Measurement System

Fractional Inch & Metric

Fractional inch and metric are measurement systems used to indicate the size of drill bits that have standard trade sizes.

Letter

Letter-size drill bits are each assigned a trade letter size that indicates their compatibility with other bits that have the same trade letter size. The larger the letter size, the larger the drill bit.

Wire

Wire-size drill bits are each assigned a wire size that matches an American Wire Gauge (AWG) size, which helps ensure compatibility when inserting wires into holes made by the bits. The larger the wire size, the smaller the drill bit.

Drill Bit Size

Drill bit size is the diameter of a drill bit, which determines the diameter of a hole that can be created by the bit during drilling tasks.

Drill Bit Point Angle

Drill bit point angle is the included angle at a drill bit's tip where its cutting edges meet. Drill bits with a small (or steep) drill bit angle, such as a 90° drill bit angle, are used for drilling softer materials such as plastic.

A 118° drill bit angle is common on general purpose drill bits used for drilling a range of materials, such as wood, aluminum, and plastic.

Drill bits with a large (or flat) drill bit angle, such as a 135° split-point angle, are used for drilling harder materials such as stainless steel or titanium.

Taper-Length Drill Bits

Available108 products

Taper length drill bits have a longer flute length and can drill deeper holes than jobber-length drill bits of the same size. Sometimes called long-series drill bits or long jobber drills, they are shorter than extended-length bits. The bits' shank diameter and flute diameter are the same.

Finish - Machining

Straw/Bronze Finish Spiral-Flute Cobalt Taper Length Drill Bits

These bits have a straw/bronze finish that improves their wear resistance. Cobalt drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel drill bits. They provide some shock absorption and can be used in handheld power tools. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
