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.

Can you use drill chart to convert sizes?

You can use the drill chart that follows this section to help convert sizes, or you can do the math yourself.

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.

Which drill bit has the wider flute?

Parabolic spiral flute drill bits have wider flutes for more efficient chip evacuation than spiral-flute bits. Black-oxide drill bits produce less friction than uncoated drill bits. Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and black-oxide drill bits.

Which drill bit is the most wear resistant?

Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits. Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.

What is an uncoated flute bit?

Uncoated. 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 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 is a short flute drill bit?

Short-Flute Cobalt Steel Drill Bits. The short flutes on these jobbers’ -length bits provide increased rigidity for drilling straighter holes. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.

What is a TiN drill bit?

Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.

What is a split point in a bit?

A split point keeps the bit centered without a pilot hole.
