9/64" HSS Jobber Drill Bit

The Westward 5XL71 is a fractional-inch jobber-length drill bit made from high-speed steel with a black-oxide finish. It is suited for general-purpose drilling in metal, wood and plastic for trade professionals and DIY users.

Check shank fit and material

Verify that your drill chuck accepts a straight shank of this fractional diameter and that the 135-degree split-point geometry matches the material you intend to drill. Confirm the decimal equivalent .1406 aligns with your project specifications before ordering.

Black oxide finish benefits

The black-oxide surface treatment reduces chip welding and improves lubricity during cutting, extending bit life in repetitive operations. No coolant-through capability is provided, so external lubrication may be required for deeper holes.

Questions about this item

What is included with the Westward 5XL71 9/64" HSS Black Oxide 135° Jobber Drill Bit and what else might I need?

The box contains the single 9/64 inch drill bit with a 135 degree split point made from high speed steel with a black oxide finish. You will need a drill chuck that accepts a straight shank of this diameter and appropriate cutting fluid or lubricant for the material you are drilling.

How do I decide between the fractional 9/64 inch size and its decimal equivalent when ordering?

The bit is identified as 9/64 inch, which is exactly 0.1406 inch in decimal form. Both figures refer to the same drill bit; choose the notation that matches your drawing or tooling list.

What does the 135 degree split point mean for everyday drilling in metal?

The 135 degree split point is designed to self-centre on contact and reduce walking, so the bit starts cutting immediately in steel and other hard materials without a centre punch.
