Drill America 35/64" HSS Stub Drill Bit

The Drill America DWDST35/64 is a high-speed steel stub drill bit with a 35/64 inch diameter. It conforms to National Aerospace Standard 907 for screw machine drills. The short, rugged construction suits portable or machine drilling in automotive and construction settings. Buyers needing longer flute length or larger diameters should select a different drill style.

135 Degree Split Point Self-Centering Geometry

A 135 degree split point allows the bit to self-center and reduces thrust during drilling. This geometry improves accuracy when starting holes without a pilot drill. The stub length limits reach, so the bit is not suited for deep-hole applications. Drilling tasks requiring extended depth need a jobber or taper-length drill instead.

California Proposition 65 Chemical Warning Applies

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Users should review safety data and follow handling precautions before use. The warning applies to the drill bit itself and does not depend on the workpiece material. Compliance with local regulations remains the responsibility of the purchaser.

Questions about this item

How do I pick the right DWDST stub drill size for my job?

Choose the 35/64" bit when you need that exact fractional diameter; smaller sizes below 1/16" and #52 switch to a 118° point instead of the 135° split point.

What does the 135° split point actually do on the machine?

The 135° split point is self-centering and reduces thrust, so the bit starts cleanly without wandering and needs less feed pressure in portable or machine drilling.

How does the NAS 907 standard limit what this stub drill can handle?

NAS 907 defines the short, rugged screw-machine dimensions that fit tight spindle clearance, making the bit ideal for automotive and construction work where length is restricted.
