Cobalt Threaded Shank Drill 5/16 in

This cobalt threaded shank drill bit is built for precision drilling in hard metals such as stainless steel and titanium. The 135-degree split point reduces walking and starts on contact for accurate hole placement. A black oxide finish adds lubricity and resists corrosion during heavy use. It fits tools accepting a 1/4-28 threaded shank.

Suited for metalworkers using 1/4-28 drive systems

Machinists and maintenance technicians who need a short-length cobalt bit for tough alloys will benefit from the heat resistance and rigidity. Users requiring a straight shank for standard drill chucks or a longer flute length for deep holes should look at other configurations. The fixed thread size limits compatibility to matching holders only.

1/4-28 threaded shank determines fit

The 1/4-28 thread is the single specification that decides whether this bit mounts in your tooling. Verify the spindle or adapter accepts this exact thread pitch before purchase. No other shank dimensions are offered for this model.

Questions about this item

What comes in the package and is anything else needed to start drilling?

The box contains the cobalt threaded-shank drill bit with a 135-degree point and 1/4-28 threads; no extra parts are required to use it in a compatible chuck.

How do I decide which version of this drill bit to buy?

This listing is for a single 5/16-inch size with 1/4-28 threading, so there are no alternative capacities or versions to choose from.

The 135-degree split point centres the bit quickly and reduces walking on hard materials such as stainless steel or titanium.
