15/64" x 8" Extra-Long Drill Bit

This high-speed steel drill bit measures 15/64 inch in diameter and 8 inches overall, giving extra reach for deep-hole drilling. It suits production, maintenance and portable drilling tasks across a wide range of materials including aluminium, brass, copper, metal, plastic and wood. The 118° conventional point and round shank fit standard tool-holding systems.

Installation and Common Issues

Chuck the round shank securely in any compatible drill before starting. Apply steady pressure and use cutting fluid when drilling iron or steel to prevent overheating and premature dulling. The extra length can amplify run-out, so check alignment frequently to avoid wandering holes or bit breakage.

Pre-Purchase Checks

Verify that your drill chuck accepts a 15/64" shank and that the machine provides enough spindle travel for the 8-inch bit. Confirm the workpiece material is listed among the recommended metals, plastics or woods. Note the Proposition 65 warning: this product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

Questions about this item

How can I confirm the 118° point is cutting cleanly after I start drilling?

The 118° conventional point should produce a steady stream of chips and a round hole without walking; if the bit chatters or the hole is oval, resharpen or replace it.

What comes in the package and is a drill chuck included?

The package contains the single 15/64" x 8" high-speed steel bit with a round shank; a compatible drill chuck or collet must be supplied separately.

When should I choose this 15/64" diameter over another size?

Select this 15/64" bit when the hole diameter must match that exact fractional size; other diameters are offered for different hole requirements.
