High-Speed Steel Jobbers' Length

Our basic drill bit material is also the most versatile. These jobbers' bits have the balance of rigidity and length needed for most applications.
Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.
Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

Carbide Jobbers' Length
|
Round Shank |
The hardest and most wear-resistant drill bits you can buy in a length that's rigid enough for most applications. These bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
Uncoated—Excellent for a range of metals, they perform best when used on steel, aluminum, brass, and bronze.
Round Shank—The most common shank type fits in a drill press chuck.
Four-Facet Point—The most accurate point style, it centers the bit without a pilot hole and keeps the bit stable while drilling hard metals.
