12 mm Jobber Drill Bit

The Chicago-Latrobe 47347 is a general-purpose jobber length drill bit made from high speed steel with a black oxide finish. It suits mechanics and fabricators who need a reliable metric bit for everyday drilling tasks in metal and other materials.

Upgrade from worn or undersized bits

Replacing dull or smaller diameter bits with this 12 mm size restores clean hole cutting and reduces wandering. The jump is worth it when existing bits no longer hold a sharp edge or when a precise 0.4724 inch hole is required for fastener clearance.

118 degree conventional point for standard drilling

The 118 degree point angle and conventional point type handle common ferrous and non-ferrous metals comfortably. It runs out in deep holes where coolant-through capability would be needed or when drilling highly abrasive alloys that demand specialised coatings.

Questions about this item

What chuck size does the 12 mm jobber drill bit require?

Use a chuck that opens to at least 12 mm or .4724 in to hold the straight shank securely.

How do I start the 118° conventional point without it walking?

Centre-punch the workpiece, apply steady pressure, and keep the drill perpendicular so the conventional point bites cleanly.

When should I replace this high-speed steel bit?

Replace it when the cutting lips are chipped, the black-oxide coating is worn away, or the bit no longer cuts cleanly at proper speed.
