the USA but beyond that mostly used the SI units. So we have to interchange the metric units and imperial units.
