Screw Machine Drill Bit 7/16 in Cobalt
This Chicago-Latrobe screw machine drill bit measures 7/16 inch with a decimal equivalent of 0.4375. It features a 135-degree split point made from cobalt steel with a straw finish. The right-hand cutting direction suits standard drilling operations.
Best for precision metal drilling.
The split point design starts accurately without a centre punch, reducing walk on hard materials. Cobalt construction resists heat during extended use in steel or alloys. Buyers needing internal coolant delivery should look elsewhere, as this bit is non-coolant through.
135-degree split point geometry
The 135-degree point angle centres the bit quickly and reduces thrust required. Split point geometry prevents wandering on contact with the workpiece. This single specification determines suitability for hard-metal drilling without pilot holes.

What shank size must my drill chuck accept to use this 7/16-inch bit?
This screw machine drill bit has a 7/16-inch diameter shank, so your chuck must accommodate at least that size.
Will the right-hand cutting direction work with my older reversible drill?
