Drill America 13/64" Extra Long Bit

This 13/64" x 8" high-speed steel drill bit is built for general-purpose drilling where extra reach is required. It suits production, maintenance and portable drilling tasks across a broad range of ferrous and non-ferrous materials. The 118° conventional point and round shank suit standard toolholding systems. Buyers needing shorter lengths or specialised coatings should look elsewhere.

Round Shank and 118° Point

The round shank allows the bit to fit a wide range of toolholding systems without proprietary adapters. The 118° conventional point is designed for general-purpose performance in materials such as aluminium, brass, copper, metal, plastic and wood. No additional accessories or software are bundled with this single bit. Users requiring hex shanks or split-point geometry will need a different product.

Check Chuck Capacity and Reach

Verify that your drill chuck accepts a 13/64" round shank before ordering. Ensure the 8" overall length provides the reach your application demands without exceeding the tool's capacity. The item carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Buyers needing different diameters or shorter overall lengths cannot use this model.

Questions about this item

How often will the 13/64" HSS bit need resharpening when drilling steel?

Resharpen the 118° point when cutting edges dull; frequency depends on material hardness and feed pressure, but HSS typically requires periodic grinding to maintain performance.

What limits continuous drilling depth with this 8" extra-long bit?

The 8" flute length sets the maximum hole depth in a single pass; chip evacuation becomes harder deeper in the hole, so withdraw frequently to clear swarf.

How much heat builds up in the shank during all-day production drilling?

High-speed steel generates noticeable heat at the shank during sustained use; use cutting fluid and allow cooling pauses to prevent temper loss and maintain hardness.
